2. MATERIALS AND METHODS
This study used rainfall, runoff, and SY data to establish a relational
curve between the potential maximum retention (S) and SY. Land use and
soil data were incorporated with the S–SY curve to estimate the spatial
distribution of the potential maximum erosion. Finally, a digital
elevation model (DEM) was used to determine the subdivision delineation,
and the top-priority management area (Figure 1) was selected based on
the potential maximum erosion and slope of each unit area.
