Abstract
- 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 hydroclimate. 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 landuse, soils and morphological settings.<br />Most of this research was done within the ERANET-Crue project "Room for the River", which was sponsored by: Lebensministerium (Austria), Bundesministerium fur Bildung und Forschung (Germany) and Ministerio de Ciencia y Educacion (Spain). We would like to thank each basin authority and national weather agencies for providing the hydro-meteorological data. The authors would like to thank to the Editor Andreas Gunther and two anonymous referees for their valuable comments.
