Unsteady State Groundwater Flow in Semi-Finite Artesian Aquifer due to Water Level Changes in Bounding Channels
Publication Date : 04-05-2020
In this paper, the flow of ground water induced by variation in water level in two channels bounding a confined aquifer was studied. The water level in each channel varies gradually over time and can be defined by exponential mathematical functions. Analytical solutions were sought to the problem using the Laplace transform method. The values of head were obtained in error functions which can be evaluated at various times and places in the aquifer. A numerical example problem was given in which head values at various places in the aquifer were computed at varying time intervals. Similar results were also obtained for various values of a delay constant introduced in the study and these were compared.
