A System for Analysis and Simulating Hydraulic and Hydrogeological Risks Through WebGIS 3D Digital Platforms

The research activity carried out has demonstrated how simulation tools developed through WebGIS3d digital platforms are capable of producing approximate forecasts on the effects of potentially catastrophic meteorological phenomena that may affect riverbeds in the territories observed. This work presents an analysis and simulation platform with graphic representation of the results in the form of three-dimensional animation. This methodology may represent a useful tool for all those bodies and organizations that need to create hypothetical scenarios for the management of emergencies related to flooding events of watercourses, especially in the areas of maximum hydrogeological vulnerability in the Italian territory. These scenarios are particularly useful in cases where watercourses are located near inhabited centers, industrial areas or strategic infrastructures, where the risk of material damage and danger to the population is greater. The simulation is based on the morphology of the land adjacent to the bed of the affected watercourse, taking elevation into account to determine the direction of expansion of the water mass. Such scenarios are particularly useful in cases where watercourses are located near built-up areas, industrial areas or strategic infrastructures, where the risk of material damage and danger to the population is greater. The simulation is based on the morphology of the terrain adjacent to the affected watercourse bed, taking elevation into consideration to determine the direction of ex-pansion of the water mass. A distinctive aspect of the platform is its extreme speed in the resolution of simulations, which also allows the tool to be used in real time. This means that during the occurrence of a meteoro-logical event, the platform can be used to monitor the evolution of the situation and predict the effects of any persistence of the phenomenon over time. This real-time forecasting capability is crucial for making quick and informed decisions, thus reducing reaction times and improving emergency management on the ground, with a potential positive impact on the safety of the population and the protection of infrastructure.
