Modeling surface water



The IAHS symposium New Directions in Surface Water Modeling was held May 15–17, sponsored by the International Commission on Surface Water. The nine symposium sessions were on rainfall fields, physics-based hydrological models, floods, rainfall-runoff models, droughts, geographic information systems (GIS), decision-support systems, and expert systems. There were 38 oral and 11 poster papers from 24 countries.

Using GIS as a tool in hydrology has great potential for improving the spatial description and modeling of basin geomorphology and hydrological parameters. Radar- and satellite- based studies of rainfall fields show significant advances in the estimation and shortterm prediction of rainfall in time and space.
