Abstract

A GIS-based Decision Support System (DSS) was developed to select the appropriate interpolation
technique used in studying rainfall spatial variability. The DSS used the ArcView GIS platform by
incorporating its spatial analysis capabilities, the programming language "AVENUE", and simple statistical
methods. The system consists of a series of modules and can be applied in spatial studies of
other hydrological parameters. A test case from the country of Switzerland is used to demonstrate the
applicability of the system. This should aid in better input to hydrological models.
