Economic assessment of flood spreading on water resources and agriculture (Case Study: Moosian Plain, Dehloran Township)

Floods control, artificial recharge of ground water aquifers, and attempt to optimize the efficiency of water and soil resources are the most important benefits that have been achieved as a result the construction of flood spreading stations in the country. The aim of this research is assessment and determination of economic effects of flood spreading project on water resources and agriculture by monitoring and recording relevant data steadily and continuously. For this purpose, profitability and economic justification of the project were studied using proper criteria of economical evaluation of investment projects. The results showed that water cultivation area of downstream villages of project have been 3.5 folds more compared to the year 2013. Moreover, the added value of the injected flood based on measuring the volume of controlled flood was estimated to be 14.6 Million Rials. The added value of grassland production project became 1354 Million Rials. Whereas, the added values of wood production and agriculture section were estimated to be 13.4 and 657 Million Rials respectively. Economic evaluation indicators of project (NPV, ROR, and B/C) were estimated to be 1399 Million Rials, 0.38, and 2.87 respectively showing economic justification of project.
