Internal consistency as guiding principle for integrated system modelling J.-L. de ~ o k ' , K. van der wall & H. G. wind' I Department of Water Management, Faculty of Engineering Technology, Twente University Abstract After the Elbe flood event of August 2002 ongoing river engineering works have been placed in the center of attention. Proposed actions include dike displacement, floodplain excavation, and the retention basins. Flood risk, however, is not the only concern for water managers. Along the Elbe River several natural reserves can be found that form an essential habitat for rare fauna and vegetation. It is not yet clear how the hydromorphological consequences of river engineering works will affect the ecology of the floodplains. The formulation of an optimal management strategy requires indepth understanding of the interaction of these measures with the socialeconomic, ecologic, and physical processes at different spatial and temporal scale levels. Therefore, the German Federal Instit
