The Effect of Land Suitability to Reduce Erosion Risks, Using GIS (Case Study; Boushehr Province, Iran)
K. Soleimani and S. Modallaldoust

Soil erosion normally occurs at a very high level in most parts of Iran and can become a problem when human affects such as agricultural activities disturbed the ecological balance. Problems with erosion have become more apparent in recent decades owing to changes in land use, field sizes and soil management patterns. This study aims to find the relations between land management such as slope gradient with land use pattern and the erosion reduction in Jam and Riz basin. The materials used in this study included the basic maps of topography, geology, recent land use and IRS data that prepared the required information layers to assessment of erosion. The types of especial erosion calculated by the empirical method for the mentioned basin. The land use coefficient (Xa) was applied in the used model of EPM (Erosion Potential Model) to forecasting the effect of the land type to reduce the erosion. The results of this study indicated that the rangeland products a rate of especial erosion about 3074.8 (m3/km2 year) and the cropland products a rate of especial erosion about 1714.4 (m3/km2 year) which are respectively have minimum and maximum role in erosion for the study domain. In conclusion optimum land management reduced erosion in the study area up to 58.3%.
