| Zusammenfassung |
| In this paper, we analyse the effectiveness of flood management measures
based on the concept known as "retaining water in the landscape". The
investigated measures include afforestation, micro-ponds and
small-reservoirs. A comparative and model-based methodological approach has
been developed and applied for three meso-scale catchments located in
different European hydro-climatological regions: Poyo (184 km2) in the
Spanish Mediterranean, Upper Iller (954 km2) in the German Alps and
Kamp (621 km2) in Northeast-Austria representing the Continental hydro-climate.
This comparative analysis has found general similarities in spite of the
particular differences among studied areas. In general terms, the flood
reduction through the concept of "retaining water in the landscape"
depends on the following factors: the storage capacity increase in the
catchment resulting from such measures, the characteristics of the rainfall
event, the antecedent soil moisture condition and the spatial distribution
of such flood management measures in the catchment. In general, our study
has shown that, this concept is effective for small and medium events, but
almost negligible for the largest and less frequent floods: this holds true
for all different hydro-climatic regions, and with different land-use, soils
and morphological settings. |
