dc.description.abstractThe impacts caused by accidents involving oil spills in freshwater affect the environment but also cause socioeconomic harm to local people. In order to help identifying physical environments sensitive to the presence of a hydrocarbon, this study was carried out by applying a fluvial sensitive environmental index to oil (ISF), adapted from the coastal environment. To achieve this goal, a Tiete river stretch was selected, where field surveys were carried out covering by boat 146.9 km of the river. Marginal geomorphological characteristics were observed, and the beginning and the end of each segment were identified with GPS and recorded with photographs. The organization of a GIS database and the classification of the ISF enabled to identify that the index 10, characterized by alluvial deposits, is present in 51.1 km of the banks, which is equivalent to 34.8[%] of the total area, the most recurrent index in the study area. However, considering the ISF 9 and 10, the most sensitive ones, a total of 40.5[%] of the river margins is considered with high environmental sensitivity to oil, and these settings are related to the dam of Tietê river for the construction of Barra Bonita reservoir.en
