چکیده
Lifelines are the determining components of survival in today's modern world and if the service of these infrastructures is threatened or destroyed due to natural disasters (especially earthquakes) and military threats, the activities of the society are disrupted and the severe failure of these systems will prolong the reconstruction period. One of the most important vital infrastructures that has a direct relationship with people's lives is the need for a water network. A review of the past earthquakes of the world and Iran shows that the components of the drinking and non-drinking water supply system have historically been considerably poor. The main goal of this paper is to prepare a model to analyze the seismic vulnerability of the water network by considering its dependence on other networks. To determine the vulnerability analysis of the water network by considering dependencies, two models were used, graph theory and Leontief. Then, after drawing the network architecture, the proximity and uncertainty matrix of all features were extracted. By multiplying the transpose of the uncertainty matrix in the independent damage analysis of each feature, the dependent damage was determined. The analysis showed the significant impact of dependence on the damage estimate of water network infrastructure; in some elements, the damage increased up to 45 times compared to the independent state. The risk of water reservoirs, water pumping stations, and water wells increased by 92%, 87%, and 62%, respectively, from the independent situation compared to the dependence in the studied area. In the case of robustness of the water network compared to the current situation, the vulnerability of water tanks, water pumping stations, and water wells will be reduced by 25%, 22% and 32%, respectively.

Lifelines are the determining components of survival in today's modern world and if the service of these infrastructures is threatened or destroyed due to natural disasters (especially earthquakes) and military threats, the activities of the society are disrupted and the severe failure of these systems will prolong the reconstruction period. One of the most important vital infrastructures that has a direct relationship with people's lives is the need for a water network. A review of the past earthquakes of the world and Iran shows that the components of the drinking and non-drinking water supply system have historically been considerably poor. The main goal of this paper is to prepare a model to analyze the seismic vulnerability of the water network by considering its dependence on other networks. To determine the vulnerability analysis of the water network by considering dependencies, two models were used, graph theory and Leontief. Then, after drawing the network architecture, the proximity and uncertainty matrix of all features were extracted. By multiplying the transpose of the uncertainty matrix in the independent damage analysis of each feature, the dependent damage was determined. The analysis showed the significant impact of dependence on the damage estimate of water network infrastructure; in some elements, the damage increased up to 45 times compared to the independent state. The risk of water reservoirs, water pumping stations, and water wells increased by 92%, 87%, and 62%, respectively, from the independent situation compared to the dependence in the studied area. In the case of robustness of the water network compared to the current situation, the vulnerability of water tanks, water pumping stations, and water wells will be reduced by 25%, 22% and 32%, respectively.
