Situated on a plain beneath the 800m escarpment of the Jabal al-Hejaz in Saudi Arabia, Jeddah was flooded after heavy rain on 25 November 2009. As the desert city extends across numerous wadis off the escarpment, it is prone to flooding after exceptional storms; however at twice the city’s yearly average, 90mm of rain fell in just four hours on that day. By noon, torrents struck many parts of the city, especially the poorer southern neighbourhoods where thousands of vehicles were caught in a traffic jam trying to escape. The death toll was 161, with damage to 8,000 homes and over 7,000 vehicles. The consequences of the floods drew criticism for wastewater management, flood mitigation and emergency response from the various responsible Saudi government organisations. This paper is to evaluate the measures taken after 2009 floods and disaster management and policies improvement since 2009, also this research paper presents a conceptual model to measure the Saudi Emergency System. The corresponding results are presented in process flow, causal loop and stock and flow diagrams which lead to further development using the quantitative phase of SD approach.
