Resumo
O manejo de bacias hidrográficas é uma forma de analisar e monitorar o ambiente como um sistema de causa e consequências na exploração dos recursos naturais. Esta pesquisa teve por objetivo diagnosticar o recurso hídrico do rio Uberaba, como subsídio para a gestão das áreas de conflito ambiental. Com extensão de 2.419,04 km2 e perímetro de 308,04 km, abrange os municípios de Uberaba, Veríssimo, Conceição das Alagoas, Planura e uma pequena porção de Campo Florido. Considerando as características do rio Uberaba e o uso e ocupação do solo, dividiu-se em 5 (cinco) áreas distintas, no qual foram coletadas amostras de água. A partir da aplicação diagnóstica das variáveis físicas conservacionistas identificaram-se as áreas de conflito no rio e em seu entorno. Dentre as análises dos parâmetros hidrológicos da água, os que apresentaram resultado significativo quanto aos conflitos de uso do solo foram: o potencial hidrogeniônico (pH), oxigênio dissolvido (OD), potencial de oxirredução (ORP), condutividade elétrica, temperatura, alcalinidade e turbidez. O principal uso do solo na microbacia foi observado à ocupação com pastagem, seguido de florestamento e agricultura intensiva com as seguintes culturas: milho, soja e cana de açúcar
The watershed management is a way to analyze and monitor the environment as a system of causes and consequences of the exploitation of natural resources. This study aimed to diagnose the Uberaba River water resource, as a subsidy for management of areas of environmental conflict. The extension is about 2419.04 km2 and a perimeter of 308.04 km, covering the municipalities of Uberaba, Verissimo, Conceição das Alagoas, Planura and a small portion of Campo Florido. Considering the characteristics of the Uberaba river and the land use and occupation, the river has been divided into five (5) distinct areas in which water samples were collected. From the diagnostic application of the physical variables conservationists, it have been identified the areas of conflict in the river and its surroundings. Among the analyzes of the hydrological parameters of the water, which had significant results regard to conflicts of land use were the hydrogen potential (pH), dissolved oxygen (DO), potential redox (ORP), electrical conductivity, temperature, alkalinity and turbidity. The main land use in the watershed was observed to occupy pasture, followed by forestry and intensive agriculture with the following crops: corn, soybeans and sugar cane
