Geography of Bangladesh

Bangladesh  is a low-lying, riverine country located in South Asia with a largely marshy jungle coastline of 710 km (441 mi) on the northern littoral of the Bay of Bengal. Formed by a delta plain at the confluence of the Ganges (Padma), Brahmaputra (Jamuna), and Meghna Rivers and their tributaries, Bangladesh's alluvial soil is highly fertile, but vulnerable to flood and drought. Hills rise above the plain only in the Chittagong Hill Tracts in the far southeast and the Sylhet division in the northeast. Straddling the Tropic of Cancer, Bangladesh has a tropical monsoon climate characterized by heavy seasonal rainfall, high temperatures, and high humidity. Natural disasters, such as floods, tornadoes, and tidal bores affect the country yearly. Bangladesh also is affected by major cyclones, on average 16 times a decade. A cyclone struck the southeastern coast in May 1991, killing 136,000 people. Cyclone Sidr struck the southwestern coast on November 15, 2007, affecting not only the coastal districts of the administrative division Khulna but also about half of the tropical forest Sundarbans.

Physical geography

Physical Overview

Most of the areas of Bangladesh lies within the broad delta formed by the Ganges and Brahmaputra rivers. Lands are exceedingly flat, low-lying, and subject to annual flooding. Much fertile, alluvial soil is deposited by the floodwaters. The only significant area of hilly terrain, constituting less than one-tenth of the nation's territory, is the Chittagong Hill Tracts in the narrow southeastern panhandle of the country. There, on the border with Burma, is Mowdok Mual (1003 m/3292 ft), the country's highest peak. Small, scattered hills lie along or near the eastern and northern borders with India. The eroded remnants of two old alluvial terraces-the Madhupur Tract, in the north central part of the country, and The Barind, straddling the northwestern boundary with India- attain elevations of about 30 m (about 100 ft). The soil here is much less fertile than the annually replenished alluvium of the surrounding floodplain.

The physical geography of Bangladesh is varied and has an area characterized by two distinctive features: a broad deltaic plain subject to frequent flooding, and a small hilly region crossed by swiftly flowing rivers.The country has an area of 147,570 square kilometers and extends 820 kilometers north to south and 600 kilometers east to west. Bangladesh is bordered on the west, north, and east by a 4,095-kilometer land frontier with India and, in the southeast, by a short land and water frontier (193 km) with Burma (Myanmar). On the south is a highly irregular deltaic coastline of about 580 kilometers, fissured by many rivers and streams flowing into the Bay of Bengal. The territorial waters of Bangladesh extend 12 nautical miles (22 km), and the exclusive economic zone of the country is 200 nautical miles (370 km). Roughly 80% of the landmass is made up of fertile alluvial lowland called the Bangladesh Plain. The plain is part of the larger Plain of Bengal, which is sometimes called the Lower Gangetic Plain. Although altitudes up to 105 meters above sea level occur in the northern part of the plain, most elevations are less than 10 meters above sea level; elevations decrease in the coastal south, where the terrain is generally at sea level. With such low elevations and numerous rivers, water—and concomitant flooding—is a predominant physical feature. About 10,000 square kilometers of the total area of Bangladesh is covered with water, and larger areas are routinely flooded during the monsoon season. The only exceptions to Bangladesh's low elevations are the Chittagong Hills in the southeast, the Low Hills of Sylhet in the northeast, and highlands in the north and northwest. The Chittagong Hills constitute the only significant hill system in the country and, in effect, are the western fringe of the north-south mountain ranges of Burma and eastern India. The Chittagong Hills rise steeply to narrow ridge lines, generally no wider than 36 meters, with altitudes from 600 to 900 meters above sea level. At 1,052 meters altitude, the highest elevation in Bangladesh is found at Mowdok Mual, in the southeastern part of the hills. Fertile valleys lie between the hill lines, which generally run north-south. West of the Chittagong Hills is a broad plain, cut by rivers draining into the Bay of Bengal, that rises to a final chain of low coastal hills, mostly below 200 meters, that attain a maximum elevation of 350 meters. West of these hills is a narrow, wet coastal plain located between the cities of Chittagong in the north and Cox's Bazar in the south. About 67% of Bangladesh's nonurban land is arable. Permanent crops cover only 2%, meadows and pastures cover 4%, and forests and woodland cover about 16%. The country produces large quantities of quality timber, bamboo, and sugarcane. Bamboo grows in almost all areas, but high-quality timber grows mostly in the highland valleys. Rubber planting in the hilly regions of the country was undertaken in the 1980s, and rubber extraction had started by the end of the decade. A variety of wild animals are found in the forest areas, such as in the Sundarbans on the southwest coast, which is the home of the Royal Bengal Tiger. The alluvial soils in the Bangladesh Plain are generally fertile and are enriched with heavy silt deposits carried downstream during the rainy season.

