Understanding of Ground Water-Surface Water Relationship through the Analysis of Ground Water Flow System of Part of Bengal Delta
Author(s): Sheikh Mahabub AlamSheikh Mahabub Alam
The study area is part of Ganges-Meghna Deltaic Plain of the largest in the world, enjoys monsoonal climatic conditions. The main aquifer (aquifer-1) is made up of unconsolidated mostly sandy materials with some finer sediment and is gradually coarsening downwards with gravels and pebbles at the bottom. Hydraulic characteristics indicator confined conditions for the smaller eastern part while leaky-confined conditions prevail elsewhere. The ground water elevation is highest in the east-central (Comilla town) region and this is primarily due to maximum withdrawal and partly due to partial blockage of ground water flow by the north-south trending Lalmai Hills located to the west of Comilla town. The complicated flow net structure and its behaviour suggest that all perennial rivers maintain direct hydraulic continuity with Ground Water. Flow-net analysis reveals that most rivers in its d..
