Assessing the 1990-91 California Drought

该项目将跟踪加州干旱第五年产生的快速变化的条件，并将收集否则可能丢失的数据。研究将集中在以下四个方面：a)获取和分析与干旱有关的气象和水文数据，以评估这次干旱事件的独特性；B)评估干旱监测程序，以确定如何有效地发现干旱的开始和评估干旱的进展；C)干旱对重大水利工程绩效的影响评价；d)评估异常应对措施的绩效，例如调水和水银行。这项工作的结果将使气候学家、水文学家、规划人员和管理人员以及来自政府、私营部门和学术界的研究人员受益。

The project will follow the rapidly changing conditions produced by the fifth year of drought in California and will collect data which otherwise would be lost. The study will focus on the following four areas: a) the acquisition and analysis of drought- related meteorological and hydrological data in order to assess the uniqueness of this drought episode; b) the assessment of the drought monitoring procedures in order to determine how efficiently the drought's beginning was detected and the drought's progression was evaluated; c) the assessment of the effect of the drought on the performance of major water resource engineering projects; and d) the assessment of the performance of unusual response measures, e.g., water transfers and water banking. The results of this work will benefit climatologists, hydrologists, planners and managers, and researchers from government, the private sector and academia.
