Abstract

Sustainability of water supply networks should be based on the risks of water hammer phenomenon. The purpose of this study is to provide a new approach to the analysis of water hammer phenomenon in the water supply network. By conventional methods, the damage because of water hammer is estimated based on the maximum pressure at nodes. However, during this phenomenon continuation and changing of water hammer in overtime is ignored. In this study, quantitative parameters, to evaluate the network performance will be assessed under the water hammer phenomenon. Hence, the information through the parameters of reliability, resilience, vulnerability and their composition, sustainability parameters are analyzed. However, numerical analysis of water hammer phenomenon caused by sudden pump stop was done using HAMMER software. The results showed that the sustainability parameter can be used to evaluate the efficiency of water networks. In the event of water hammer phenomenon 4.83 percent of points of the studied network had sustainability factor less than one. So that use of protective structures increases sustainability parameter in most zones and this amount are 1.11 percent of the network nodes. Moreover, increasing and decreasing of Hazen coefficient and pipe diameter increases and decreases the sustainability parameter, respectively.
