Policy makers are confronted with the question of how to combine sustainable flood protection and floodplain rehabilitation in the best possible way. Both topics deal with spatial planning aspects in a range of scales. This question was the starting point for the development of an evaluation method within the IRMA/SPONGE project INTERMEUSE, illustrated on the basis of assumed flood protection strategies in the Meuse river basin (the sponge strategy, the retention strategy, and the floodplain lowering or winter bed strategy). The integration of flood protection and floodplain rehabilitation can be performed on two scale levels that are interrelated: on the regional level the focus is on (large parts of) an entire stream basin; on the local level specific site conditions are taken as starting point. Ecological aspects under study are spatial cohesion of habitats as identified by species population persistence modelling (regional, longitudinal level) and required habitat quality for carabid beetles and for meadow vegetation gradients as assessed by correspondence analysis (local, transversal level). The carabid beetles are taken as indicative for the ecological integrity of the river bed, the meadow vegetation for that of the floodplain. A unifying concept in the evaluation of ecological integrity is the ecological minimum: the critical boundary or minimum level of habitat conditions for a potentially good ecological functioning. It is the least acceptable state for a river ecosystem that is still functional to some extent, compared to a natural river ecosystem. The results of this study show clearly that there is a good chance to combine floodplain rehabilitation aims with flood protection activities, both on a local and on an international scale. Although ecological effect assessment and ecological optimizing (referring to a natural reference state) remain basic, additionally the assessment of the ecological minimum helps to define design strategies for integrated flood protection, especially in situations where there is an opportunity for river rehabilitation.

The water ecotope classification (WEC) has been developed as a tool for integrated water management in the Netherlands. The classification is based on abiotic processes, such as morphodynamics, hydrodynamics and land use, that determine the appearanceof the water systems. Abiotic conditional factors were selected to represent these processes in the classification, due to their stability, measurability and manageability. For lakes, canals, rivers, transitional waters and coastal waters, system-specific classifications have been made, each resulting in 20-80 spatially defined, abiotic and biotic more or less homogeneous units. Each ecotope is described in terms of its position in the landscape, abiotic conditions and processes, ecological processes and dominant biotic groups. Ecotopes are mapped every eight years in the large water bodies on a scale of 1 : 10 000. Ecotopes are used in national policy analysis and regional studies to portray alternative spatial configurations, and they serve as input for hydrological and ecological models to analyse effects on water levels and habitat suitability. The success of ecotopes is due to the fact that they provide a common language for different disciplines, since the concept is used both by hydrologists and ecologists as well as by scientists and decision makers.
