Ein integratives Planungsinstrument für das Hochwasserrisikomanagement

Abstract

Aspects of water and flood management are often too little or too late included into the spatial planning process. At the same time aspects of geodata infrastructure and flood related data and information has to be considered as a crucial interface in a concept for integrated planning. Against this background a planning instrument on the scale of a river basin was developed—the catchment related development plan (gGEP). The concept includes also the interfacial requirements to technical and computer based tools like Planning or Decision Support Systems. The overarching aim of this planning instrument is to integrate flood relevant issues in order to minimize the flood risk or not to increase it further respectively. The catchment related development plan can be considered as an important pre-stage for setting up flood risk management plans according to Art. 7 of the EU Flood Risk Management Directive. The very urban area of the City of Hamburg and rural parts of Lower Saxony in Germany serve as case study areas for the concept.
