Drought considered from the most natural hazards that threatened the West Bank water resources and very critical issue to understand. This study aims at assessing the behavior of spatial and temporal drought in the West Bank. In order to study drought, it is important to correlate it with rainfall analysis. Also this study shows the effects and features of drought and discussing them depending on spatial and temporal analysis.
The drought changes along West Bank temporally and spatially. Hence the drought features must be considered for all water resources management in the West Bank. Most of formulas of drought prediction are based on statistical analysis, because drought is treated as random and probability is the main way to deal with drought.
Rainfall data is an essential element of basic data input to many hydrologic and engineering studies. The West Bank is characterized as a arid to semi-arid region with rainfall varies spatially from one station to another and temporally at specific station on many factors.