Human geography

Urbanization is proceeding rapidly, and it is estimated that only 30% of the population entering the labor force in the future will be absorbed into agriculture, although many will likely find other kinds of work in rural areas. The areas around Dhaka and Comilla are the most densely settled. The Sundarbans, an area of coastal tropical jungle in the southwest and last wild home of the Bengal Tiger, and the Chittagong Hill Tracts on the southeastern border with Burma and India, are the least densely populated.

Climate

Bangladesh has a tropical monsoon climate characterized by wide seasonal variations in rainfall, high temperatures, and high humidity. Regional climatic differences in this flat country are minor. Three seasons are generally recognized: a hot, muggy summer from March to June; a hot, humid and rainy monsoon season from June to November; and a warm-hot, dry winter from December to February. In general, maximum summer temperatures range between 38 and 41 °C (100.4 and 105.8 °F). April is the hottest month in most parts of the country. January is the coolest month, when the average temperature for most of the country is 16–20 °C (61–68 °F) during the day and around 10 °C (50 °F) at night. . Winds are mostly from the north and northwest in the winter, blowing gently at 1 to 3 kilometers per hour (0.6 to 1.9 mph) in northern and central areas and 3 to 6 kilometers per hour (1.9 to 3.7 mph) near the coast. From March to May, violent thunderstorms, called northwesters by local English speakers, produce winds of up to 60 kilometers per hour (37.3 mph). During the intense storms of the early summer and late monsoon season, southerly winds of more than 160 kilometers per hour (99.4 mph) cause waves to crest as high as 6 meters (19.7 ft) in the Bay of Bengal, which brings disastrous flooding to coastal areas.

Heavy rainfall is characteristic of Bangladesh causing it to flood every year. With the exception of the relatively dry western region of Rajshahi, where the annual rainfall is about 1,600 mm (63.0 in), most parts of the country receive at least 2,300 mm (90.6 in) of rainfall per year. Because of its location just south of the foothills of the Himalayas, where monsoon winds turn west and northwest, the region of Sylhet in northeastern Bangladesh receives the greatest average precipitation. From 1977 to 1986, annual rainfall in that region ranged between 3,280 and 4,780 mm (129.1 and 188.2 in) per year. Average daily humidity ranged from March lows of between 55 and 81% to July highs of between 94 and 100%, based on readings taken at selected stations nationwide in 1986. About 80% of Bangladesh's rain falls during the monsoon season. The monsoons result from the contrasts between low and high air pressure areas that result from differential heating of land and water. During the hot months of April and May hot air rises over the Indian subcontinent, creating low-pressure areas into which rush cooler, moisture-bearing winds from the Indian Ocean. This is the southwest monsoon, commencing in June and usually lasting through September. Dividing against the Indian landmass, the monsoon flows in two branches, one of which strikes western India. The other travels up the Bay of Bengal and over eastern India and Bangladesh, crossing the plain to the north and northeast before being turned to the west and northwest by the foothills of the Himalayas. Natural calamities, such as floods, tropical cyclones, tornadoes, and tidal bores—destructive waves or floods caused by flood tides rushing up estuaries—ravage the country, particularly the coastal belt, almost every year. Between 1947 and 1988, 13 severe cyclones hit Bangladesh, causing enormous loss of life and property. In May 1985, for example, a severe cyclonic storm packing 154-kilometre-per-hour (95.7 mph) winds and waves 4 meters (13.1 ft) high swept into southeastern and southern Bangladesh, killing more than 11,000 persons, damaging more than 94,000 houses, killing some 135,000 head of livestock, and damaging nearly 400 kilometers (248.5 mi) of critically needed embankments. Annual monsoon flooding results in the loss of human life, damage to property and communication systems, and a shortage of drinking water, which leads to the spread of disease. For example, in 1988 two-thirds of Bangladesh's 64 districts experienced extensive flood damage in the wake of unusually heavy rains that flooded the river systems. Millions were left homeless and without potable water. Half of Dhaka, including the runway at the Shahjalal International Airport—an important transit point for disaster relief supplies—was flooded. About 2,000,000 tonnes (2,204,623 short tons; 1,968,413 long tons) of crops were reported destroyed, and relief work was rendered even more challenging than usual because the flood made transportation of any kind exceedingly difficult. A tornado in April 1989 killed more than 600 people, possibly many more. There are no precautions against cyclones and tidal bores except giving advance warning and providing safe public buildings where people may take shelter. Adequate infrastructure and air transport facilities that would ease the sufferings of the affected people had not been established by the late 1980s. Efforts by the government under the Third Five-Year Plan (1985–90) were directed toward accurate and timely forecast capability through agrometeorology, marine meteorology, oceanography, hydrometeorology, and seismology. Necessary expert services, equipment, and training facilities were expected to be developed under the United Nations Development Programme.

