| Abstract: | The reforested headwater watersheds in Japan are very important from the points of view of commercial and environmental aspects.
At the present time, much and varied research is running to assess and understand the hydrologic behavior of these watersheds.
The present study was conducted to evaluate the applicability of the deterministic model MUSLE in the Mie small steeply reforested
watershed. The model was tested and calibrated using accurate continuous suspended sediment data collected during eight storm
events in 2004. Results of the original model simulations for storm-wise sediment yield did not match the observed data, while
the revised version of the model could imitate the observed values well. The results of the study approved the efficient application
of the revised MUSLE in estimating storm-wise sediment yield in the study area with a high level of agreement of beyond 88%,
an acceptable estimation error of some 14% and non-significant difference in mean values. |
