This study documents the development of a link between a geographical information system (GIS) and a non‐point source pollution model. The GIS ARC/INFO was linked to the agricultural non‐point source pollution model and ORACLE data sources. Application of the system is demonstrated using the Bedford‐Ouse catchment as a suitable case study. Water quality impacts are predicted from source data describing topography, soils, land use and river network. The model results were in agreement with observed nitrate concentrations at the catchment outlet, and more appropriate data sources are considered to be the main priority for improving model predictive ability. Management scenarios were established to assess the impact of changing agricultural management practices on predicted water quality. The approach has significant potential for the management of agricultural pollution in the UK.
