| Zusammenfassung |
| The extreme summer flood in the Elbe River watershed
initiated a debate on the role of forest conversion and afforestation as
measures for preventive flood protection. To quantify the effect of forest
conversion and afforestation on flood runoff from catchments reliable model
calculations are essential. The article overviews the present state of our
work and provides an example for a model- based assessment of potential
water retention caused by land-use changes in a catchment in the Central Ore
Mountains (Saxony, Germany). The potential of flood control by land-use
management measures is highly dependant on the site-specific soil and relief
conditions and the rainfall event characteristics. The pre-event soil
moisture is distinctly lower under forest land-use. Furthermore,
infiltration, percolation in the subsoil is increased. These effects exist
for small/medium-scale events whereas they become marginal for extreme
events. |
