System dynamics modeling approach to water supply system

Abstract

A water supply system is a comprehensive system including the components of water users, sources, treatment plants, and transportation measures. The complex nature of a water supply system, however, has made hard to develop and evaluate a comprehensive and generic water supply system model. In this study, a generic water supply system model is used to evaluate water sustainability for a hypothetical system in the semi-arid area. An environment for object-oriented system dynamics model allows the decision maker to develop a model that can be understood easily by the stakeholder and non-modeler. The modular structure of the generic water supply system also allows for integration of a site specific model by combining modules which a modeler may wish to have in the system. Imported and reclaimed waters to support groundwater as alternative water sources are evaluated in the hypothetical system in this study. As a result, alternative water sources demonstrate an important role to maintain water sustainability of the system when groundwater is the main source.

Water and energy-based optimisation of a “MiniCity”: A system dynamics approach

“…The use of SD to address challenges associated with urban water supply is increasing within the international water sector (Sahin et al, 2018;Bertone et al, 2016;Park et al, 2014;Rehan et al, 2014). The generic water demand-supply system developed by Chung et al (2008) has been tailored based on the MiniCity's need. This system simulates water flows to meet water demands.…”

Performance Assessment of a Water Supply System under the Impact of Climate Change and Droughts: Case Study of the Washington Metropolitan Area

“…Water resources are modeled at many scales. Various global water models and water scarcity studies have been conducted (Saysel et al 2000;Alcamo and Henrichs 2002;Chung et al 2008;Kojiri et al 2008). Hanasaki et al (2013a, b) in their two-part study assessed water scarcity using global hydrological models and the latest global change scenarios.…”

“…These tools are often specific to a system and difficult to adapt to other systems. Furthermore, some lack a user-friendly interface (Chung et al 2008).…”

“…This complexity makes it difficult to develop a comprehensive mitigation and adaptation strategy that appeals to all stakeholders and policy makers and to educate the public about the elements that may cause a water supply and demand system to lose reliability due to droughts, population increase, aging water infrastructure, and climate change. Therefore, simulation and modeling approaches that can represent a water supply and demand system with its components and that can demonstrate the effects of management policy interventions can be extremely valuable (Chung et al 2008).…”

The Integrated Management of Water Resources in Marina Baja (Alicante, Spain). A Simultaneous Equation Model

“…Residential water use models with agent based simulations (Chu et al 2009;Berger et al 2007), multi-criteria applications (e.g. Gómez-Limón and Martínez 2006;Hajkowicz and Collins 2007;Hajkowicz and Higgins 2008;Higgins et al 2008;Zarghami et al 2008), dynamic simulation models (Rogers and Fiering 1986;Simonovic and Rajasekaram 2004;Chung et al 2008;Winz et al 2009), conceptual models using flow diagrams (Bhakdisongkhram et al 2007), net-back analysis, hedonic and optimization models (Massarutto 2001), and of course, GIS models, basically for groundwater and irrigation management (e.g. Chowdary et al 2009;De Lange et al 2010) and even in the same study area Peña et al 2005), or a combination of different techniques e.g.…”
