Operational systems for water management under extreme climatic conditions

The storms, extreme heavy rain falls and floods of the last time require water management more than ever for extreme conditions and long-term climatic changes. Hence new strategies are needed to secure requirements of society and environment. On an international level comparable results and intergovernmental water management is required which means to learn from each other experience. To ensure sustainable water management strategies a holistic approach is emphasized. The bases of a modem water management system are computer based Decision Support Systems (DSS) including computer simulation tools with active graphical user interface. By using of modem mathematical solutions (e.g. Fuzzy-systems, GIS, Neuronal Networks) the prognosis of water level and flood prevention and control is possible. A DSS requires a coupled analysis of all kinds of data to describe the long-term scenario of global and local changes. To get measurable results benchmarks are defined to evaluate performance of the developed simulation tool. Water management needs will be set into a socio-economic context.
