Hydro-sedimentologic models are useful in the environmental analysis of unmonitored watersheds. However, the models must be calibrated and validated for accurate predictions. The objective of this study was to calibrate MUSLE for the conditions of the Piripipau river basin (Brazil), using hydrologic and sedimentologic data from 1999 to 2005, and to validate the calibrated model with another data set (1998, 2006-2009). MUSLE’s a coefficient was calibrated fitting observed and calculated sediment yield values of individual events, using observed hydrologic data […]

The objective of this study was to evaluate the effect of the rainfall variability on the runoff and sediment amount in the Pipiripau river basin (A = 235 km2), in the Distrito Federal, Brazil. To represent the climatic variability of the historic precipitation series, 5 years were selected: the moistest, the driest, an average, and 2 years representing the standard deviations from the series (half-wet and half-dry). After the calibration of the model with basin rainfall and runoff data, each rainfall event was simulated […]
