Padma Multipurpose Bridge Project

Figure 3-17: Flood prone areas in the Project area3.1.7 Groundwater Resources37. The Project area has a huge groundwater potential and groundwater occurs both inunconfined and confined conditions. Groundwater is widely used for drinking as well as for irrigationpurposes in the Project areas. The water level from flood plains in the shallow aquifers is almost closeto ground level, while depth to the water table from the deeper aquifers ranges from 3 to 8m. Basedon data collected from Bangladesh Water Development Board (BWDB), depth to the groundwaterlevels on the left bank varies from 0.13 m to 8.23m; and on the right bank varies from 0.07 to 5.61m.3.1.8 Bathymetry38. A 14 km long bathymetry survey was conducted in 2008 and September 2009 to update thebed information near the bridge. Another recent bathymetric survey was carried out at the Arial Khan3-21
