Morphometric Characterization of the Lova River Sub-basin in the Perimeter of the Concession of the Catoca Mining Society with Geotechnology for the Definition of Environmental Indicators

The present study of "Morphometric Characterization of the Lova River Sub-basin in the Perimeter of the Concession of the Sociedade Mineira de Catoca with Geotechnology for the Definition of Environmental Indicators", aims to determine the morphometric aspects of the Lova River sub-basin, located in the perimeter of the concession of Sociedade Mineira de Catoca, Lda. From the digital modeling of conditioned hydrological elevation, using the ArcMap/ArcGIS 10.8 software, data were generated that enable the delimitation of the basin and the analysis of critical variables. These morphometric parameters, such as drainage density and slope, serve as essential tools for the definition of environmental indicators and the sustainable planning of mining operations and environmental recovery. The approach integrates remote sensing techniques and geographic information systems, providing a comprehensive view of the hydrological and environmental conditions of the area. The results highlight that the sub-basin has distinct morphometric characteristics, such as a total area of 162 km2 and predominantly smooth relief, with significant implications for runoff and erosion dynamics. Parameters such as concentration time and drainage density reveal a moderate hydrological response, being useful to guide local environmental management. The analysis highlights the importance of using geotechnologies in the management of natural resources, contributing to the development of strategies adapted to the particularities of the sub-basin, with the potential to promote sustainable practices and minimize environmental risks.
