Implementation of a Distributed Hydrologic Model within Geographic Resources Analysis Support System (GRASS)

Abstract

A number of strategies in conjunctive use of hydrologic models and GIS are outlined. By using data base structure and functions of GRASS GIS this particular effort follows the "full integration" strategy by reprogramming CASC2D distributed parameter hydrologic model within GRASS GIS. Several advantages gained in fully integrating these two components are highlighted. While major features of the hydrologic model CASC2D are briefly described, the input requirements and output options in relation to GRASS are discussed in more detail. Some general issues in conjunctive use of hydrologic models and GIS are also addressed.
