SAR images of river inundation prove to be very relevant for operational flood management. However, common exploitation of satellite images of floods is generally restricted to a flood extent extraction. The usefulness of these images could be significantly improved by providing a hydraulic-coherent 3-dimensional (3D) characterization of floods and by integrating these Remote Sensing-Derived (R...

In recent years, flood susceptibility mapping has an important place among the studies carried out to take precautions against floods and mitigate damages possible negative effects caused by floods. this context, analysis, especially on a regional scale, been subject of research many researchers. study, methods used in were investigated. 155 published between 2014 2022 evaluated. general, deter...

Semi-automatic flood extraction procedures based on change detection techniques appear particularly adapted to plain flood monitoring and mapping. The change detector was specifically elaborated to analyse ENVISAT ASAR Wide Swath Mode data pairs, which appear very well adapted to flood monitoring over wide areas. The algorithm is based on two analysis levels: an enhanced ratio for strong change...

Remote sensing is recognized as a valuable tool for flood mapping due to its synoptic view and continuous coverage of the flooding event. This paper proposed a hybrid approach based on multiple endmember spectral analysis (MESMA) and Random Forest classifier to extract inundated areas in Yuyao City in China using medium resolution optical imagery. MESMA was adopted to tackle the mixing pixel pr...

In the past, mobile communication devices (such as cell phones) have not been utilized in flood forecasting and warning due to limitations in technology that have limited the ability of forecasters to gather and interpret geographical data in near real-time. This paper presents a prototype that integrates a GIS (geographic information system) with a hydrological model. It is a mobile mapping ap...

This paper explores a method to combine the time and space continuity of a large-scale inundation model with discontinuous satellite microwave observations, for high-resolution flood hazard mapping. The assumption behind this approach is that hydraulic variables computed from continuous spatially-distributed hydrodynamic modeling and observed as discrete satellite-derived flood extents are corr...

The knowledge of flood-induced ground effects and flood-water dynamics is a crucial issue for hydro-geomorphic hazards assessment mapping, thus river management land use planning. This paper the related 1:15,000 map illustrate lower Orba River (NW Italy) its adjacent floodplain geomorphic response to 21–22 October 2019 extreme flood. was estimated be 500-years flood caused severe damage cultiva...

Relationships between cataclysmic flood-generated landforms and flood hydraulics were investigated along Box Canyon, an 11 km long bedrock gorge of the lower Big Lost River. Geomorphic mapping along Box Canyon indicates that a cataclysmic flood completely inundated the gorge, resulting in large-scale erosional and depositional features on the adjacent basalt upland. Step-backwater hydraulic mod...
