MONITORAMENTO, POR MEIO DE GEOTECNOLOGIAS, DOS PROCESSOS DE INUNDAÇÃO E ALAGAMENTO NA BACIA HIDROGRÁFICA DO RIO DO BACURI, IMPERATRIZ-MA.

Abstract

Environmental problems have become increasingly frequent in large urban centers, greatly enhanced by human action. Currently, monitoring through geotechnology has become a very useful tool in combating and preventing the occurrence of environmental problems, since it becomes possible to identify, collect, process data or spatial scales of objects present on the Earth's surface. The aim of the work is to understand the areas affected by flooding processes, in the area of the Bacuri River Basin, located in the municipality of Imperatriz - MA, through the use of geotechnologies. To achieve this objective, the Copernicus Dem digital elevation model (DEM) was used, with a spatial resolution of 30 meters, projected in the software (Qgis 3.22), then the data was projected into the Hand Model where the area map was generated. susceptible to flooding. Subsequently, data from the Municipal Superintendence of Civil Protection and Defense (SUMPDEC) were used to map the main points affected by the flow of the Bacuri River. The results obtained found that the Bacuri river basin suffers greatly from flooding and flooding processes, generating disruptions on a social and economic scale for the inhabitants living in its vicinity. It is concluded that the work was extremely important to identify areas susceptible to flooding and flooding processes, since the municipality of Imperatriz suffers annually from such events.
