Linearised Boussinesq equation for modelling bank storage – a correction

In a recent paper, Govindaraju and Koelliker used the Boussinesq equation to describe the horizontal one-dimensional flow of water into an unconfined aquifer from a channel. An improved analytical approach is suggested both for constant and time dependent boundary conditions using the linearised Bou...

Description
Summary:In a recent paper, Govindaraju and Koelliker used the Boussinesq equation to describe the horizontal one-dimensional flow of water into an unconfined aquifer from a channel. An improved analytical approach is suggested both for constant and time dependent boundary conditions using the linearised Boussinesq equation. The results are compared with those of Govindaraju and Koelliker and the numerical solution of the Boussinesq equation. The new analytical approach yields better results, especially for positive fluxes from stream to aquifer, and is as easy to apply as the method of Govindaraju and Koelliker. When the flux is negative more theoretical studies are needed. © 1997 Elsevier Science B.V. All rights reserved.
