**7. Conclusions**

The application of the SWAT model in the Reka and Dragonja catchment has demonstrated that SWAT is able to represent the hydrological behaviour of this heterogeneous catchments and rivers. Within the constraints of the available data the model was able to represent the sediment and nutrients loads, concentrations and cumulative distributions. However, there are a number of issues that the model results can demonstrate as important in the diffuse water pollution control with agri-environmental measures.


in the model, which can lead to appropriate modelling of nutrients pathways and to account for the nutrient lag times in the groundwater.


At the end of this chapter we would like to increase awareness that model results and their interpretation by the modeller must lead to constructive discussion, which aims to achieve and maintain good water quality in research catchments, which is the objective of the Water Framework Directive and other legislation related to water.
