The experiences and problems in the establishment of the USLE factor were encountered and
learned. The creation of the factor layer should be conducted in the basis of subwatershed.
Difficulty in the establishment of the LS factor layer could be solved using suitable software
package. The values assigned to the USLE factor depend greatly on the empirical study. The
dynamic of soil erosion phenomena may result in accuracy assessment ever though the integration
approach is used. Information obtained can be retrieved and updated for bettering the management
of a given area. These can help support the sustainable development of natural resources and the
administration for the overall area of interest.
increasingly apparent that computer-based GIS provide the mean to the planning process for
conservation. However there still exists errors in the prediction particularly the values for each of
the USLE factors. The potential source of the modeling error is not only the values defined for each
factor but also in the scale and software uses.
