The relationship of ground water to alluvium in Dinajpur and Rangpur, East Pakistan.

The University of Arizona. 1968

East Pakistan ground water occurs in complex alluvial deposits. Practically no work has been done to determine the aquifer properties and ground water conditions of the sediments, the determination of which is prerequisite for the efficient exploitation of the resource. In the present study, an attempt has been made to determine aquifer properties and ground water conditions in Rangpur and Dinajpur by geologic interpretation and lithologic analyses in conjunction with limited pumping test analyses supplemented with water table study. It is difficult to correlate alluvial sediments from one well to another; nevertheless, they maintain a general uniformity when the entire study area is considered. This fact is apparent also from water table contour maps which indicate homogeneity of the underlying aquifer. The coefficient of transmissivity obtained by lithologic and by pumping test analyses ranges from 7 x lO^4 to 13 x lO^4 gpd/ft, having an average of about 10 x l0^4 gpd/ ft for the upper saturated 250 feet of the aquifer. The average permeability and specific yield of the aquifer are found to be about 400 gpd/ft^2 and 0.20, respectively.
