After identifying the risks, analyzing and ranking them was done by using TOPSIS. Analytical Hierarchy Process (AHP) was used for determining occurrence probability and Environment Failure Mode and Effect Analysis (EFMEA) were used for determining other criteria. Results shown that risk of drought and low water of wetland and Construction of Zayandehrood damwere the first to second in priorities. After determining the risk priority number by TOPSIS, risk levels were determine that show the priorities of management to control the risks. The advantage of TOPSIS in environmental risk assessment is ranking of risk by different criteria.
