With the increase of urbanization, conditions of the underlying surface and climate have been changed by human activities. This results in more frequent flooding and inundation problems in urban areas. Storm- inundation models based on hydrology and hydrodynamics require a large amount of input data (detailed terrain, sewer system and land use data). Simulation models are complex and difficult to build and run.
On the other side, upcoming availability of high resolution topography data (Lidar/DEM) together with advanced GIS/Geospatial spatial processing tools, permits to develop more efficient, accurate and simplified modelling approaches.
URBAN_SmartFLOOD is a simplified raster-based model for quickly mapping Pluvial/Flash-flood hazard and risk in urban area with a DEM-based depression-to-depression filling, spilling and merging process.
URBAN_SmartFLOOD algorithm computes and maps the areas of a terrain that are flooded in a given flash flood event by simulating how water flows on the terrain and fills up depressions.
The URBAN_SmartFLOOD Web Service is designed to provides end-users with the possibility to consistently and cost-effectively run in real-time flood hazard mapping related to specific pluvial scenarios and to support the design of resilience and adaptation plans in urban areas.
