COR E TURBIDEZ COMO INDICADORES DE PROCESSOS EROSIVOS NA BACIA HIDROGRÁFICA DO TAQUARAL SÃO MATEUS DO SUL – PR (2010-2011)

Abstract

The combination of natural and anthropogenic factors interfere in characteristics and properties of water, gives it a specific character in each place. The quality of water intended for human consumption has depended largely on the systems of land use on the slopes, erosion associated with the surrounding areas of production and water catchment, within a given watershed. Therefore, this study intends to show the configuration of land uses in the River Basin Taquaral in São Mateus do Sul - PR, between 2010-2011, and its contribution of sediment carried to the main river. As part of the methodology became the definition of four monitoring stations in rainfall and water features throughout the course of Taquaral River. These were defined according the sectorization of the main river and predominant land uses in each sector. Water samples were analyzed in the laboratory of SANEPAR - São Mateus do Sul. The parameters considered to relate to the presence of sediment were color and turbidity. The water samples were taken between August/2010 and July/2011, the 15th day of each month and every rainfall greater than 25 mm continuous event, an interval of 12 hours. The results indicated that there is greater sediment load transported to the Taquaral River along the upper course, where agricultural activities predominate in relation to the lower reaches where it is the urban occupation. It is hoped that this research can contribute to the planning of river basin management that is the basin catchment for urban and rural population of this municipality. Given this diagnostics, which referrals are made to inform and mobilize the population that occupies and uses this water catchment area, to preserve water quality and restore the areas most vulnerable.
