Abstract

Drought has wreaked havoc to human societies throughout history and drought phenomenon is very complex as it is caused by a multitude of factors starting from the deficit of precipitation when compared to climatic mean. Such a deficit, when combined with sustained dry weather conditions entertain high evaporation and transpiration and thus result in soil moisture drought if there is no adequate irrigation. Finally, hydrological drought emerges by a combination of lack of precipitation and excessive use of available water resources for a sustained period. To assess historical droughts and to provide drought monitoring, various indices have been proposed for different purposes and using different datasets. Despite the panoply of these indices, when one focuses on the processes that caused droughts, a set of consistent indices may adequately describe the different aspects of the droughts.
