Abstract
The upstream of Kamparwatershed represent the part of Siak Watershed in the Province of
Riau which has been degradated.This research aims to determine the location, wide, and
degree of the land criticality according to the erosion hazard level in the upstream of
Kampar watershed. So the research can determine the way, type, and priorities of
watershed management. This research used survey method and laboratory analysis of soil
samples. The survey was done by observing the land use and conservation applied to the
land unit. The data collected were rainfall, soil characteristics, slopes, crop management,
and land conservation techniques. The obtained data were analyzed using the USLE
formulation to define the erosion hazard level of the upstream Kampar watershed. The
results found that the erosion of the upstream Kampar watershedis in the high category.
The best practices to reduce the level of erosion hazard in the upstream Kampar watershed
are improving the crop management and land conservation techniques in an integrated
manner on each land unit.