Rivers and Lakes

Bangladesh is a land of  rivers that crisscrossed throughout the mostly flat territories of the country. They include hundreds of brooks and a good number of big ones. The Ganges (Ganga) is known as the Padma below the point where it is joined by the Jamuna River, the name given to the lowermost portion of the main channel of the Brahmaputra. The combined stream is then called the Meghna below its confluence with a much smaller tributary of the same name. In the dry season the numerous deltaic distributaries that lace the terrain may be several kilometers wide as they near the Bay of Bengal, whereas at the height of the summer monsoon season they coalesce into an extremely broad expanse of silt-laden water. In much of the delta, therefore, homes must be constructed on earthen platforms or embankments high enough to remain above the level of all but the highest floods. In non-monsoon months the exposed ground is pocked with water-filled borrow pits, or tanks, from which the mud for the embankments was excavated. Throughout the country there are bils, haors and lakes that meet the need of drinking, bathing and irrigating water.

River systems

 

Ganges River Delta, Bangladesh and India

The rivers of Bangladesh mark both the physiography of the nation and the life of the people. About 700 in number, these rivers generally flow south. The larger rivers serve as the main source of water for cultivation and as the principal arteries of commercial transportation. Rivers also provide fish, an important source of protein. Flooding of the rivers during the monsoon season causes enormous hardship and hinders development, but fresh deposits of rich silt replenish the fertile but overworked soil. The rivers also drain excess monsoon rainfall into the Bay of Bengal. Thus, the great river system is at the same time the country's principal resource and its greatest hazard. The profusion of rivers can be divided into five major networks. The Jamuna-Brahmaputra is 292 kilometers long and extends from northern Bangladesh to its confluence with the Padma. Originating as the Yarlung Tsangpo River in China's Xizang Autonomous Region (Tibet) and flowing through India's state of Arunachal Pradesh, where it becomes known as the Brahmaputra ("Son of Brahma"), it receives waters from five major tributaries that total some 740 kilometers in length. At the point where the Brahmaputra meets the Tista River in Bangladesh, it becomes known as the Jamuna. The Jamuna is notorious for its shifting subchannels and for the formation of fertile silt islands (chars). No permanent settlements can exist along its banks. The second system is the Padma-Ganges, which is divided into two sections: a 258-kilometer segment, the Ganges, which extends from the western border with India to its confluence with the Jamuna some 72 kilometers west of Dhaka, and a 126-kilometer segment, the Padma, which runs from the Ganges-Jamuna confluence to where it joins the Meghna River at Chandpur. The Padma-Ganges is the central part of a deltaic river system with hundreds of rivers and streams—some 2,100 kilometers in length—flowing generally east or west into the Padma. The third network is the Surma-Meghna River System, which courses from the northeastern border with India to Chandpur, where it joins the Padma. The Surma-Meghna, at 669 kilometers by itself the longest river in Bangladesh, is formed by the union of six lesser rivers. Below the city of Kalipur it is known as the Meghna. When the Padma and Meghna join together, they form the fourth river system—the Padma-Meghna—which flows 145 kilometers to the Bay of Bengal. This mighty network of four river systems flowing through the Bangladesh Plain drains an area of some 1.5 million square kilometers. The numerous channels of the Padma-Meghna, its distributaries, and smaller parallel rivers that flow into the Bay of Bengal are referred to as the Mouths of the Ganges. Like the Jamuna, the Padma-Meghna and other estuaries on the Bay of Bengal are also known for their many chars.

