Sustainable Water Management Solutions for Large Cities (Proceedings of symposium S2 held during the Seventh IAHS Scientific Assembly at Foz do Iguaçu, Brazil, April 2005). IAHS Publ. 293, 2005, 105-108

Abstract With China’s rapid population increase and economic growth, more and more large cities in China are facing aggravated water scarcity. Therefore, there is an urgent need to assess water scarcity in large cities. This paper selected Luoyang City, China, as a case study site and proposed six types of assessment indicators for assessing Luoyang’s water scarcity. By means of a two-order fuzzy comprehensive judgment method, Luoyang’s water scarcity was graded and the impact of each type of assessment indicator was rated on water scarcity. The results provide a scientific basis for the sustainable exploitation, utilization and management of water resources.
