Abstract
-
This work addresses the hydrological behavior in the basins of the Aguapeí and Peixe rivers, which drain part of the region of the Western Plateau of São Paulo state, Brazil. The spatial variation of the water production per unit area in the hydrographic basins was evaluated, taking as a reference different hydrological periods of the historical series of data. To this end, the hydrological regime of the rivers and the drainage area associated to the sampling stations were considered. The obtention of the fluviometric regime and hydrological periods were based on daily, monthly and annual data of historical series. The average specific flow rate was determined by the ratio between the average flow rate in a given measurement section and the respective drainage area. The results reveal changes in the spatial patterns of Qe. The stations located in the upper basin of the basins had a greater data variability in the three hydrological periods, which was expected. The increase in specific water production in certain hydrological periods can intensify the laminar and linear erosion processes, which may be an additional problem for areas with inadequate land management.Keywords: Hydrological Variability; Hydrological zoning; Specific flow; Peixe River.
