Water erosion is the geodynamic phenomenon that most affects the city of Brazzaville (Congo). A geological engineering mapping of the city was carried out with the objective of generating a map of water erosion hazard that facilitates the territorial ordering. The methodology focused on the processing and interpretation of Landsat and Radar SRTM images. From the geological engineering survey of the city it was made the types of water erosion Map for the diagnosis of the area. Thematic maps and the total hazard map were generated through a GIS. It is concluded that the districts located to the north, northeast and northwest of the city present the highest hazard level to water erosion, associated mainly with a low vegetation cover, sandy soil poor in clay and very erodible and the mountainous relief. |
