Drainage of Sloping Lands with Constant Replenishment

Abstract

An analytical solution is derived using the Boussinesq equation to describe an unsteady rising water‐table profile in an aquifer lying over a mildly sloping impervious bed in response to constant replenishment. A Hele‐Shaw model is used for experimental verification of the analytical solution. Reasonably close agreement is found in the computed and observed phreatic surfaces. The analytical solution can be used with reasonable accuracy for the design of subsurface drainage in sloping phreatic aquifers.
