For many years it has been assumed that control and spreading the flood water in aquifers causes changes in the quantity and quality of underground water, economic exploitation, chemical and physical properties of the soil, and existing patterns of agriculture as well as reduction in social antagonism, and soil infiltration. According to this assumption, we made a hypothesis that was tested by evaluating the results of flood water spreading in arid and semi arid stations in Iran. A comparative analysis was implemented to evaluate the results obtained from the check and treated areas. Results showed that the flood water spreading caused a reduction in social antagonism, vegetation in the last years and soil infiltration as well as an increase in the soil fertility, underground water, income, and vegetation in the beginning years.
