ABSTRACT

Soil erosion is a process threatening natural resources such as water, soil, plant cover
and climate both directly and indirectly and it is dangerous for human safety and his
life. Erosion not only weakens soil, makes useless farms and a lot of damage, but also
causes harm by sedimentation solid of materials in streams, sources, dams, ports and
decreases the amount of their capacity.

In this project, we are studying soil erosion in Mousa Abad basin in Tiran, Isfahan in
SLEMSA model using GIS. In this research, the factors and elements affecting erosion
were studied using the capabilities of the model. To do so, we used data, local studies,
map combination and interpolation.

We can find an index to calculate the difference between potential and practical erosion
through estimating the erosion rate, identifying the reasons and kind of erosion as well
as erosion hazards.

Keywords: SLEMSA model, Erosion, Environment Protection, Mousa Abad
