This research analyzes hydraulic geometry changes of the Peixe river occurred in a period of 106 years. The historical reference data are from the extinct Geographical and Geological Commission of the State of São Paulo. This 1906 expedition occour when the basin river system was still free of urban occupation and intensive farming. The explorers carried descriptions of the landscape surrounding the river (vegetation, topography, soil and the indigenous population) as well as cross sections on fluvial channel to check width, depth and discharge, which are remade by this research. Field data were obtained from five profiles, distributed between the middle and lower course, located in the municipalities of Tupa, Bastos, Parapuã, Mariápolis and Ribeirão dos Indios during the winter months, as done in 1906. The results accuse increase in width, depth flow velocity and flow and reduce the rates of slope and sinuosity. The geographical analysis of behavior river goes through the evolution of land use in time series and survey of rainfall and hydrological regime in the basin. It is known that in 1906 there was a natural dynamics in the watershed and after 1920 the vegetation is gradually withdrawn, increasing runoff and erosion development (AU) | |
