Abstract

Nice Metropolis in Alpes Maritimes, France is prone to flood. The city is crossed by the Lower Paillons River (LPR). Its discharge for a return period of 100 years is estimated at 794 m3/s. Part of the river is covered by 2 km. In addition, there are two retention storages in the river bed and a floodable road tunnel on the left bank. Due to the increase in urban development, flood management is challenging. An existing decision support system (DSS), Aquavar, uses DHI Mike tools to reproduce runoff for the Lower Var River in the same region. To extend this system to the LPR and reinforce flood management, a new modelling tool adapted to the characteristics of the LPR is needed. Consequently, this research utilizes the DHI MIKEPLUS tool to develop a 1D–2D coupled model for real-time flood management. The results demonstrate that flood events like those in 2017 and 2019 were correctly reproduced. The linear regression R2 is above 0.8 for all stations. It was also estimated that the covered river (CR) should stay clean to avoid widespread flooding in the urban area. Overall, the model is useful for simulating flow in real time and can help sustain urban development.

法国尼斯覆盖的下帕伦斯河实时决策支持系统的洪水建模

法国滨海阿尔卑斯地区的尼斯大都会容易发生洪水。下帕伦斯河(LPR)穿过这座城市。其100年回复期的流量估计为794立方米/秒。这条河的一部分长2公里。此外，河床上还有两个蓄水池，左岸有一个可淹水的公路隧道。由于城市发展的增加，洪水管理具有挑战性。现有的决策支持系统(DSS) Aquavar使用DHI Mike工具来重现同一地区下瓦尔河的径流。为了将该系统扩展到LPR并加强洪水管理，需要一种适应LPR特点的新的建模工具。因此，本研究利用DHI MIKEPLUS工具开发了用于实时洪水管理的1D-2D耦合模型。结果表明，2017年和2019年的洪水事件得到了正确的再现。所有台站的线性回归R2都在0.8以上。据估计，被覆盖的河流(CR)应该保持清洁，以避免城市地区的大范围洪水。总的来说，该模型对实时模拟流量很有用，可以帮助维持城市发展。
