Abstract: As recalled by Genouel, Comby, Le Lay, and Biron (2024), urban flood waters can carry a wide range of matter, from urban furniture to dissolved substances. The present work focuses on the transport of dissolved substances in urban flood waters (e.g. chemical and bacteriological matters). The main objective is to experimentally investigate the intrusion of a pollutant into a porous city block, which is surrounded by a flooded street network (note that the non-porous block configuration was studied by Fagour, Proust, and Mignot (2024)). In particular, we attempt to answer the following question: how does the number of passages in the city block facades affect the temporal and spatial variability of pollutant concentrations within the block?
