Urban Geomorphological Processes in Pécs, Southwest-Hungary, Triggered by Extreme Weather in May and June 2010

In urban areas with increased surface runoff, high-intensity rainfalls may inflict serious damages to various structures. Authors analyze extreme precipitation events with the purpose of compiling an urban geomorphological hazard map for Pecs, drawing on the experience gathered from the May to June events in 2010. DEM and digitized cadastral maps were employed to survey the spatial distribution of the extraordinary events, their impacts on geomorphic processes and the resultant damages. The findings confirm that the incorporation of stormwater management into the urban hydrologic master plan could be highly beneficial for Pecs and many other municipalities. This way localized flooding could be avoided or reduced to manageable levels.
