| Abstract | This paper analyses the hydrological effects of climate change on flood risk along river Meuse with a focus on economic damage on the Belgian part of the basin (Wallonia). Nevertheless, the approach is developed in the scope of a transnational effort to achieve consistent flood risk management throughout the international basin of river Meuse.
We first review hydrological scenarios which have been developed at the scale of the Meuse basin. Next, we describe how hydraulic modeling has been conducted to produce the necessary flood maps for the subsequent exposure and vulnerability analyses.
The risk modeling employing a monetary approach, was performed at a meso-scale using European land use maps (CORINE) and regional geographic database (PLI), aggregated into a set of five damage categories.
For each damage category, appropriate damage functions and specific values have been used.
In this paper, the focus is set on comparing several approaches to calculate the specific price of the residential land-use category in Wallonia. Through a sensitivity analysis, we show the influence on flood risk of using these different approaches as well as several damage functions and climate change scenarios. |
