Abstract:

As the water distribution network as a last resort in the urban water cycle is directly related to the subscribers,the changes in the quality and quantity of drinking water may have adverse human, socio-economicand physical consequences in the shortest time after the crisis. One of the most important measures to reduce thenegative consequences of the occurrence of human-made threats, natural events and inherent accidents in urbanwater networks is to have a plan that is in accordance with the principles of non-operational defense. In this regard,the present study was designed to provide urban water network design model in order to provide sustainabilityagainst potential crises. In this paper, four models (serial, branch, ring and composite) are presented for networkdesign. By identifying 11 models of urbanization and their adaptation to water network models, six models(radial, circular, spider, network, satellite, and galactic) To design the optimal water network. Considering seveninertial defenses (diminishing, networking, consolidating, storing, balancing, dispersing and replacing), selectedurban models are designed to design a water grid around the four main axes (reducing the probability of occurrenceof threats, decreasing the vulnerability, reducing the speed to Normal conditions and ease of managementof emergencies (which include a total of 168 different modes) were evaluated. According to the results, the theoreticalframework of the model was formulated and its main axes were determined. In the following, identifying34 characteristics for the proposed model, 14 patterns of innovation were introduced, in the end, by designing thepublic view, the urban water network design pattern was developed to provide sustainable water supply againstthreats and with a neighborhood-oriented approach.
