Economic comparison of an innovative method to qanat regeneration with conventional subterranean water supply for agriculture in the plains of Saadat Abad- Haji Abad city in Hormozgan province

Water resources are one of the most important resources in the continuity of life and socio – economic development. Without using of this valuable resource obtaining of growth and prosperity will be impossible to achieve. The study area (plain Saadat Abad) in Hormozgan province is located 140 km north of Bandar Abbas. In this area are 122 agricultural wells and two qanats. Due to high water withdrawals of water from wells and qanats aquifer levels rapidly decrease annually (approximately 0.6 M). So that water shortages are a serious problem felt. A number of active farmers have begun in collaboration and bank credit plan for the restoration and renovation of one of the canals. In this project as new initiative have been constructed a dam and transfer flood building for direction of 200 lit/s base flow to Parabedin qanat gallery. Then have been transferred water flood for irrigation of 800 hc follow area by dredging of qanat gallery. In order to economical evaluations of project have been compared water harvesting in this project with agricultural wells as usual method in the area. The results showed that with three levels (10%, 15% and 20% respectively) of the above price per cubic meter of water extraction by subterranean water wells less than the price farmers. Therefore, the implementation of development projects in addition to the economic justification would be to reduce flood damage, utilization of runoff, reclamation of arid lands to increase production and income of the agricultural sector to be effective.
