A influência das captações de águas superficiais consideradas insignificantes na vazão do Ribeirão Água Fria, Palmas - TO

Abstract

economic development of any region. The management of the hidric resource is essential, it must be based on the management of water supply, for this is necessary understand the concept, the structure and how the hydrographic basin in order to ensure an enficient management of hidric resources. For the management of the hidric resources in Ribeirão Água Fria, in an enficient way, its necessary to know the hydrografic basin and its characteristics and define the demands for the ribeirão. The present work aimed to determine if the superficial cathment yet unknown to the environmental organ, they are committing the leak of Ribeirão Água Fria. The methodology for understanding the basin's behavior was based on the determination of morphometric indices, being them, the area and the perimeter of the basin, the coeficiente of compactness (Kc), the fator of shape (Kf), the rate of elongation (Re), the time of concentration (Tc), the drainage density (Dd), the hydrographic density (Dh), the roughness index (HD), the reason relief (Rr). The flow of the ribeirão were provided by Companhia de Saneamento de Palmas-Saneatins, between the years of 2001 to 2013, by means of these data it was determined Q90 reference flow into the basin. users of water resources in the basin have been identified through field survey and estimated population growth in 2005-2013 basin, with the help of satellite images. It was found that the flow of Ribeirao Agua Fria is not supporting the demand for funding authorized by the environmental agency, along with the funding without authorization, and such funding above the water availability of the river. In this scenario, it can be said that funding operations without authorization are compromising the flow of the water body, making it necessary that all funding operations in the basin are registered and inspected by the competent governing body, settling future disputes on water resources from the source study.
