In this region there are exposures of sandstones, siltstones, and argillites of the Adamantina Formation, belonging to the Bauru Group. Using satellite and radar images, superposition of drainage maps, toposheets geologic and pedologic maps and field trips, it was possible to discern (three geomorphological domains; a) hilly and interfluvial plateau in the divisories areas of Tiete - Aguapei and Tiete - Sao Jose dos Dourados mainrivers; b) colluvial surfaces located around the interfluvial plateau; and c) fluvial terraces and floodplains. The indiscriminant use of the soils is accelerating the erosive process, increasing the sedimentation of the river beds, the size of the floodplains and prejudicing the water quality, used to supply the rural and urban population. -from English summary
