| Abstract | ||
| The study aimed to follow up the drought situation and the effectiveness of geospatial technologies in monitoring this phenomenon. The indexes and indicators of SPI, NDVI, VCI, TCI, VHI and WSVI were used to monitor the drought situation starting from 1999-2019 for soils within the western desert of Iraq in the Sakran region. The climatic drought index SPI showed that the region was affected by the drought condition with recurrence at intervals ranging every 5 years, while the WSVI hydrological index indicated that the region was affected by the drought condition and its variation from year to year with the predominance of moderate and severe drought. The results of the agricultural drought indices NDVI, VCI, TCI and VHI agreed with other evidence in terms of the region's affected by the state of drought, which was classified into five types whose areas of impact varied with the selected years of study with the predominance of severe dry cases. | ||
