Nutrient Emissions into River Basins of Germany | Umweltbundesamt

The model ONERIS (MOdelling Nutrient Emissions in RIver Systems) was developed and applied to estimate the nutrient inputs into river basins of Germany by point sources and various diffuse pathways. the model is based on data of river flow and water quality as well as a geographical information system (GIS) which includes digital maps and extensive statistical information.
