Use of Geotechnology in Flood Mapping on Land Use Scenarios: Case Study Bairro Alto Sumaré - Mossoró / RN
Urbanization; Remote Sensing, GNSS, GIS, Northeast Brazil, Climate Changes
Floods have become more common events every year in urban spaces around the world. This problem has been studied both as consequence of climate change and the alteration of urban space. Under this second approach will be studied the floods problems in the Alto Sumaré neighborhood in the municipality of Mossoró/RN. This municipality has been growing in the process of significant urbanization in the last 10 years, leveraged by the Federal Government's Minha Casa Minha Vida Program (PMCMV). Even though it is a program where there is an orderly urbanization and with the implantation of the drainage infrastructure, the neighborhood has been suffering floods. Thus, this research proposes as a goal a new methodology to analyze the susceptibility of newly installed urban elements to the rapid events of floods, taking as a study area the Alto Sumaré neighborhood in Mossoró / RN. The approach will be made using geotechnologies such as Global Navigation Satellite System (GNSS) and High Precision Remote Sensing (use of Google Earth images), integrated with other parameters such as drainage system, processed in a Geographic Information System (GIS), in order to evaluate the events already occurred and to simulate future situations based on the urbanization of the neighborhood in the last decade.
