Abstract:
Soil loss plots on open and under canopy sites were installed to study the effect of the canopy on interrill erosion. The erosion rate under the canopy was smaller than that on an open site, and it was highly correlated with the maximum rainfall intensity for 3 hour and total rainfall, independent of the slope angle. The throughfall rate showed a relatively continuous value under high rainfall intensity conditions, although varied with rainfall intensity. When the throughfall rate was initiated at a relatively continuous value, the rainfall intensity was very similar to the threshold of rainfall intensity for erosion under a canopy. These results imply that the canopy storage had been changed due to the rainfall intensity, and this change affected the interrill erosion under the canopy. These results will contribute to the development of an erosion prediction model under a forest canopy.
