Environmental Impact Assessment of Irrigation Network Implementation on Triple Environments

The present study investigates the EIA on the implementation of Shahriyar Dam irrigation network design on the physical, biological, and social, economic and cultural components. In this research, the Leopold matrix method is used for EIA. This method can be cost effective in time, cost and volume due to quantitative design results. One of the important innovations of this research is in the type of the case study. In this study, the environmental impacts assessment of irrigation network of Shahriar dam is evaluated. This network is intended to compensate for part of agricultural land damage that is submerged in Shahriar dam reservoir. Obviously, the main purpose of the dam construction is to save about 700 million cubic meters of water for the Gilan and Foumanat irrigation network and somehow it plays an important role for the Sefidrud dam. In short, less than 10% of the dam reservoir volume is allocated to irrigation network water supply.
