The nutrient emissions from point and diffuse sources were estimated for 388 subcatchments of the  Danube river basin for the period 1998-2000 with the model system MONERIS. The model distinguishes between six diffuse pathways and point source emissions from waste water treatment plants and direct industrial discharges. It was estimated that the total nitrogen emission into the Danube river system amounts about 690 kt/a in the period 1998 to 2000, with 80 % from diffuse sources. For phosphorus the emissions accounted for the same time period 67.2 kt/a, with a share of diffuse sources of 64 %. The comparison between measured and observed loads in the investigated subcachments shows a mean deviation of 21 % for nitrogen and 30 % for phosphorus. The spatial resolution of the emission calculations allows the identification of regional hot spots and the derivation of specific regional measures for emission reduction.
