Every possible structure was investigated by field investigation which resulted in a detailed database of 1002 landslides within the study area. The analysis of geological, lithological, topographical and morphological properties(spatial ratio, lithological and geological setting, length/width distribution, material properties and slope angle) revealed characteristic appearances of the landslides and possible relationships between different aspects. Strong relations between the lithological setting, spatial ratio of the mapped landslides and distribution of slope angle could be observed. This study shows the value of high-resolution shaded relief maps for detecting and mapping landslides in a large area with comparatively little work and time in comparison to the traditional approach to mapping. It reveals that many landslides were not known before. Landslides are much more common in Northern Bavaria and have a higher influence on the denudation rate of the Franconian Alb than expected before.展开更多

Yet the utilization of participatory processes can help to overcome this gap. In a practical example in the watershed of the Danube River and its contributing streams in Germany,we aimed to solve questions about the value of participatory modeling as a method to bridge the gap linked to flood polder planning and a relocation of a dike for protection against high floods(centennial floods and rarer). Local communities, citizen initiatives, and nongovernmental environmental organizations joined together for round table discussions initiated by the water management authorities. A participatory modeling process enabled these diverse stakeholders to engage with the experts who built the groundwater models for the planning process. As part of this study, two case studies are presented. In the first example, neutral mediators assisted the round table ‘‘Flood Polder Katzau(Danube)'' in order to cultivate mutual trust and understanding between the authorities and the former opponents of the project. This process is still ongoing,challenged by long-term planning and the more immediate obstacle of current political changes. The second case studyis located on the river Alz, a tributary of the river Inn,which flows into the Danube, where the relocation of a dike was planned. This article demonstrates how participatory modeling contributes to bridging the gap between a local resident's risk perception and real action in the case of flood preparedness.展开更多
