New System Improves River Basin Health Assessment for Water Framework Directive
Scientists have recently developed a new computer modeling system that will improve the way in which river basins are assessed for the European Water Framework Directive.
The system has been named the Elbe decision support system, (Elbe-DSS), after the river it was initially developed for assessing, the River Elbe, one of the largest in Europe.
The system will specifically monitor the following elements of river catchment:
One of the strengths of this system is that it will help cross-border collaboration in tackling river management objectives. The system can be intelligently manipulated in order to assess the likely impacts of likely changes in variables affecting the catchment area, such as reforestation and increased/decreased fertiliser input.
Having tested theory against practice, it has proved to be reliable in predicting nutrient levels across the whole river basin. Because the system can be applied at various spatial scales, it means that approaches can be taken at specific locations across the modeled area in an efficient way. It also allows management actions to be ranked in importance according to modeled assumptions about future environmental and demographic changes.
The system is free and available from the German Federal Institute of Hydrology, (although the website is currently under construction and written in German).
