abstract = "This article describes a procedure to define the path taken by a
liquid pollutant, since the location of its shedding to the end
point, given a drainage network. The TerraHidro system was used
for determination of drainage network by following these steps:
determination of the local flows between neighboring cells of
regular grid of altimetry, used as a model for relief; calculation
of accumulated area grid; choosing a particular drainage network,
which is a subset of the accumulated area grid, according to a
threshold value supplied by the user. Then, the user selects a
point about drainage simulating the location of pollutant liquid
spillage. With this information, the procedure that computes the
path taken by this pollutant is determined by TerraHidro. As the
area of contribution is important for determining the behavior of
water in a geographic region, two areas of contribution were
calculated, one for shedding point and other for the end point of
the liquid pollutant flow. This base can be incremented with other
relevant information to the study of the flow speed of the
pollutant, such as use and land cover, soil type, slope, flow of
the watercourses where the pollutant. The data used in this study
were surface models from SRTM 90 meters of horizontal resolution,
delineation of the State of S{\~a}o Paulo, and Petrobras oil
pipelines paths located in S{\~a}o Paulo State.",
