Social pressure on alluvial plains and deltas is large, both from an economic point of view and from a nature conservation point of view. Gradually, flood risks increase with economic development, because the expected damage increases, and with higher dikes, because the flooding depth increases. Global change, changing social desires, but also changing views, require a revision of flood-risk ma...

[1] Ensemble streamflow forecasts obtained by using hydrological models with ensemble weather products are becoming more frequent in operational flow forecasting. The uncertainty of the ensemble forecast needs to be assessed for these products to become useful in forecasting operations. A comprehensive framework for Bayesian revision has been recently developed and applied to operational flood ...

The last two winters in central Europe were unusually cold in comparison to the years before. Meteorological data, mainly from the last 50 years, and modelling studies have suggested that both solar activity and El Niño strength may influence such central European winter coldness. To investigate the mechanisms behind this in a statistically robust way and to test which of the two factors was mo...

Almost two centuries of human interventions at the Upper Rhine to adapt the river systems to led to a serious increase of the flood risk and potential damage downstream. In 1982, the two riparian countries, Germany and France, agreed to re-establish the former protection level against a once-in-200-years flood, with Germany taking most of the workload. This can be considered as the starting poi...

Abstract. Monitoring environmental phenomena with assistance of remotely captured data is increasingly important in studies. The observation midge infestation or bark beetles can be considered a non-direct approach to their environments some cases impact on the ecosystem. Multispectral hyper spectral by aircrafts UAVs assist such areas. We want describe technology sensors, way process data, ext...
