Infiltration in a recharge dam reservoir using a green and ampt model and a water budget approach

Abstract EN

Two approaches are used to study infiltration in a recharge dam reservoir.

The first is based on the Green and Ampt infiltration equations while the second uses a water budget for the reservoir.

The two models gave comparable estimates of the cumulative infiltration depths up to the arrival of the wetting front at the water table.

The average daily infiltration rates predicted by the infiltration model were more consistent than those obtained using the water budget method.

The infiltration approach is also more physically-based and can be incorporated in a recharge model.
