These areas are especially threatened by heavy rainfalls. The latter are predicted
to increase due to climate change in future. The data were provided by a scope of
stakeholders. The analysis of such data layers led to maps that were provided by
an online and interactive map service developed during the project. The participants
always had the opportunity to look at the maps, to integrate datasets from different
sources, and to make comments so as to improve the maps. Furthermore, they were
enabled to produce new maps, using the numerous data layers. The maps, however,
were soon accepted as an ideal basis for discussion of problems considering varying
perspectives and scenarios. This way, the maps were appreciated as decision support
tools, on the one hand, and as a way to inform the public, on the other.
3.1.2 Defining Different Adaptation Options Based
on the Geographical Database
During workshops, the maps and different alternative measures to adapt to climate
change were discussed intensively. A prioritization of potential measures had to be
carried out, so as to find the most important and feasible measures that should be
realized in the pilot region within the next few months or years. The following list
mentions some of the options discussed:
• Reduction of soil erosion in agriculturally used areas.
• Change of the management of (small) rivers.
• Concept to deal with invasive neophytes.
• Adaptation of forest management.
• Improvement of disaster management (especially in conjunction with extreme
weather events).
• Change of administrative methods to include climate change adaptation in urban
planning.
• Adaptation of water provision and wastewater removal.
More and more, the focus of discussion was on problems in the field of riverbed
erosion and water management, coupled with the consideration of special interests
of farmers who cultivate land along the river. Buildings close to rivers, as well as
traffic (roads crossing rivers) close to the river can be endangered by erosion as well.
Therefore, two river catchments have been selected as exemplary within the “BebeR”project. The catchment area of the “Regenbeek” represents an area with partly high
riverbed erosion, which is caused by strong currents after snow melting periods
and/or heavy rainfall. Figure 2 presents the catchment area including a 3D-digitale
elevation model. Riverbed erosion can lead to the destruction of the riverbanks and
an unusual deepening of the riverbed. Mud flows can occur (as this already happened
some time ago, see Fig. 1), thus polluting villages. Furthermore, infrastructure (e.g.
roads, pipes) or buildings are threatened by the mud flows. Heavy rainfall can lead to
anomalous bank erosion. This is accompanied by extensive erosion of surrounding
arable land.
