Using System Dynamics Method to Determine the Effect of Water Demand Priorities on Downstream Flow

Optimal Operation of Hydropower Reservoirs under Climate Change: The Case of Tekeze Reservoir, Eastern Nile

“…Currently, due to water crisis the global freshwater supply to meet the needs of the different sectors is falling short [5][6][7]. Factors that contribute to this include population growth, urbanization, climate change, land use change, land degradation and poor water resources management [8,9]. Hence, to alleviate these problems and meet the freshwater and energy demand of communities, it will necessitate optimal operation of water resources reservoirs [10,11].…”

Incorporating Social System Dynamics in the Columbia River Basin: Food-Energy-Water Resilience and Sustainability Modeling in the Yakima River Basin

“…While built upon clearly limiting assumptions, this serves to highlight the fundamental social interactions that are at the basis of the FEW nexus. Other modeling efforts show that while increased water utilization could encourage the development and growth of a community (Loops R1, R2, R3), this is limited by resource availability (Ghashghaie et al, 2014) which in this case is demonstrated through the reservoir water balancing loop (B1). Figure 4 represents our attempt to build on these previous models and incorporate attention to the social as both input and output of FEW system mapping.…”

“…As such, these general, visual representations of a system are particularly useful for developing and building consensus around how a system is thought to behave (Stave, 2003), and bridging divides in interdisciplinary research (Stuart, 2016). Conceptual maps have been used to bring more explicit attention to social, community, and ecosystem service factors and to highlight composition and competition of communities (Nandalal and Simonovic, 2003), limitations and constraints due to environmental resources (Ghashghaie et al, 2014), co-dependent FEW security needs (Ericksen, 2008), and considerations related to governance, labor, poverty, and population fluctuations (Flora et al, 2004). Conceptual mapping can be a first step toward more precise modeling efforts.…”

“…For example, in Figure 4 one section of the conceptual map indicates how governance plays a role in introducing policies that ultimately negotiate and prioritize FEW security of various stakeholders as well as how their satisfaction and aspirations (e.g., livelihood, well-being) create feedbacks. Starting with archetypes of resource allocation (Loops B1, R1,R2,R3) and combining with resource conflict (Loops B2, B3) demonstrates a adjustable, specific, and reproducible methodology that has been called for in nexus assessment (Ghashghaie et al, 2014;Albrecht et al, 2018).…”

A Novel Integrated Decision Support Tool for Sustainable Water Resources Management in Singapore: Synergies Between System Dynamics and Analytic Hierarchy Process

“…This method has been widely used in water resources planning and management (Winz et al 2009 and references therein). For example, SD has been used to study water resources in Canada (Simonovic 2002a, b;Simonovic and Rajasekaram 2004;Ahmad and Simonovic 2006), in China (Dai et al 1992;Xu et al 2002;Yang et al 2014), in Spain (Fernandez and Selma 2003), and in Iran (Madani and Mariño 2009;Ghashghaei et al 2013;Ghashghaie et al 2014). Its capabilities to quantitatively simulate the dynamic consequences of various policies make it an ideal decision support tool for strategic policy testing and selection.…”
