Water table fluctuation due to transient recharge in a 2-D aquifer system with inclined base

Recharging of aquifers due to irrigation, seepage from canal beds and other sources leads to the growth of water table near to the ground surface causing problems like water logging and increase of salinity in top soils in many regions of the world. This problem can be alleviated if proper knowledge of the spatio — temporal variation of the water table is available. In this paper an analytical solution for the water table fluctuation is presented for a 2-D aquifer system having inclined impervious base with a small slope in one — direction and receiving time varying vertical recharge. Application of the solution in estimation of water table fluctuation is demonstrated with the help of an example problem.Notations A length of the aquifer L] - B width of the aquifer L] - D mean depth of saturation L] - e specific yields - h variable water table height L] - K hydraulic conductivity LT ^–1] - P(t) transient recharge rate LT ^–1] - P ₁+P _o initial rate of transient recharge LT ^–1] - P ₁ final rate of transient recharge LT ^–1] - q slope of the aquifer base in percentage - r decay constant T ^–1] - t time of observation T] - x, y coordinate axes - x ₂–x ₁ length of the recharge basin L] - y ₂–y ₁ width of the recharge basin L]
