The soil water erosion risk is one of the most important problems and challenges facing the agricultural process in the Syrian coast at present, especially those areas surrounding rivers and water leaks.

This study aims to classify soil erosion risk based on co-ordination of Information on the Environment (COREIN) model for the near and middle basin part of the Northern Al-Kabeer River (Lattakia province).

To achieve this objective, the first phase of the study was to evaluate the soil erosion viability by estimating soil texture, soil depth and stoniness percentage.

Consequently, soil erosion viabilities were classified according to their influencing degree in soil erosion.

The potential risk erosion map was based on crossing all information obtained from soil erodibility, erosivity index and the degree of slope on study area by using GIS technologies.

The land cover map of study area was produced and classified to two classes depending on soil protection degree.

Then, an actual risk map of soil erosion was prepared after crossing land cover and potential risk erosion classes of study sites.

The results showed that 2.47% of the study area facing high risk of soil erosion, while the soil risk was moderate in 22.18% and low in 75.35% of the study area.

The high risk erosion spots are mainly located in the center and northern parts of the study area.

Moreover, the study confirmed that the land cover is the most influential factor in soil water erosion, which reduced about 60.93% of the high risk of potential soil erosion.
