The use and land cover analysis is one of the fundamental steps for performing the strategic planning of a watershed conservation. This study aims to analyze the landscape of Ribeirão João Leite Watershed located in the state of Goiás northwest of the Goiânia city, using geoprocessing tools as Geographic Information System (GIS) and Remote Sensing in order to provide input to generate an environmental diagnosis of the same. This study also permitted an evaluation of different scenarios in estimating sediment production in the reservoir supply and Ribeirão João Leite watershed using the hydrosedimentological SWAT model, which showed that among the proposed scenarios the backdrop of native vegetation as land use and cover the predominant soil showed a lower value in the estimation of sediment production in the watershed, while the current watershed use presented the highest value.
