Abstract

This research is intended to characterize drought intensity, duration, and areal extent of meteorological drought in the Awash River basin. Using rainfall data and evapotranspiration data is useful to determine the spatial distribution and characteristics of drought and understanding the characteristics is important for monitoring and establishing an early warning system. Reconnaissance Drought Index (RDI) was used for the identification of drought conditions, Mann-Kendall test is used for determining the trend, and ArcGIS is used to analyze the areal extent of drought in the Awash River Basin.
