Application of Water Resources System Dynamics Modeling to Climate Change Impact Assessment for Sustainable Rural Community

Under the impact of climate change, water resources management meets seriously problems. In order to response the impacts on water resources caused by climate change, the research topic regarding multiple water resources receives many attentions. In addition to traditional water resources, new water resources may raise the water use efficiency and reduce the demand loadings on the external water supply systems. Therefore, sustainable rural community can install reuse system and constructed wetland to provide harvested rainwater and reclaimed water as a distributed water supply system. For managing the water resources system in a rural community, the development of simulation model can provide information on water resources management. In this study, the water resource system dynamics model is applied to impact assessment of climate change, and the indicator system is used in evaluating the vulnerability and resilience of water resources system under climate change. The factors lead model uncertainty and high sensitively is identified. Overall, they are further used to evaluate the adaptive capacity of a rural community installing reuse system and constructed wetland under climate change. According the results, adaptation measures can be provided for adjusting water management strategies, which can let sustainable rural community have stable water supply under climate change. Besides, the results provide suggestions regarding an appropriate water resources distribution in a rural community. At last, this study also addresses the requirements for the future research to assess the optimal design for sustainable rural community.
