Diagnóstico da disponibilidade hídrica na bacia hidrográfica do Rio Manso - MG

Abstract

The water is an essential natural resource to human development and its activities. Nevertheless, its availability has been widely discussed in several countries in the world, especially in Brazil. This resource shortage, associated with the watercourses degradation and the increased demand for multiple usage, has led to conflict scenarios over the water usage where its availability is lower than the demand. Objective devaluate and spatialize the water availability at the Rio Manso’s watershed in MG. The implementation of the methodology included four main steps: (I) data collection; (II) water usage bestowal data processing; (III) databases export into GIS environment; (IV) water demand calculation and water availability spatialization. 215 points of water capture, with valid bestow processes were identified, in the watershed. These represent a demand of 0,1831 m3/s associated to 15 different usages, which the main ones are: irrigation, human consumption, animal watering, aquaculture, mining and vehicle washing. Although the major part of the watercourse is founded in a state of water availability, some points presented were in a state of attention, pointing out an integrated watershed analysis need, in order to guarantee its sustainability.
