The project has as objective to adjust the model QUAL2K to “Ribeirão Claro” river to evaluate the behavior of OD and DBO when are simulated the following sceneries: (i) implantation of a hypothetic wastewater station treatment that treats all the effluent thrown nowadays in the body of water; (ii) increase of withdrawal flow of DAAE to public supply and (iii) increase of nowadays flow of wastewater throwing, being the two last caused for the population increasing. The results obtained allowed to conclude that the model QUAL2K presented a good adjustment to the variable OD and a reasonable adjustment to the variable DBO, being that the same was suitable to the simulation of the sceneries proposed.

The evaluation of soil permeability throughout the weathering profile is one of the most important features to be considered in environmental studies. This study, developed from field testing and analysis of data obtained by geostatistical methods, aims at mapping the permeability around the Ribeirão Claro river. The intent is to simulate an accident with toxic liquids where soil permeability is of fundamental importance. Another purpose of the research was to determine the minimum time that, in the event of an accident, a possible contaminant to reach the water table level and be routed to the nearest drain, in this case, the Ribeirao V Claro river constitutes fundamental information. The studied area of approximately 4 km² is located within the UNESP-Rio Claro campus, consisting of colluvial soil from Fm. Rio Claro superimposed on residual soil of Fm. Corumbataí. The method used to determine the permeability is the concentric cylinders performed on a sampling grid with 64 points containing spacing of 5 meters EW and 10 meters NS. In the places of permeability tests were collected samples for laboratory determination of the percentage of fines. From particle size analysis was performed and analysis statistical and geostatistical on this data. The histogram was based on the statistical studies, and the semivariograms were based on geostatistical estimation methods. Based on the comparison between the maps and the data obtained, it was determined that the percentage of fines in colluvial surface soil has little influence on permeability, which the proximity to the Ribeirao Claro river, the eastern portion, a factor that influences the distribution of permeability values
