Abstract

This work presents the Mapping of Geological Risks on the slopes of the Todos os Santos River, in Teófilo Otoni / MG, with the objective of knowing, identifying, analyzing and mapping the risks on the slopes, in the stretch of the Aécio Cunha dam to the road station in downtown. The relevance of this work was based on the need to present, report on environmental impacts and warn of risks. A bibliographic and field research was carried out, with a case study in the area using data collection techniques. In the field research, a mapping of risk areas was carried out in the years 2016 and 2021. Fourteen sectors were identified in the coverage area, among them 08 sectors presented risk areas, six sectors with risks related to mass movement, where the sectors 01 and 02 presented low risk (R1), sector 07, 13 and 14 medium risk (R2) and sector 09 and with high risk (R3). Sectors 03 and 12 were classified as areas of risk of inundations and spate with low risk (R1) and high risk (R3) respectively, and within the sectors of the coverage area, none presented very high risk (R4). From the mapping of risk areas and their association with mass movement, inundations and spates, it is possible to adopt measures to minimize risks, implement actions, stimulate the effective participation of society and make data available to government institutions, as well as present measures to be instituted, with the objective of bringing benefits to the whole society.
