This map was derived by applying the
sediment yield
curve to a map of mean annual precipitation

(Follow links for Maps and Digital Products, then to Sample Images).
It does not account for
other important factors such as slopes, soil characteristics, and the
distribution of rainfall among numerous small events or fewer large
events.
