Method for Water Depth Mapping over crops during floods based on Copernicus and DTM open data

A simplified morphological analysis was performed on Sentinel data and Digital Terrain Model (DTM) by DTM tessellation to map water depth. Submerged areas were classified by proximity analysis to be able to distinguish between areas with soil already saturated versus areas where water was coming from the river. Sentinel-2 pre-flood images were used to map crops that were still to be harvested at the time of the flood.
