Markazi Province have arid and semi-arid climatic. Lack of soil moisture is one of the factors limiting the growth of productive plants during the dry period. One of the basic strategies to deal with these challenges is feasibility growth of plants during drought periodand conserve soil and water resources, proper soil and water resources management in the watershed. System of rainwater is an effective solution to achieve the above objectives. The aim of this research is to compare of three types of systems to collect rain water requirement in order to develop dryland orchards of almond in the steep lands of Khosbyjan in Arak. Therefore, in this study, three types of systems include insulation, natural pasture and cleanranch were chosen. each treatment was repeated four times.The area of the system was 15 meters square. At the end of each plot, runoff collecting and measuringequipment were put. During the project 95 rainfalls occured that measured 35 above 10 mm which created runoff. The results showed that average annual runoff respectively for pasture, clean pasture and insulated are 110,130,2044 liters and average collected water per square meter per year, respectively were 6,8 and 136 liters. Insulated system have highly efficiency for rainwater harvesting and providing water requirement in order to develop almond orchards in sloping dryland.
