Numerical Solution of 1D Boussinesq Equation for Water Table Fluctuation between Drains in Response to Recharge and ET in A Sloping Aquifer

Surjeet Singh, NC Ghosh, RP Pandey, RV Galkate, T Thomas, RK Jaiswal


A non-linear Boussinesq equation is solved using finite-difference technique for the estimation of water table variation subjected to recharge and ET in a sloping aquifer. The aquifer is subjected to exponentially declining recharge and ET as a function of water table height below the land surface. The proposed numerical solution gives results in close match with the already existing mathematical solutions. Inclusion of ET into the flow system in combination with recharge results in wider drain spacing and consequently results in economy. As the proposed numerical solution accounts for both recharge and ET, it is very general, accurate and of great interest to scientists, theoreticians and policy makers in checking the numerical values related to the field problems of waterlogged and saline lands.
