ABSTRACT
It is widely accepted that groundwater and surface water are not isolated components of the catchment water balance and that their interaction is important to stream ecology, water quality and water quantity. A quantitative understanding of the interaction between surface water and groundwater is therefore crucial for sustainable management of water resources. Because surface water-groundwater (SW-GW) interaction is inaccessible and difficult to manipulate, fully integrated models play an important role in exploring the underlying physics, and the geological and the hydrological factors which control the interaction between these two components. In this talk, recent examples of how physically based models can help to understand hydrological processes are presented. Also, the combination of state of the art inverse modeling approaches with a model simulating the interaction between vegetation, surface water and groundwater is presented. Some final conclusions are drawn.
