TL;DR: Uncertainty of the upstream boundary can have significant impact on the model results, exceeding the importance of model parameter uncertainty in some areas, however, this depends on the hydraulic conditions in the reach e.g. internal boundary conditions and, for example, the amount of backwater within the modelled region.

TL;DR: This paper aims to further improve the exploitation of SAR images in hydraulic modelling and near real-time crisis management by means of developing image processing methodologies that allow for the extraction of water levels at any point of the floodplain.

TL;DR: An insight from the viewpoint of a crisis information operator is given on the geo-information service provided within the International Charter "Space and Major Disasters", and the rapid mapping service's future is discussed in the light of international programs and coordination.

TL;DR: In this paper, an attempt was made to sequentially assimilate into a simple lumped conceptual rainfall-runoff model an estimate of the soil saturation level from field measurements of water table depth and backscattering of the radar signal emitted by active microwave sensors on board ERS-1.

TL;DR: In this article, the authors applied principal components analysis (PCA) to a time series of European Remote Sensing (ERS) synthetic aperture radar (SAR) scenes of the Alzette River floodplain (Grand-Duchy of Luxembourg) in order to examine the decrease of the radar backscattering signal during drying-up phases following important flood events.
