    Evaluation of Urban Water Distribution Network Resilience and Development of New Software based on Resilience Criteria Using Concurrent Discrete Event and Hydraulic Simulation(Case Study: Eslamshahr Water Distribution Network)

    , M.Sc. Thesis Sharif University of Technology Ebrahimi, Amir Hossein (Author) ; Mortaheb, Mohammad Mehdi (Supervisor) ; Hassani, Nemat (Co-Advisor)
    Abstract
    This dissertation proposes a new platform and a new software for evaluation of urban Water Distribution Network (WDN) resilience. Resilience is considerd as the ability of an infrastructure to come back to steady state after being affected by any environmental or man-made disturbance. WDN, as an essential infrastructure, has major role on resilience and sustainability of cities and communities. Today, uninterrupted performance of WDN is a basic need of people who live in cities. This uninterrupted performance becomes bolder in face of man-made or natural disasters like earthquake. The uninterrupted performance of a system is dependent on the system’s resilience. Majority of researchers... 

    Hydraulic Assessment of Seismic Resilience of Urban Water Supply Network

    , M.Sc. Thesis Sharif University of Technology Nasiri, Nastaran (Author) ; Safaie Nematollahi, Ammar (Supervisor) ; Mahsuli, Mojtaba (Co-Supervisor)
    Abstract
    The purpose of this study is to investigate the resilience of the urban water supply network against earthquakes, A hydraulic analysis of the water supply network was implemented in Rtx software to study the effective parameters in the resilience of the network. Rtx software is a tool for assessing the reliability and resilience of communities and infrastructure to natural hazards by taking into account related uncertainties. The water supply network, like other networks, is affected by earthquakes. The seismic damage varies depending on the vulnerability of the network, the intensity of the earthquake, the focal depth, and the distance from the epicenter. Thus, it reduces the ability of the... 

    Probabilistic Modeling of Water Distribution Infrastructure and Its Inter- Dependencies in Community Resilience Analysis

    , M.Sc. Thesis Sharif University of Technology Khayambashi, Kamiar (Author) ; Mahsuli, Mojtaba (Supervisor) ; Safaie, Ammar (Co-Supervisor)
    Abstract
    This research develops a probabilistic framework for evaluating community resilience subject to earthquake events by modeling the water distribution system and its prevailing inter- and intra-dependencies with other infrastructure systems of the community. This framework is entitled “Rtx,” which is under continuous development at the Center for Infrastructure Sustainability and Resilience Research (INSURER) at Sharif University of Technology, Tehran, Iran. It quantifies the community resilience by integrating hazard models, risk models, and recovery models within an agent-based simulation. Comprehensive modeling of the water distribution system requires a library of probabilistic models,... 

    Multi-criteria decision making for integrated urban water management

    , Article Water Resources Management ; Volume 22, Issue 8 , 2008 , Pages 1017-1029 ; 09204741 (ISSN) Zarghami, M ; Abrishamchi, A ; Ardakanian, R ; Sharif University of Technology

    Abstract
    The city of Zahedan, in South-eastern Iran, has high population growth, limited local freshwater resources and inadequate water distribution system resulting in water supply failures in recent years. This paper will investigate integration of several demand management measures such as leakage detection on water distribution network, water metering and low volume water fixtures as well as the conjunctive use of surface and groundwater resources of this city. For integration of water management criteria, compromise programming will be used as a multi-objective decision making method. The criteria include minimizing the cost, maximizing water supply and minimizing the social hazards due to the...
