Abstract

Close to a river the traditional groundwater Dupuit assumption of horizontal flow does not hold. In order to treat the problem accurately one would need to use a 3-dimensional numerical model with small cells in the vicinity of the river. Presented here is an analytic approximate way to avoid this extra complication and still describe accurately the exchange flow between the stream and the aquifer.
