Abstract
The Surma River in Bangladesh sustains the livelihoods of millions residing along its banks and serves as a vital resource for activities such as fishing and bathing. Since the water quality of the river is negatively impacted by multiple factors including waste disposal, these practices are not safe for people to continue.
Seeing as the Tanguar Haor sits in the floodplain of the Surma river and, the river is polluted with waste and plastic from cities and villages along the riverbanks, the trash that is discarded into the Surma can eventually end up in the Tanguar Haor and pollute the water and soil.
The Tanguar Haor is a wetland located in the Sunamganj district, west of Sylhet, and is very low lying land. Due to the low lying nature of the haor it is inundated for around 7 to 8 months a year. It is highly affected by rainfall and floods since it lies at the foot of the Meghalaya mountains. When heavy rains occur upstream or in the catchment areas of these rivers, the water flows downstream into the delta, causing rivers to overflow their banks.
The land’s lack of elevation makes it difficult for floodwaters to recede quickly, leading to prolonged inundation.
This graduation project tackles living in the ever changing wetlands of Bangladesh. A project about flood resilience and circularity and the intersectionality of several problems they face: lack of sanitation, waste and water pollution and frequent flooding.
The design proposal takes the strengths of the current settlement and way of living and turns them into a more liveable, circular and flood resilient village.
