RIVER SURMA

River of Life Surma River

The Surma River is a major river in Bangladesh. It rises in northeast Indian region of Assam, flows through the city of Sylhet, goes on to feed the River Meghna, one of the three major rivers of the Ganges Delta. The Meghna River flows south past Dhaka and ultimately enters the the Bay of Bengal. The total journey from source to mouth is 946 km. Throughout its course, the river is known by many names. From its source in the Manipur Hills it is called the Barak River. At the border with Bangladesh, where the river divides, the northern branch is called the Surma River and the southern the Kushiyara River. The Surma is also known as the Baulai River after it is joined by the Someswari River. When the Surma and the Kushiyara rejoin above Bhairab Bazar, the river is known as the Meghna River. The Surma is prone to flooding in the monsoon season between the end of May and the middle of October. Nearly 80% of the annual average rainfall in Sylhet occurs between May and September. Conversely, during the dry season, from November to April, the Surma can run dry leaving the region with severe water shortage issues as shown in the photograph below left. This area of northeast Bangladesh is characterised by shallow basins known as haors and beels (oxbow lakes) which fill with flood waters during the monsoon season and become important wildfowl habitats. The highly distinctive landscape was caused by tectonic subsidence primarily during the earthquake of 1762. Sylhet region falls within the most earthquake prone zone of the country. During the last 150 years three major earthquakes have occurred in this area. But since the last catastrophic earthquake occurred in 1918, very few people remember it. Experts clearly say a strong earthquake affecting a major urban centre like Sylhet may result in damage and destruction of massive proportions and may have very long term consequences for the entire country. Like most major urban centres in Bangladesh, Sylhet has grown tremendously in the last few decades due to unabated migration from the smaller towns and rural areas. The city has developed in an unplanned way with little consideration for proper town planning norms. About 80 per cent of the city’s buildings have been constructed without following the authorised building code.
