Description
Ongoing technical work for municipalities of l’Horta Sud affected by the October 2024 DANA, focused on the territorial, hydraulic and urban analysis at catchment scale.
The event exposed the vulnerability of certain urban centres located where channels, infrastructure and runoff from several sub-basins meet. At some points, the concentration of flows caused water to partially enter urban areas; downstream, the accumulation of flow produced very severe impacts on the residential, productive and community fabric.
The strategy addresses the problem at a basin scale, combining territorial diagnosis, flood-attenuation criteria, improvement of hydraulic capacity, removal of critical points and the definition of spaces able to take on water in a controlled way.
The aim is not only to reduce the risk of future extreme events, but to transform the hydraulic corridor into a blue-green infrastructure: a system of protection, landscape, soft mobility and public space serving the territory.
