Environmental Risk Assessment of Balaroud Dam of Khuzestan`s construction Using Analytical Hierarchy Process

This study attempts to determine and assess the Risks due Construction of Balaroud Dam.After the recognition of the activities and the environment of the field under the study with regard to the magnitude of the effects, the likelihood of the possible consequences for humans, the environment and the working equipments were identified and the classification of the risks based on the delfi method was conducted and the risk-creating factors were classified naturally, biophysically, and anthropogenically. The methodology used was analytical Hierarchy Process. After the creation of the hierarchy of risks; paired comparison matrices were formed with regard to the risk of danger and effect magnitude. Moreover, to obtain the relative and final weight of each of these factors, preferences amounts were given to the expert choice software. results show that cut and fills with the final weight of 0. 277 is the most import risk in the region. Also, drilling and explosion with the final weights of 0.60 and 0.111 are of second and third priority. Other factors are lower in priority. Measures to control and reduce risks are alsoprovided.
