Abstract:
Aquifer parameters are very important for the solution of ground
water flow problems. The knowledge of aquifer parameters to predict the water table
variations and the possibility of conjunctive use. A field study was conducted in three
open wells tapping laterite, clayey and alluvial formations to determine the aquifer
parameters from pumping test data. The aquifer parameters of each well were
determined by the time-drawdown analysis using Jacob’s method. The alluvial
formation showed high value of hydraulic conductivity than that of laterite and clay
formations due to its permeable nature. The specific capacity of the aquifer
determined using average head method and Slitcher’s method showed an uneven
variation, which may be due to the heterogeneous nature of the formation. Regression
analysis of drawdown and recuperation curves was done for three wells. Drawdown
and recuperation increase with time. Knowledge of these parameters is helpful in
deciding proper utilizing of ground water for irrigation and other purposes.
