dc.description.abstractThe soil productivity has been steadily declining constantly, due the action of erosion and inappropriate techniques use and soil management. In this scenario, the objective of the study was to determine the spatial dependence of sediment production located in the initial part of the watershed Pardo River - SP, during the years 1995 to 1999, in the sub-basins generated by SWAT 2009 model, using geostatistical tool. It was made a sampling by an irregular grid with 43 points located in the initial part of each sub-basin to represent the amount of sediment produced in each sub-basin and by geostatistical technique; it was found spatial dependence and was made contour maps using ordinary kriging. It was observed that the production of sediments showed spatial dependence, adjusting to the spherical model variogram and range near values. The year 1998 had the highest amount of sediment produced and in 1999 the smallest amount. For all years, the east part of the Rio Pardo basin was that presented the highest sediment concentrations.en
