Abstract: The water cycle can be affected by violent events such as earthquakes, tsunamis, floods, … In France, 17 millions of inhabitants are exposed to flood risk. One challenge during floods is to be able to access to people refugee over buildings. In order to investigate the hydraulic context generated by the grouped obstacles representative of a submerged housing estate, a preliminary experimental study was conducted. We experimentally study the flow in the presence of rows of macro-roughnesses representative of a submerged housing estate, and this for situations representing both current and more intense floods. After presenting the experimental configurations, the experimental results are given and discussed. The first conclusions are completed by the perspectives.
