Abstract—Today, most people have settled in a habitat named city, a place with a distinct structure and function from its surroundings, which has created a new mean of civilization and human identity. Undoubtedly one of the most vital lifelines in modern societies is the water pipelines and its governing system In this regard, there should be a policy for purposive conveyance of water and providing the basic needs for citizens to manage the disorders and surmount the possible problems. What is responsible for this task is the water supply system and networks which should improve the life in societies Meanwhile, the knowledge of urban managers out of water systems status also seems a very vital issue because acquiring this knowledge they can take necessary action against unexpected disasters such as earthquakes. So, in this article, after doing several full dynamic finite element analyses on Qazvin distribution water pipelines, it has been tried to present the vulnerability maps of pipelines in the various hazard levels in the form of GIS maps to reach a general understanding of Qazvin water network status which located in a seismically active area and help the relevant authorities to take appropriate action on this issue. Keywords—Water transmission systems, urban management, earthquake, incremental dynamic analysis, GIS maps I. INTRODUCTION ver several human historic periods, secured access to water has been considered as the primary and basic condition for social and economic sustainable development and served as important factor in culture and civilization. According to hydrologists, water no longer serves as ample and economic valueless goods, but it is a commodity without substitute with high economic value in all production and consumption fields [3]. A systematic outlook of urban management toward the current urban system and its peerless importance in the present human’s life has provided the ground for addressing to any risk and threat, which may create problem in this regard. Among of them, the subject of earthquake and the underlying Mahdi Shadab Far is with the Civil and Transportation Engineering Department, Hohai University, Nanjing, China (e-mail: mahdishadabfar@yahoo.com). Zhang Qingping is with the Landscape Architecture Department, Nanjing Forestry University, Nanjing, China (e-mail: qpzh@njfu.edu.cn).

Inter alia, Iran has special and noticeable position in this sense for which Iran’s seismic status is in such a way that unfortunately over 90% of its total area as well as approximately 95% of Iranian cities are situated on seismic faults and or their adjacent regions. Earthquake is the most frightening natural weapon which can cause ground surface changes and consequently human civilization destruction. Meanwhile, urban water supply system is undoubtedly one of the most vulnerable lifelines in which a slight disturb can be led to a serious challenge [11, 14]. Qazvin city, which serves as center of Qazvin Province and one of the great cities in central Iran, has not been so far from this cycle and it is located on Iranian seismic belt. As it is explained in the following at this article, due to its location on the joint neck point among northern and western provinces of Iran, proximity to Tehran, and having several industrial areas as well as enjoying several important scientific centers including Qazvin Imam Khomeini International University, Qazvin University of Medical Sciences, and Qazvin Islamic Azad University, Qazvin possesses very important and crucial stand in this region [22]. Therefore, we will explain about the position of water transmission systems in urban administration areas in Qazvin City against the possible risks caused by earthquake and way of resistant construction of these systems against such risks. II. A REVIEW ON TECHNICAL LITERATURE Action and communication are the foundations of the human society and this principle highlights its place more and more in today’s world. In a world where communication has an important role, undoubtedly there are ways to make these connections. Apparently, the human societies are based on the urban framework and its systematic systems while the dominant communication lines form the highways of each city. Those lines start from the highways and introduce the narrow streets to the human community. To the extent that history shows the first hydrologic experiences were dated from Sumerian and Egyptians in the Middle East at ancient time so that date of dam- construction on Nile River is referred to 4000BC. At this time, similar activities had been done in Chinese Ancient Civilization as well and afterward in 1500BC for the first time water transfer pipelines have been used in Crete, Greece [15]. Then in 700 BC in Iran, some people dug aqueducts to transfer water to Seismic Analysis of Urban Water Supply Systems (Case Study: Qazvin City, Iran) Mahdi Shadab Far, Zhang Qingping, Reza Rasti, and Seyed J.
