INTEGRATED URBAN DRAINAGE SYSTEM; THE CASE OF AYAT TO MEGENAGNA LIGHT RAIL TRANSIT SYSTEM ROUTE

Addis Ababa is one of the fastest growing cities in Africa and urbanization is known to increase the amount of runoff generated from the urban catchment. Due to urbanization and lack of proper design and management, the cities transport infrastructure has experienced frequent flooding. The application of Integrated Sustainable Urban Drainage System (SUDS) is a recent trend in developed countries (like the UK) for flood mitigation with added benefit of amenity and water quality. The aim of this study was to assess SUDS applicability in solving the existing drainage problem and minimizing the flood risk associated to transport infrastructure.
