According to Floods Directive, the Member States shall, at the level of the river basin district or unit of management, prepare flood hazard maps and flood risk maps at the most appropriate scale for the areas identified under Article 5(1).

The Information Management and Geographical Information System Expert Group (IMGIS EG) deals with activities related to data collection and maps.

daNUbs was a mulitnational EU research project carried out under the leadership of the Technical University of Vienna. The results from this project include estimates of nutrient inputs into the river network (MONERIS), as well as an assessment of the loads of nitrogen, phosphorus and silica transported via the river network. These results indicate that the nutrient status in the Black Sea has significantly improved since the 1980s.

The nutrient levels, notably phosphorus and nitrogen, found in the Danube River and its major tributaries hold significant international importance. This is because they directly contribute to the phenomenon of eutrophication in both the river itself and the Black Sea. Historical trend analysis of nutrient river loads over the past decades shows a significant reduction in the transported nutrient fluxes to the Black Sea. Overall nutrient emissions declined by 30% (nitrogen) and 50% (phosphorus) in the last 15 years. However, the current long-term fluxes are still considerably higher than those of the early 1960ies which represent river loads under low pressures, indicating a further load reduction potential that might be exploited for the benefit of the Black Sea. Nevertheless, in the last 5-10 years the measured loads are rather low and close to the Black Sea targets indicating significant water quality improvement.
