Kurzfassung englisch:
The MONERIS emission model, which was developed in Germany, has been applied to the Austrian territory
with a resolution of 367 sub-catchments of 10 to 1000 km2 size for calculation of nitrogen and phosphorus
emissions via different pathways and retention and losses of nutrients in the river network. Enhancement and
adaptation of the model approach has been necessary in order to improve model performance in alpine
catchment and in order to relate calculations to the typespecific Austrian environmental quality standards
(EQS), which - for nutrient parameters - are defined as 90 % percentiles of the concentrations of NO3-N and
PO4-P in the rivers. Due to implemented improvements, a good model performance has been achieved for
most of the considered catchments. Modell results for N and P facilitate (i) a demonstration of regional
relevance of sources and pathways of nitrogen and phosphorus emissions, (ii) information on exceedance of
EQS of NO3-N and PO4-P in rivers and creeks which are not regularly monitored, (iii) the development of a
well-designed river monitoring systems and (iv) scenario calculations, which show the effectiveness of
measures on local water quality and riverine nutrient transport across the country borders.
