Abstract

This work proposes a diffusive hydrodynamic modeling approach based on representing the city as an equivalent porous medium, in which buildings, walls, and other infrastructures are accounted for in the permeability tensor and the porosity of the medium. The developed model is numerically solved using the Finite Element Method, and the results are compared with those obtained through a detailed modeling of the street network. The findings show that the proposed approach combines computational efficiency and practical applicability for the study of urban flooding in large domains.
