This report focusses on the application of the NL-CAT model, a combination of the SWAP (unsaturated zone/groundwater-flow), ANIMO (nutrient processes and flow), and SWQN (surface water quantity) and the NuswaLite surface water quality model (SWQL), on 6 European catchments (Vecht, Enza, Ouse, Vansjo-Hobol, Zelivka and Odense catchments). A description of the model setup and discretisation of all catchments is presented. Soil balances are presented in terms of nutrient input, nutrient off-take by crops, nutrient turnover processes like accumulation in soils (mineral and organic), denitrification and nutrient discharges to deeper groundwater and surface waters. Finally retention in the surface water is calculated for each catchment on catchment scale. Furthermore the results of a scenario analysis on two catchments, Enza and Zelivka, are presented.
