Sažetak
The study was conducted on the river Sutla, which is a natural border between the Republic of Slovenia and the Republic of Croatia. This study aims to show the SWAT model results of diffuse and point source pollution risks in order to implement measures that could avoid a possible water quality deterioration, which is one of the biggest challenges in water management of this area. In the case of transboundary river basin, the challenge is even greater because of a range of factors related to diversity of water management, backgrounds, approaches, interests and development scenarios for the defined area. The performance indicators of the modelled daily flow (R2, NSE and PBIAS) during calibration period of 2009-2014 were 0.59, 0.61 and - 10.58 and for the validation period we re 0.54, 0.54 and 0.59, respectively. Monthly calibration objective function statistics NSE for sediment concentration, nitrate nitrogen load and mineral phosphorus load were defined as 0.72, 0.65 and 0.41, respectively. Results show that point sources in normal conditions contribute very small share of N (3.2%) and P (7.2%) on average daily basis.
