Abstract
Beijing, the capital of China, has a fast-growing economy but is known for water scarcity. Therefore, relieving plans such as wastewater utilization and South-to-North-Transfer are implemented. Therefore, relationships are complicated among components in Beijing’s water supply-and-demand system. Maintaining the water balance in Beijing is crucial both economically and politically. However, few have directly addressed the problem systematically recently. Therefore, the system dynamics (SD) approach is applied for modeling of the water supply-and-demand system. The objective is to investigate and forecast water balance, and to identify and propose solutions for potential challenges. The SD approach is a popular computer-aided systematic method for investigating intricate behaviors of complicated systems. A serious water shortage in Beijing in a few years is forecast because current relieving plans will reach their limits. Restricting certain water demands and improving water reclamation is recommended. There is an urgent need to develop and implement sustainable methods for Beijing.
