Abstract: This paper addresses high resolution inundation modelling in a transboundary context. In particular, flood wave propagation and inundation characteristics are simulated over a stretch of almost 100 km of river Meuse across the Belgian-Dutch border, using 2D fully dynamic modelling. This transboundary hydraulic simulation requires inflow hydrographs to be prescribed as upstream boundary conditions. However, existing procedures for generating flood wave hydrographs differ between the concerned regions. Therefore, we review the main characteristics of the existing regional procedures and compare the resulting synthetic hydrographs. Besides, transnational hydrological scenarios have been developed to investigate the impact of climate change on flood risk along river Meuse in both countries.