A fifth river system, unconnected to the other four, is the Karnaphuli. Flowing through the region of Chittagong and the Chittagong Hills, it cuts across the hills and runs rapidly downhill to the west and southwest and then to the sea. The Feni, Karnaphuli, Sangu, and Matamuhari—an aggregate of some 420 kilometers—are the main rivers in the region. The port of Chittagong is situated on the banks of the Karnaphuli. The Karnaphuli Reservoir and Karnaphuli Dam are located in this area. The dam impounds the Karnaphuli River's waters in the reservoir for the generation of hydroelectric power.

During the annual monsoon period, the rivers of Bangladesh flow at about 140,000 cubic meters per second, but during the dry period they diminish to 7,000 cubic meters per second. Because water is so vital to agriculture, more than 60% of the net arable land, some 91,000 km², is cultivated in the rainy season despite the possibility of severe flooding, and nearly 40% of the land is cultivated during the dry winter months. Water resources development has responded to this "dual water regime" by providing flood protection, drainage to prevent overflooding and waterlogging, and irrigation facilities for the expansion of winter cultivation. Major water control projects have been developed by the national government to provide irrigation, flood control, drainage facilities, aids to river navigation and road construction, and hydroelectric power. In addition, thousands of tube wells and electric pumps are used for local irrigation. Despite severe resource constraints, the government of Bangladesh has made it a policy to try to bring additional areas under irrigation without salinity intrusion. Water resources management, including gravity flow irrigation, flood control, and drainage, were largely the responsibility of the Bangladesh Water Development Board. Other public sector institutions, such as the Bangladesh Krishi Bank, the Bangladesh Rural Development Board, the Bangladesh Bank, and the Bangladesh Agricultural Development Corporation were also responsible for promotion and development of minor irrigation works in the private sector through government credit mechanisms.

Flora and Fauna

Chittagong Hill Tracts, portions of the Madhupur Tract, and the Sundarbans (a great tidal mangrove forest in the southwestern corner of the country) are principal vegetation in Bangladesh. The wooded area amount to less than one-sixth of the total area. Broadleaf evergreen species characterize the hilly regions, and deciduous trees, such as acacia and banyan, are common in the drier plains areas. Commercially valuable trees in Bangladesh include sundari (hence the name Sundarbans), gewa, sal (mainly growing in the Madhupur Tract), and garan (in the Chittagong Hill Tracts). Village groves inslude fruit trees (mango and jackfruit, for instance) and date and areca (betel) palms. The country also has many varieties of bamboo. Bangladesh is rich in fauna, including nearly 250 indigenous species of mammals, 750 types of birds, 150 kinds of reptiles and amphibians, and 200 varieties of marine and freshwater fish. The rhesus monkey is common, and gibbons and lemurs are also found. The Sundarbans area is one of the principal remaining domains of the Royal Bengal tiger, and herds of elephants and many leopards inhabit the Chittagong Hill Tracts. Other animals living in Bangladesh include mongoose, jackal, Bengal fox, wild boar, parakeet, kingfisher, vulture, and swamp crocodile.

