The research activities at the section ihwb are fundamental research in the field of hydrology and applied research in the field of water management.

The focal point in hydrological fundamental research is the mathematical modelling of catchment areas with special consideration of anthropogenic influences. Urban and agricultural areas and their interdependencies with water balance and balance of matter are of particular interest as well as the integration of sub-models of the several scopes of a catchment area into an integrated model.

The main focus in water management is the operation of large dams. Models and methods are being developed to optimise the operation of storage systems with multi-purpose utilisation. In this connection the improved ecological function of large dams has a prominent part for several years.

Apart from the application of simulation tools the development of optimization procedures is an important part. In this context especially generally applicable optimization procedures based on simulation and derivative free methods like genetic and evolutionary algorithms are refined and further tested. In hydrology these are employed in the autocalibration of models. In water management they are used to optimize the structure and the management of water supply systems. In this field too an essential prerequisite for a successful utilization of optimization procedures is the transparent embedding in computerized systems to facilitate the decision making. ihwb contributes to the acceptance and efficiency of hydrological models by development and experimental application. Particularly in the field of integrated flood risk management ihwb has expert knowledge of the development of such systems as basis for open planning processes.

Main precepts of the research activities are a close connection among research and teaching as well as disclosure of research findings by the means of publications, conference papers and the provision of software models and algorithms.
