One of the goals of this study was to identify an appropriate temporal
scale at which precipitation-related erosion in humid subtropical climates
can be effectively estimated. The temporal resolution of
precipitation parameters in this study ranged from weekly, to biweekly
, to multi-weeknscales. The weekly time scale did not produce significant correlation
between precipitation and erosion although the data captured
discrete precipitation events. Contradictory studies exist with regard
to the effect of discrete precipitation events on soil erosion. Either
very intense precipitation is associated with erosion, or the cumulative effect of long duration
low intensity events is more significant . Previous
studies in different soil and climatic regimes identified event-based to
weekly precipitation in the rainy season as primary drivers for soil erosion
.
