This research has examined the local knowledge of traditional irrigation in the city of Bojistan by descriptive-analytical method. The method of data collection, field and library, and villages over 100 households in the city have been studied for the sustainability of water resources. The results of the research showed that the use of indigenous knowledge in water resources management has been able to minimize the problems caused by seasonal changes in temperature and its impact on the water resources deficit in the research area.
