Integration between Torrent Protection Gray Infrastructures with Constructed Wetland to Achieve Resilience in Ras Gharib

Flooding and torrents are a seasonal phenomenon that hit a lot of cities every year around the world. As climate changes affect the world, cities are increasingly exposed to such threats especially those located on flood streams are most exposed to damages in the winter and the flooding season. In the past ten years, Egypt has been facing severe climate change effects like the increasing frequency of flooding in Egyptian cities. According to the Egyptian government, there are more than 1200 Egyptian cities and villages on flood streams and torrent tracks. These cities are distributed between the Mediterranean coast, Cairo region, Red Sea coast, Sinai and Upper Egypt, these and increasingly vulnerable towards the floods and their urban life is severely affected weather in old cities or in new planned cities. It is mostly located in the Eastern Desert at the east of the Nile. According to geologists and Meteorologists, these cities and their inhabitants are facing future hazards if they were not well prepared to handle floods.  The international experience in constructed wetland projects proved to be a successful technique maintaining floods and turning it into sources of development and increasing biodiversity. Several countries led by China have developed national strategies to use wetland parks as a defense tool against flood risks, at the same time these parks have become a source of income for their cities. This paper is a part of series of papers and researches for constructed wetland technology and opportunities to use it in Egypt. In this paper, the torrents and flood risks facing Ras Gharib city will be highlighted. Explaining the abilities of constructed wetland parks to minimize the damage and transform it into a source of strength, which will be a part of resilience city new policies. The research method is a comparative analysis between international project strategies and the Egyptian current strategies and actions to face flood and torrent risk. It will be the fundamentals of an Egyptian model that is compatible with the city's risks and challenges.