 

Geographic Features

Bangladesh is situated in South Asia between India and Myanmar. With an area of 148,393 sq. km and a population of approx. 130 million, it occupies the apex of the arch formed by the Bay of Bengal into which drain a large number of rivers and their tributaries crisscrossing the country and making it a very fertile delta. However, a dominant feature of life is the annual cycle of overabundance of water in the monsoon and its scarcity in winter. But the phenomenon changes dramatically during the winter months of November to May when the flows in the three major rivers- Ganges, Brahmaputra and Meghna - decrease considerably and most of the streams and channels almost dry up leading to shortage of fresh water for use in agriculture, fishery, navigation and industries as well as for domestic use. Normal floods are regarded as highly beneficial for revitalizing the cropland. The people have also learnt the coping strategies to minimize their adverse effects. Various measures have been taken in the past to cope with the effects of catastrophic floods but not always effectively. Comprehensive multi-national studies have been made during the recent years under the World Bank coordinated Flood Action Plan to find more effective ways to mitigating such floods without causing environmental hazards.

Seasons

Traditionally Bangladeshis subdivide the year into six seasons: Grismo (summer), Barsha (rainy), Sharat (autumn), Hemanto (Late autumn), Sheet (winter), and Bashonto (spring). For practical purposes, however, three seasons are distinguishable: summer , rainy, and winter.

Summer season in bangladesh

Throughout basanto, the weather warms up a bit each day until March 1, when the heat starts intensifying more rapidly. The soil turns a dusty khaki and then almost white. There are lightening and thunder storms and sometimes, icy lumps of hail crash down. The rivers dry out and are difficult to navigate. Grisma is also the peak time for the brick industry. Bricks are used for building and are a substitute for stone and gravel in Bangladesh. In the cities, the humid air is laden with dust, brick grit and auto fumes. The sun is a round red globe, beating down relentlessly. Everyone waits for the rains and the beginning of another cycle of seasons.

Bangladesh has a subtropical monsoon weather indicated by wide seasonal different versions in rainfall, moderately warm temperatures, and high humidity. During summer the sun shines hotly. The heat is terrible. Water goes dry. Ponds, canals, lakes and small rivers go dry. There is scarcity of water everywhere. The earth gets parched. People sweat at the slightest work and become tired and thirsty. People can not work at ease. Summer is also the season of various fruits. Various seasonal fruits ripe then. Three seasons are generally identified: a hot, humid summer from March to June; a cool, rainy monsoon period from June to October; and a cool, dry winter season from October to March. In normal, maximum summer season in bangladesh temperatures between 32°C and 38°C. May and april is the hottest months in most area of the country.

Summer Season in bangladesh

Bangladesh look very beautiful in summer season. In summer season and rainy season, the temparature raom around 28-35 degree celcius and there are heavy rainfalls in May, June and July. But it does not mean that there will be rain for 5/6 days in a Rowland can also go to bangaldesh in summer and rainy season. But you have to get ready for sudden rain. Most of these fruits—perishable in nature with high dietary value-are available during the specific season of production. Between these fruits; mango, jackfruit, litchi, banana, papaya, pineapple, watermelon, guava, lemon, star fruit, honeydew etc are available during the summer season in bangladesh. So, it is no surprise that summer in Bangladesh is called season of fruits—specially for mango, jack fruit, lichi and jam (black berry)—the common crowd favorites. In taste, flavor and structure, scores of most these fruits in Bangladesh are higher than similar fruits in other countries.

Rainy Season of Bangladesh 

In Bangladesh, which has both the world’s largest delta system and the greatest flow of river water to the sea, water rules the earth, and so the most important season of all is barsa, a time of lashing rains and tearing winds. In this season, 70 percent of the land is under water – water from rivers, the sea, rain, tidal waves, floods and the melting snows of the Himalayas. The rains are at first a welcome relief from the baking, dusty hot season. But as the rains continue, the land turns into a brown and watery mass, ever-changing in shape and texture. Fields and homes are flooded; people and animals  have to move to higher ground. Food is reduced to pre-cooked rice, dal and jackfruit that ripen at this time. During the rains, most villages are isolated, accessible only by boat. The people become self-sufficient and depend on each other rather than the outside world. The rain has turned stagnant water fresh again. Children leap naked into ponds. Women swim in sarees. Men dive in wearing sarongs. It is during the rainy season that Bangladesh’s main crop, jute, begins to ripen and is harvested. Farmers dive down to the roots to cut them. The stalks are placed on high ground to dry. Aside from the practical problems, the rains and water also inspire the poetry, art and songs of the people.

