Abstract
It is awared that decreasing precipitation of recent years has propelled a declining safety of water in urban areas. As a countermeasure, efforts are focused on expanding the use of existing water resources, and refining sea water for general use. In order to execute these policies, it is necessary to evaluate quantitatively the safety aspects maintained at each local government concerned with water management, in assessing the drought scenario. In this article, for evaluating the water system safety, reliability, resiliency, vulnerability, and also additional DRI (Drought Risk Index) are defined. Further, ACity, as our hypothetical study area, is examined for the effects of remedial policies for drought in the surrounding local governments during those droughts in years 1992 and 1994.
