Analysis of Drought Patterns in Azraq Depression (AD), During the Period (1984-2016)

The main goal of this research is to study the main morphometric, landscape characteristics depending on shuttle radar topography mission (SRTM) data for preparing digital elevation model (DEM), and monitor drought in Azraq depression (AD) applying three different methods including: SPI, by analyzing monthly rainfall records between 1984 - 2016 for 5 metrological stations. In addition to use inverse distance weighted (IDW); using Spatial Analyst Tools.tbx GIS.10.3 partically (Spatial interpolation), and normalized difference index of vegetation (NDVI) using Landsat (TM) images acquired in May 1984, and 2016. The main conclusions were reached: - 1. The dominated landforms are (valley and ridge), formed 72% from all six landforms classes. 2. Only 1.6% classified as extremely wet, and most of the years faced with a near normal with 64% from all the study period (1980-2016) 3. In general, the study area is characterized by drought; as the results show that only 3.3% from the study area have a yearly average rainfall from 161-190 mm. 4. Changes of NDVI (area and density) have decreased by -9% during the period of (1984-2016). Key words: Azraq depression DEM, SPI, IDW, NDVI.
