2-DIMENSIONAL MODELING OF WATER-TABLE FLUCTUATION IN RESPONSE TO LOCALIZED TRANSIENT RECHARGE

An analytical solution of the linearised Boussinesq equation is presen ted and used to predict the spatio-temporal variation of the water tab le in a finite aquifer system in response to a transient recharge from an overlying rectangular basin. The boundary conditions of the finite aquifer are taken as fixed heads, which would apply when the aquifer system is surrounded by open water bodies. Application of the solution is illustrated with the help of a numerical example. The results woul d also have applications in studying stream-aquifer interaction in the presence of transient recharge.
