Gray-to-Green Infrastructure for Stormwater Management: An Applicable Approach in Alexandria City, Egypt

Abstract

Stormwater management is employed to provide adequate planning, analysis, and design of storm drainage networks. This trend would minimize the human and socio-economic losses caused by stormwater while maintaining benefits from flash floods. Although stormwater in residential areas creates flooding and pollution, it is currently considered a viable resource of water supply. The management of stormwater aims at achieving sustainable environmental, ecological, and social aspects. However, the management of heavy rainfall and flash floods involves a substantial economic investment. Recently, green infrastructure has been used for stormwater management, considering construction techniques, materials accessibility, transportation routes, site planning and restrictions, payments, and profits. Hence, this chapter represents the implementation of the green infrastructure concept in stormwater drainage projects to minimize the negative impacts of heavy rainfall and flash floods on the environment. The findings of this work are highlighted regarding previous case studies reported in the literature. Moreover, this work gives a future vision for the application of green infrastructure in Alexandria, Egypt.
