Manifestações patológicas em edificações em áreas de risco de inundação e alagamento do Rio Camarajipe em Salvador-BA

Abstract

Within the historical context of Brazil, urban rivers could be of great importance for the water supply, source of income and leisure for the community. However, the current scenario is very far from that due to the pollution and degradation of these rivers. This situation also occurs in the city of Salvador, affected by pollution, urbanization and disorderly land occupation, such as the Camarajipe River basin, one of the three largest urban rivers in the city, which served as Salvador's main source of water supply. The river is in very poor condition due to the impermeability of the urban soil, pollution with solid waste and lack of adequate sanitation and drainage, contributing to the occurrence of flooding and waterlogging events that put the surrounding buildings at risk, with economic, social and public health damage. The objective of the study was to verify how flooding and waterlogging events can favor buildings presenting pathological manifestations. To this end, the study mapped points near the Camarajipe River, identifying buildings that exhibit pathological manifestations on their facades and how these occurrences may have been caused by flooding. An analysis of articles and bibliographic sources, data analysis and environmental reports were carried out. The research was descriptive and exploratory in nature, with field records of stretches of the Camarajipe River, mapping 20 points along the course of the river and highlighting the main pathological manifestations found in buildings in areas at risk of flooding. The results obtained demonstrate that at least one of the 5 types of pathological manifestations studied can be observed in all points collected, concluding that they are frequent in buildings in these areas at risk of flooding and inundation of the Camarajipe River. This situation is apparently aggravated by the high population demand, associated with the dangerous and disorderly occupation of the land.
