Simulating Dry Weather Groundwater Flow in Temperate Climates using BILAN

Abstract

The BILAN model (version 1.7) has been developed for assessing water balance components of a catchment using a monthly step. The structure of the model is formed by a system of relationships describing basic principles of the water balance on the land surface, the zone of aeration, including the effect of vegetation cover, and groundwater. Air temperature is used as an indicator of energy conditions, which affect significantly the water balance components. The model is run for two sets of parameters and the results are obtained. The results are in accordance with expected results.
