Scenario-Based Sustainability Assessment to Provide Interactive Decision Support for the Long-Term Transition of Urban Water Supply Systems

摘要: This dissertation focuses on the evaluation of technical and environmental sustainability water distribution systems based scenario analysis. The decision support system is created to assist in making-process visualize results assessment for current future populations scenarios. First, a methodology developed assess Then, scenarios are produced evaluate alternative solutions as well demand variations. Finally, proposed using combination several visualization approaches increase data readability robustness evaluations system. The measured index which reliability, resiliency vulnerability performance criteria. Hydraulic efficiency quality requirements represented nodal pressure age parameters, respectively. U.S. Environmental Protection Agency EPANET software used simulate hydraulic (i.e. pressure) age) analysis case study. In addition, network evaluated “total fresh use” energy intensity” indicators. For each scenario, multi-criteria combine criteria study area. The first applied baseline system). Critical locations where problems occur identified. There two major options that considered at these critical locations. These focus creating order test verify rather than obtaining best solution systems. traditional approach quality. includes additional components such booster pumps, valves etc. second reclaimed supply meet non-potable fire flow. flow simulation specifically included since regulations have significant impact urban infrastructure design. Eliminating need from potable would saving resources reduce detention times. The effectively compare with other. powerful tool conduct but purposes capabilities limited. Therefore, this dissertation, simulations completed visualized by combining techniques provide better readability. technique introduced here small multiple maps instead animation parameters. eliminates change blindness provides easy comparison time steps. procedure aggregate nodes along edges simplify network. A circle view values single parameter or age). third fitting into grid representation assists eliminating irregular geographic improves visibility view. prototype an interactive population Interactive tools enable analyzing aggregated information about
