**The equation representing the groundwater mound beneath a rectangular recharge area is given by:**

**where h _{m} is the maximum height of the mound; h_{i} is the initial height of the water table; w is the recharge or percolation rate; K is the hydraulic conductivity; t is the time of interest; L and W are the length and width of the rectangular recharge area, and ε is the specific yield of the aquifer. S* is an integral equation given by:**

**This equation is estimated in the calculator by using a table of values given by Hantush (1967).**

**You can also perform mounding calculations with graphical display using:**
