[1] The proposed Surface Water and Ocean Topography (SWOT) mission would provide measurements of water surface elevation (WSE) for characterization of storage change and discharge. River channel bathymetry is a significant source of uncertainty in estimating discharge from WSE measurements, however. In this paper, we demonstrate an ensemble-based data assimilation (DA) methodology for estimatin...

Various regions in Europe have suffered from severe flooding over the last decennium. Earth observation techniques can contribute toward more accurate flood hazard modelling and they can be used to assess damage to residential properties, infrastructure and agricultural crops. For this study, detailed land cover maps were created by using IKONOS-2 high spatial resolution satellite imagery. The ...

Abstract. The local inertial two-dimensional (2D) flow model on LISFLOOD-FP, the so-called ACCeleration (ACC) uniform grid solver, has been widely used to support fast, computationally efficient fluvial/pluvial flood simulations. This paper describes new releases, LISFLOOD-FP 8.1, for parallelised simulations graphical processing units (GPUs) boost efficiency of existing ACC solver central (CPU...

In this paper we address the problem of parameter identification and parameter uncertainty estimation for the rainfall-runoff model LISFLOOD. This model forms the core of the European Flood Alert System (EFAS), an activity that forecasts floods at the European scale. LISFLOOD is driven by meteorological input data and simulates river discharge in large drainage basins as a function of spatial i...

Flooding events are becoming more frequent and the negative impacts that they causing globally very significant. Current predictions have confirmed conditions linked with future climate scenarios worsening; therefore, there is a strong need to improve flood risk modeling develop innovative approaches tackle this issue. However, numerical tools available nowadays (commercial freeware) essential ...
