| Zusammenfassung |
| Riparian zone delineation is a central issue for managing rivers and
adjacent areas; however, criteria used to delineate them are still under
debate. The area inundated by a 50-yr flood has been indicated as an optimal
hydrological descriptor for riparian areas. This detailed hydrological
information is usually only available for populated areas at risk of
flooding. In this work we created several floodplain surfaces by means of
two different GIS-based geomorphological approaches using digital elevation
models (DEMs), in an attempt to find hydrologically meaningful potential
riparian zones for river networks at the river basin scale. Objective
quantification of the performance of the two geomorphologic models is
provided by analysing coinciding and exceeding areas with respect to the
50-yr flood surface in different river geomorphological types. |
