| Zusammenfassung |
| Hydrological models for flood management are components of flood risk
management, which is the set of actions to be taken to prevent flood
disasters. It is a cyclical process: initiated by occurrence of an extreme
flood it leads through the reconstruction and rehabilitation phase to risk
assessment and project planning and implementation, and finally to operation
and preparedness for a next extreme flood when the cycle starts again. We
subdivide the tasks of flood management into two consecutive parts: planning
and operation, which basically require different kinds of hydrological
models. For planning, real time runoff is not needed, one works with design
scenarios. For this task models should be used appropriate to the tasks at
hand, which reflect characteristics of landscape as well as of hydrological
scale. For operation, hydrological forecast models are needed which have to
meet a different set of conditions. In this paper, requirements for
hydrological models as functions of application, geology and topography, and
of area size are surveyed and classified, as a first approach for guiding users
to the correct type of model to be used in a given location. It is suggested
that one always should start flood
modeling with an analysis of local conditions and select or develop task and
locality specific models. |
