Assessing torrential endangered areas in Bavaria – consideration of log jams at culverts and bridges

According to the Bavarian Water Act there is an obligation for the water management authorities to determine torrential endangered areas. In a legal sense these areas are primarily potential flood areas however under consideration of typical torrential characteristics. Especially the involvement of solids in the process has to be regarded. Therefore a standardized modular approach to assess torrential hazards was developed at the Bavarian Environment Agency.
