Abstract

Jeddah is the most important port city in the Kingdom of Saudi Arabia. The climate of Jeddah is mostly dry; however, events of intensive rainfall followed by urban flooding have been reported in recent history. These floods interrupt the logistics and lifelines of the city. In this study runoff analysis and Flash Flood management by the green roof low impact development (LID) control system, was performed using United States Environmental Protection Agency (EPA)’s Stormwater Management Model (SWMM). Six middle districts of Jeddah city had been selected and modeled in five sub-catchment areas. The local soil and geographic conditions were incorporated into the model. The effect of the soil-based, rooftop, LID system has been emphasized in the analysis. In flood simulations, 30–70% of the impervious area of each sub-catchment has been treated with LID. It has been observed that the LID application can significantly reduce the overall flood flow. Thus, simple but well-planned LID control systems can be effectively utilized for the flood management of heavily urbanized regions.

在沙特阿拉伯吉达山洪管理中应用基于土壤的低影响开发系统

吉达是沙特阿拉伯王国最重要的港口城市。吉达的气候大多比较干燥，但在最近的历史上，也曾发生过强降雨导致城市洪水泛滥的事件。这些洪水中断了城市的物流和生命线。本研究利用美国环保署（EPA）的雨水管理模型（SWMM），通过绿色屋顶低影响开发（LID）控制系统进行径流分析和山洪管理。研究选取了吉达市的六个中区，并在五个子流域内建立了模型。当地的土壤和地理条件被纳入模型中。分析中强调了基于土壤、屋顶的 LID 系统的效果。在洪水模拟中，每个子流域 30-70% 的不透水区域都采用了 LID 系统。结果表明，采用低能耗、低污染的系统可以大大减少总体洪水流量。因此，简单但规划合理的 LID 控制系统可以有效地用于严重城市化地区的洪水管理。
