Infraestrutura de drenagem sustentável em assentamentos informais. caso de estudo: bacia de Maxaquene

Abstract

Floods are repeatedly reported in urban centers in Mozambique, and most of the time, they are justified as natural disasters caused exclusively by high rainfall during a certain period of the year. However, the explanation for such occurrences is due to a set of natural (meteorological) and anthropogenic factors. Given this, it is essential to promote alternative and sustainable techniques to requalify urban drainage infrastructures. To achieve this purpose, the various techniques of Sustainable Urban Drainage Systems (SUDS) were researched, their advantages and disadvantages, materials to use in each system and their efficiency. Based on the various SUDS, a sustainable urban drainage system is proposed in accordance with the local reality. The analysis of the information contained in the present work shows that SUDS are a viable alternative in terms of efficiency and drainage control in urban areas, as is the case in the neighborhood of Maxaquene C, in the city of Maputo, the place selected to test the technology .
