Actividades humanas, qualidade e distribuição dos recursos hídricos: estudo de caso da Bacia hidrográfica do rio Revuè no distrito de Manica

Abstract

The present work is a practical application of the subjects taught throughout the course and addresses a topic of a hydrological nature related to society and the environment. Before relating human activities to the quality and distribution of water resources, reference is made to the physical-geographical characteristics of the area, in particular the climatic, geological and vegetation characteristics of the area, which are important for the quality and quantity of water. Throughout the work, there was an interest in identifying the human activities carried out in the study area and the possible impacts on the quality and distribution of water resources. In addition, from the results of water samples analyzed in the provincial laboratory for Hygiene, food and water in Manica and others resulting from bibliographical sources, an attempt was made to identify the concentration and possible origin of each of the substances present in the water. Finally, a classification of the water is carried out, based on the defined standards for possible uses. The methodology used was adopted, taking into account the objectives of the work, as the theme requires complementarity with other sciences. The conclusions drawn about the implications of human activities on water quality were based only on analyzed substances. However, due to material limitations on the part of the provincial laboratory for hygiene, water and food in Manica, the concentration of metallic residues, in particular mercury, which is used for the purification of gold during the washing process of this mineral, was not determined.
