Influence of different land management measures on runoff formation and concentration in agricultural area catchments (EBALE)

Funded by the German Research Community (DFG)
Period: 2006 - 2011
Project manager: Univ.-Prof. Dr.-Ing. Markus Disse

In the framework of the research project the runoff formation and concentration considering different land management measures in small, intensely sampled catchments (lower mesoscale up to a maximum of 6,3km2) is analysed and physically modeled. Datasets from conventionally , integrated (optimised conventionally) and ecologically cultivated catchments are used. There is a focus on quantifying of hydrological interdependency between the processes, which are induced by different land uses and cultivation measures, and the effect of local measures for reducing runoffs.
The modeled processes can be verified, calibrated and validated separatly as well as in their interactions because the data has high spatial and temporal resolution and processes are gauged individually (e.g. silting of soil). After identification of runoff regulating mechanism, scenarios are calculated, which give a quantifiable conclusion about the effectivity of water retentioning cultivation forms and canopies. 

Thereby possibilities and limits of decentralised flood protection are demonstrated. Concluding testing calculations are made for the validated modell with a bigger screen width, to get first perceptions for a possible regionalisation.
