(Erosion Prediction in Ungauged Basins: Integrating Methods and Techniques (Proceedings of Symposium HS01 held during IUGG2003 at Sapporo, July 2003), IAHS Publication No. 279, 2003, pp. 109–116).
Runoff and erosion data were collected in an experimental basin during natural rainfall events on plots and microscale basins. A hydrodynamic model was chosen for calibration and simulation, and calibration was carried out for each of the chosen observed events. Two model parameters were related to an antecedent moisture index. The accuracy of the calibrated model and the parameters was tested by applying them to an adjacent microscale basin. The model simulated the runoff values well, even with the estimated parameter values, but the calculated erosion values showed larger variations, underlining the complexity of the erosion process. However, the model could be considered a reasonable tool for obtaining a first estimate of erosion from basins without adequate data but with similar characteristics.
