Flood Inundation Mapping
Overview
Flood inundation mapping identifies where water spreads and, in some systems, estimates its depth or predicts how flooding will change. Methods combine satellite observations—especially Sentinel-1 radar, which can see through clouds, and optical imagery—with elevation data, using segmentation networks such as U-Net and transformer or foundation models. Multisensor fusion, generative image reconstruction, and physics-guided models help fill observation gaps and produce maps that are more consistent with terrain and water flow. A key challenge is reliable transfer to new flood events and landscapes: vegetation, buildings, clouds, sensor misalignment, and inconsistent reference maps can all undermine accuracy, while aggregate pixel scores may not reflect street-level usefulness or physical plausibility.
