RAMOS, Maryuri; BERROTERAN, Dyanna  e  NAJUL, María Virginia. Patterns of occupation of the territory in the middle basin of the tuy river and its impact on the quality of the water. Rev. Fac. Ing. UCV [online]. 2014, vol.29, n.3, pp.17-28. ISSN 0798-4065.

Since 1956, the Tuy River is one of the sources of water supply for the capital region and shows recurring problems of quality, previously reported by several authors. In order to provide information to support decision-making for the integral management of the basin, this work describes the relationship between the patterns of occupation of the territory and the variation in the quality of the water in the middle basin of the Tuy River (CMRT). Several CMRT characterization studies during the period 1968-2008 were analyzed. Trends in the quality of the water were compared with the reported patterns of territorial occupation, qualitatively identified by aerial and satellite imagery of each zone, taking into account the territorial footprints documented. We identified and characterized the following types of territorial occupation: planned and unplanned urbanization, industrial areas, agricultural areas and reservoirs. It was found that the trends in levels of pollution for the river coincide with variations in the type of occupation and use of the soils. The source of the contamination is anthropic and reaches the river because of flaws in the management of the basin. It is recommended to implement effective measures to reduce the impact that will occur in the body of water, if the urbanizing area continues as until now.
