| Resumo: | [EN] Hydraulic modeling during floods is essential for the development of hazard and risk maps associated with flooding. This involves a physically based two-dimensional mathematical modeling approach that solves the Saint-Vênant system of equations. Based on simulations carried out for the mid-to-lower basin of the ravine systems Poyo-Torrent and Poçalet-Saleta within the l¿Horta Sud district, the analysis focuses on the flood event (its dynamics, maximum extent, etc.) and the overflow following the cut-off low (DANA) rainfall (Mediterranean high-impact weather event) in October 29, 2024. The reliability of the model is demonstrated through its consistency with the area¿s complex geomorphology and observed water level data, among other factors. The flood analysis enables an understanding of its dynamic behavior, the maximum extent reached by the free surface across the territory, water depths at various points of interest, flow velocities, discharge rates, and more. It also highlights the impact of major transportation infrastructures on the flooding process. Furthermore, the analysis of overflow flows helps explain the material damage caused and, most importantly in our case, provides a tool for locating missing persons after such extraordinary events. This is achieved by evaluating the hydraulic power of these flows¿understood as an indicator of their transport capacity. By tracing the paths of these high-power overflow flows, it is possible to identify zones where energy dissipates, which are potential locations for missing persons. The tool developed proved useful for emergency services during the October 29 event. |