Bangladesh is a land of six seasons. The rainy in one of the them. It comprise the Bengli month of Ashar and Sravan. After a long spell of hot weather, the rainy season comes with showers to cool the earth. Our economy, culture and way of life are loosely related to it. The rainy season is caused by monsoon. The south west monsoon that a bole over Bangladesh from the Bay of Bengal brings many vapors with it. As a result, there occurs heavy rainfall during the monsoon in our country. During the rainy season the sky often remains overcast with thick black lauds that cover across the sky close to the earths suffers surface. Violent blasts of wind blow, lighting, flasher and thunder roar. 

The sun remains hidden behind of the clouds and it rains in torrents. Sometimes, there is continuous rain for days together. The low lying lands go under water and look like a vast sheet of water. The rainy season undoubtedly does must good to us. Name assumes a new appearance at the advent of the rainy season. The landscape appears green. The rainwater washes away the filth and purifies the surface of the earth. It lessons the intense heat of summer.

It makes our land alluvial, fertile and suitable for growing better crops. The atmosphere becomes clean and free of dust. The rainy season in not an unmixed blessing all the times. It has disadvantage too. During the season the roads in the countryside become muddy and slippery and as such people can not go from one place to other place foot easily. Sometimes heavy rainfall overflows the banks of the rivers and causes floods, which damage our crops, cattle, houses and properties. But whatever the demerits of the rainy season, it is the most important and useful season in our country. The prosperity and development of our agriculture, which is the heart of our economy largely, depend on the mercy of the rainy season. The people of Bangladesh always welcome it and like to enjoy its beauty.

 

Autumn season of bangladesh 

As September begins, the skies are blue and a cool wind blows. The land turns into a carpet of bright green rice shoots while the smell of drying jute invades the air. Flowers bloom, the rice  ripens and the harvest begins. Blue, gold and green are the colours of sarat – blue sky, golden sun and green vegetation from emerald to jade, pea to lime, shamrock to sea-green. In the green fields, white Siberian cranes, egrets and ducks hunt for food. Although the air is humid, there is a slight chill late at night.

It is the 3rd season out of six seasons. This season says in bangla time “Kartik-Aughrohaun ". Late-Autumn season times from a half of month in October to a half of month in December. It comes after autumn season. This time is covered by a gloomy air of all over the area. Late-autumn is only crops. So farmers are cutting down own crops in himself fields. It is the season dwell and more happily. They are always busy for harvesting in own crops. 

The early autumn season of Shorot comes in Bhadro and Ashwin. Shorot is characterised by clearing skies at the end of the Monsoons above, and below is the pungent odour emitted from golden jute collected and processed by farmers on every piece of available dry land. Then Hemonto swings through the fields of Bengal with cooler days in the months of Kartik and Ograhayon. Farmers take to clearing harvested fields to make way for winter crops and the iconic bucolic beauty of Bengal takes shape in both these seasons where the landscape is laced with Shaplas and Kashphools in full bloom.

Late Autumn Season of Bangladesh

 

Once the land has emerged from its watery grave, it is time to replant in new, fertile soil that is rich in nutrients. During this season, the land is at its luscious best. Festivals flourish to hail the harvest, the end of the floods, the coming of the new soil and the wonder of the rivers. The country’s troubadours are everywhere, dressed in bright clothes and singing for money. The land and its people come to life during hemanto, when the flowers bloom – jasmine, water lily, rose, magnolia, hibiscus and bougainvillea. By the season’s end, the air is no longer humid. Fresh scents replace the dry jute smell. 
Hemanto marks the start of the wedding season where receptions are held under red, blue, green or white tents.

Winter Season of Bangladesh 

 From mid-November to early January, the weather becomes more arid and less humid. The earth dries and dust forms. Warm clothes are pulled out. Young people play tennis, football, cricket and golf. Seet is also the season when people return to their ancestral villages, where they can experience once again the essence of Bangladesh – the harmony of man, beast, land, water and air.

Winter brings about a change in nature. At advent of winter, nature becomes dull and gloomy. The leaves of some trees whither at touch its icy hand. Days gradually become shorter and nights become longer. Cold wind blows continuously from the north. The morning often remains foggy and something nothing can be seen even at a little distance.
