Size–frequency distribution of shallow landslides in the Black Forest, Germany

Landslides are a major hazard in mountainous regions, represent threat to human life, and cause substantial economic costs. While some landslide assessments, including hazards maps, available for Germany, their spatial coverage is not uniform. In the Black Forest, several landslides have recently attracted public attention, but this region has received limited consideration literature date. This study focuses on pattern size distribution of soil-borne submountainous valley Menzenschwand. A combination remote sensing, geophysical surveying, geotechnical testing was used map characterize inventory two selected hillslopes. statistical analyses, we observe larger proportion small-scale with below 100 m2 than usually reported similar studies. effect may be related low cohesion soil (glacial deposits). As result, cutoff at large sizes compared expected power-law tail found. maximum found about 1100 m2, largest should theoretically least 2500 95% probability. The probably due thickness, where 50% considered area depth bedrock 1 m or less. For location, result suggests that an increase frequency intensity rainstorms predominantly frequency, without increasing landslides. more general implication, contribution total overestimated if thickness considered, particular present-day projected future scenarios.
