Effects of Urban Occupation in Rivers Morphology: The Case Study of Upper Pedras River, in Jacarepaguá District, at the Tijuca Massif

Abstract

This paper discusses the effects of urban occupation on rivers morphology and how they contribute to increase landslide risks from extreme precipitation events. It presents results of the research “Applying Innovative Urban Infrastructure Technologies in River Revitalization Processes”, which aims to expand the understanding of urban river processes and non conventional urban infrastructure technologies, in order to propose on-site innovative sewage treatment and sediment control solutions for Rio de Janeiro urban favelas with local water supply. The methodology involves the formation of a collaborative network and the characterization of the urban settlement through field surveys and thematic mapping using ArcGIS 10.1. Water quality availability and improvement in urban watersheds demand a transdisciplinary approach, the articulation of complementary methods of analysis and collective planning, grounded on community involvement.
