Erosion at the place of occurrence causing soil degradation and decrease its quality by changing physical, chemical and biological characteristics. Soil erosion is one of the most serious natural problems, which effects many of the ecosystems in arid and semi-arid areas in the world. Separation of soil particles by raindrops and its transfer by runoff, are two main processes of soil erosion. Due to the destructive and important role of the rain drops in the soil erosion, it is essential to carry out extensive activities in terms of research and implementation. In this regard rain simulating has been used widely in understanding the erosion and associated processes with it, however our country is considered a young country from research in this field. The soil mass to some extent has been resisting against external forces and then it is disjointed. Soil disjoint usually is a shear type. The maximum resistance of the soil against shear stress called shear resistance. The result of this research about the soil of arid and semi-arid areas management from the point of view of keeping water in the soil and mechanical resistance and stability against corrosive factors, and also study of the effect of soil erosion specially the combined effect of it with rainfall intensity on erosion processes, runoff, soil erosion, sediment production and also its effect of soil physical parameters for recognition and simulation of the soil response will be necessary. This research done for sand mixtures with zeolite, phlogopite, bentonite, kaolinite clay minerals and clay soil. The effect of these clay minerals on soil erosion and shear strength checked out the most spray in different percentage of clay-sand mixtures is for lower percentage of clay. Clay-sand mixtures with 15% clay had the most erosion rate and clay-sand mixtures with 45% clay had the least erosion rate. This results indicated that with increasing in the amount of clay in the soil the adhesion of it increases and the erosion of it decreases. The results showed that as the humidity increase, the amount of erosion will also increase. Moisture increase to a plastic limit conditions causes the bonds between soil particles and water and increases adhesion. When the moisture reach to the liquid limit this bonds weakened and increases the erosion rate. The dry conditions is between the other two. Drying and wetting cycles decreases the erosion and increases the adhesion rate. The relationship between shear strength and erosion shows that with increasing in the amount of shear strength, the erosion rate decreases.
