Modeling and Analysis of Water Resources System Problems by Using the Causal Feedback Loop Diagram of System Dynamics

Authors: , ,

Abstract: To the work of modeling and analysis of water resources system problems, it is hard to realize completely the structure and behavior of a system just from a system diagram, flowchart, or the outcomes of a software simulation. With a causal feedback loop diagram of system dynamics, the casual interactive relationships among model variables and parameters can be revealed to elucidate the nature of impact dynamics and feedback, portraying information feedback in a system. Therefore, in this paper, the causal feedback loop diagram of system dynamics was briefly described and the feedback characteristics within a system was identified by using the technique of causal feedback loop diagram through two case studies of a general reservoir operation problem and a water resources system capacity-expansion planning. According to scenario results and analysis, a causal feedback loop diagram of system dynamics is one approach that can help decision maker to better grasp the structure and characteristics of a system.
