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 ...

Abstract: Steady‐state flow with replenishment to horizontal tube drains in a two layered soil has been simulated in a vertical Hele‐Shaw model. Comparison of analytical solution of Toksoz and Kirkham on the simulated flow system ...

Abstract: The assumption of considering the lower layer to be impervious, if its hydraulic conductivity is one‐fifth or less from that of the upper layer, leads to erroneous results. Many research workers have attempted solutions ...
