| Zusammenfassung |
| Despite the great scientific and technological advances in flood hydrology,
everyday engineering practices still follow simplistic approaches that are
easy to formally implement in ungauged areas. In general, these "recipes"
have been developed many decades ago, based on field data from typically few
experimental catchments. However, many of them have been neither updated nor
validated across all hydroclimatic and geomorphological conditions. This has
an obvious impact on the quality and reliability of hydrological studies,
and, consequently, on the safety and cost of the related flood protection
works. Preliminary results, based on historical flood data from Cyprus and
Greece, indicate that a substantial revision of many aspects of flood
engineering procedures is required, including the regionalization formulas
as well as the modelling concepts themselves. In order to provide a
consistent design framework and to ensure realistic predictions of the flood
risk (a key issue of the 2007/60/EU Directive) in ungauged basins, it is
necessary to rethink the current engineering practices. In this vein, the
collection of reliable hydrological data would be essential for
re-evaluating the existing "recipes", taking into account local
peculiarities, and for updating the modelling methodologies as needed. |
