One of the issues that is still a problem in the upstream watershed, including the
water catchment area of Saguling Reservoir, is land use change. Changes in land
use in water catchment conservation areas into economic, industrial and residential
areas, will cause an increase in run-off during the rainy season and sediment
transport to the reservoir inlet, while changes in land use downstream of the
reservoir will cause an increase in demand. Therefore, research is needed to
determine the rate of increase in sediment yield that occurs in the watershed of the
Saguling Reservoir. The integration of USLE and GIS allows us to determine the
spatial distribution of parameters. Each factor in USLE is calculated using the
existing facilities in the GIS software. The results showed that there was an
increasing rate of sediment yield in the "Very Heavy" TBE category, while in the
"Medium" TBE category the trend of sediment yields showed a downward trend.
