ABSTRACT

Flood forecasting systems form a key part of preparedness strategies for disastrous Ÿoods and provide hydrological services, civil protection authorities, and the public with information on upcoming events. Provided the warning lead time is suf¥ciently long, adequate preparatory actions can be taken to ef¥ciently reduce the impacts of the Ÿooding (Penning-Rowsell et al., 2000; de Roo et al., 2003).
