In other words, each of spreading projects implemented in different stations have specific economical effects in desired area. The goal of this project is determination of economical effects of floodwater spreading project on Dehloran aquifer through monitoring and surveying its behavior and recording relevant data steadily. For this purpose, profit ability and economical justification of the project have been determined through economical indicator evaluation of projects. Results demonstrated that irrigated lands of downstream villages have been inceased 3.5 times in 2010 compared to the year1995. The added value of the injected floodwater was estimated to be 14.6 billionRial. The added value of rangeland products was about 1353.96 billion Rial. The added value of wood production was estimated about 13.38 billion Rial. The added value of agricultual products was about 657.05 billion Rial. NPV, ROR and B/C of the project were 1398.61 billion Rial, 0.38 and 2.87, respectively that show economical justification of the project.
