Abstract:
The suitability of the widely used existing solution for calculating groundwater mound due to artificial recharge from rectangular
areas is examined for its applicability to unconfined aquifers, and this solution has been found applicable only to confined aquifers. The
solution applicable for confined aquifers is derived and shown equivalent to the existing solutions. A computationally simple function is
proposed for accurately approximating the integral appearing in this or existing solutions. A procedure involving analytical approximation is
outlined for using this solution for unconfined aquifers. A method to calculate groundwater mound height in unconfined aquifers due to
arbitrarily varying temporal recharge (percolation) is also proposed. It is hoped that the proposed methods would be of help to field engineers
and practitioners.
