Abstract: The Integrated Nitrogen in CAtchments model (INCA) was applied to the River Dee, Aberdeenshire, NE Scotland. To a first approximation themodel was able to simulate the annual mean streamwater NO3---N concentrations observed along the length of the mainchannel. This provided the basis for using INCA to subsequently explore the effects of N deposition and land use management on streamwater NO3---N concentrations and loads. On an annual timescale, the model predictions suggest that NO3---N concentrations will decrease by 5% following a 20% reductionin fertiliser application. Furthermore, model results also suggest that a 50% increase in N deposition will cause a 15% increase in the streamwater NO3---N concentrations. The utility of INCA as a tool for catchment management is discussed, current limitations are highlighted and possible improvements are suggested. [ABSTRACT FROM AUTHOR]
