5.2.2. Flow of groundwater and water table of the study area
Fig. 1 has shown the study area which is situated on the side of the Bay of Bangla. It is indicated by different authors (Alam, 1989; Curray, 1991; Zakaria et al., 2015) that the water level is lower in the coastal areas of Bangladesh. The water table has found in a higher depth of 28.5m in the study area (Table 1). The water level of Well No. 4 has found moderate depth, but the water level of the Well No. 2 has been found in higher depth. The groundwater flow of Bangladesh has been found to the north to south. The safe water-bearing zone has found in higher depth for the topographic variation surroundings of the study area (Fig. 3(A)) and (Fig. 2(a) and Fig. 2(c)).
