The risk of water erosion is one of the main
environmental concerns in the southern Mediterranean regions. Thus,
quantification of soil loss is an important issue for soil and water
conservation managers. The objective of this paper is to examine the
applicability of the Soil and Water Assessment Tool (SWAT) model
in The Sarrath river catchment, North of Tunisia, and to identify the
most vulnerable areas in order to help manager implement an
effective management program. The spatial analysis of the results
shows that 7 of the catchment experiences very high erosion risk,
in need for suitable conservation measures to be adopted on a priority
basis. The spatial distribution of erosion risk classes estimated 3
high, 5,4 tolerable, and 84,6 low. Among the 27 delineated subcatchments
only 4 subcatchments are found to be under high and
very high soil loss group, two subcatchments fell under moderate
soil loss group, whereas other subcatchments are under low soil loss
group.
