• The ArcInfo Geographical Information System (GIS) was used to develop spatial databases for recording spatial data. The databases developed in this study provide a graphic and mapping display interface to assist the management of the Namoi Basin in New South Wales, Australia. In addition, the databases are used in the investigation of the impacts of spatio-temporal changes in landuse/management on hydrologic processes from catchment to basin scales. Climate, stream flow, and water quality data are being incorporated into the ArcInfo dataset to drive and test hydrologic models.
