| 1 | An Analysis of Groundwater in Sinjar Plain (Northwest of Iraq) Using WQI Model显示文摘Sinjar plain-northwest Iraq has an abundant amount of groundwater. Due to the importance of this water source, the water quality index (WQI) model was used in the classification of groundwater in the western and eastern regions of Sinjar plain for beneficial use. Groundwater samples were chemically analyzed to calculate the values of WQI. This model consists of a single number of the integrated deviation from standard quality, which indicates the relative importance of each relevant variable for beneficial use. The results indicate that the WQI could be used to determine the particular uses of groundwater. The groundwater in the Sinjar plain is more suitable for irrigation than for livestock drinking and domestic use. | Bassam F Al Bassam Ayad M Fadhil Faculty of Earth Resources , China University of Geosciences , Wuhan 430074 | 2001 | Journal of China University of Geosciences2001，12，4： | 2 |

| 9 | Drought trend analysis in a semi-arid area of Iraq based on Normalized Difference Vegetation Index, Normalized Difference Water Index and Standardized Precipitation Index显示文摘Drought was a severe recurring phenomenon in Iraq over the past two decades due to climate change despite the fact that Iraq has been one of the most water-rich countries in the Middle East in the past.The Iraqi Kurdistan Region(IKR)is located in the north of Iraq,which has also suffered from extreme drought.In this study,the drought severity status in Sulaimaniyah Province,one of four provinces of the IKR,was investigated for the years from 1998 to 2017.Thus,Landsat time series dataset,including 40 images,were downloaded and used in this study.The Normalized Difference Vegetation Index(NDVI)and the Normalized Difference Water Index(NDWI)were utilized as spectral-based drought indices and the Standardized Precipitation Index(SPI)was employed as a meteorological-based drought index,to assess the drought severity and analyse the changes of vegetative cover and water bodies.The study area experienced precipitation deficiency and severe drought in 1999,2000,2008,2009,and 2012.Study findings also revealed a drop in the vegetative cover by 33.3%in the year 2000.Furthermore,the most significant shrinkage in water bodies was observed in the Lake Darbandikhan(LDK),which lost 40.5%of its total surface area in 2009.The statistical analyses revealed that precipitation was significantly positively correlated with the SPI and the surface area of the LDK(correlation coefficients of 0.92 and 0.72,respectively).The relationship between SPI and NDVI-based vegetation cover was positive but not significant.Low precipitation did not always correspond to vegetative drought;the delay of the effect of precipitation on NDVI was one year. | Ayad M F AL-QURAISHI Heman A GAZNAYEE Mattia CRESPI | 2021 | Journal of Arid Land2021，13，4： | 1 |
