Determining the effectiveness of flood spreading schemes, especially from the point of view of effective economic and social indicators, over a quarter century after their implementation in the country, plays an important role in their assessment. In this study, indicators related to the effects of flood spreading plans on Ab-Barik Aquifer of Bam were identified and then ranked based on nonparametric statistical tests from the experts' point of view. For this purpose, first the indicators related to the effects of flood spreading projects on the aquifer based on library studies, expert inquiries as well as site visits and face-to-face interviews with local residents and users were identified and finally the validity of the questionnaire based on expert opinions was identified. Finally, the validity of the questionnaire based on the experts' opinions and their comments was finally confirmed. Also, the reliability of the measuring instrument was tested by calculating Cronbach's alpha component. In this research, based on the multi-response coding method, the variables of the questionnaire were of the type of qualitative and qualitative variables consistent with the Likert scale, so at this stage, a survey was conducted from 30 experts. The range of changes in mean rank values varies from 4.15 to 22.88. The results of the ranking of indices based on Friedman test showed a significant difference in the effectiveness of the effective variables in evaluating flood spreading projects on aquifer, so that the question of “reducing the damage to flood lands and gardens” with the rank mean of 22.88 and also the question of “conflicting among the villagers in the area” with the rank mean of 4.15 have maximum and minimum priority, respectively. In addition, the results of the study indicate the high effectiveness of flood spreading schemes in the Ab-Barik Aquifer of Bam.

Flood control, artifcial feeding of ground water aquifers and effort to optimize the productivity of natural resources are component the most results that have gotten from implementation of spreading project in spreading statious of country. One of the most important goals of spreading is the creation of positive changes in economical variables of area including agricultural and rangeland productionsand their development. 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.
