Abstract

The analysis of correlation of various hydrologic measures such as precipitation, temperature, streamflow, reservoir level, and ground water level data as drought indicators; and their influence in the evaluation and analysis of different stages of drought severity was the main focus of the study. This paper presents the findings of the study by using one of the hydrologic indicators - ground water availability. The concept of truncation levels of different drought indicators was introduced to distinguish drought events from their historic records. An evaluation procedure was developed to define drought severity by aggregation of truncation level, drought duration and conditional probability. Consequently, drought duration and conditional probabilities were proposed in correspondence with associated drought events
