 The flood flow in urbanized areas constitutes a hazard to both the population and infrastructure.Some recent catastrophes include the inundations of Nîmes (France) in 1998 and Vaison-la-Romaine (France) in 1992, the flooding of New Orleans (USA) in 2005, and the flooding in Rockhampton, Bundaberg, Brisbane during the 2010–2011 summer in Queensland (Australia).Flood flows in urban environments have been studied relatively recently despite many centuries of flood events.
