Abstract

Environmental considerations should be a priority for project implementers. Environmental impacts are one of the key pillars of sustainable development. This study examines the environmental assessment of the irrigation and drainage network in Varamin, located in Tehran Province. To achieve the research objective, significant positive and negative impacts resulting from the project implementation were identified and predicted using the ICOLD matrix. The environmental impact assessment matrix for the implementation option of the Varamin drainage network, along with the cumulative effects, is presented. The implementation option was evaluated in three phases: construction, operation, and post-impact mitigation measures. Of all the impacts, 32.88% pertained to the physical environment, 27.76% to the natural environment, and 39.36% to the socio-economic environment. The most significant positive impacts resulting from the implementation of the Varamin drainage network include 14 effects. After mitigation measures were taken, 2 effects were observed in the physical environment, 2 effects in the natural environment, and 2 effects in the socio-economic environment.
