✦ Synopsis
Mathematical models are being used to develop a decision support system for integrated management of the Ythan catchment in NE Scotland. One component of this has involved the development of a distributed catchment-scale hydrological model. The model is based on subsurface ¯ow routing and calculates the contribution to stream ¯ow from each 50 m  50 m cell in the 548 km 2 catchment. It uses two topographic parameters, slope and distance to stream following the main line of ¯ow, and ®ve physical parameters. The topographic analysis and distributed ¯ow accumulation are performed by linking the single cell model with a geographic information system. Preliminary results from a three-year simulation of daily ¯ows indicate that the model successfully predicts the main characteristics of the catchment ¯ow.
