Shallow subsurface drainage for managing seasonal flooding in Ganges floodplain, Bangladesh
The impact of shallow subsurface drainage was investigated as a pilot study on a 0.13 ha plot of a farmer’s field located in Batiaghata, Khulna District, Bangladesh, in the floodplain of the Bay of Bengal. The drainage design differed from traditional subsurface tile drains in two respects: (i) the depth of drains was shallow (30 cm); and (ii) the design did not include a sump and accessories such as pumps (drainage outlets were tidal).
