Groundwater detection and classification using remote sensing and GIS in Najaf, Iraq

• Due to the shortage of fresh surface water caused by climate change, groundwater has become a vital water supply for household, agricultural, and industrial use. Alternative methods for determining groundwater depth, amount, and quality at a lower cost and less effort are critical. This study aims to determine the depth and kind of groundwater in Najaf City, Iraq, using Aqua detector remote sensing device. Thirty-nine sample locations were chosen in rural and urban regions to cover the city’s 441.23 square kilometres. Five geographic models of groundwater depth and type were created using the Inverse Distance Weighting (IDW) interpolation method in ArcGIS software. The results indicate that groundwater is available across the study region, beginning at 100 m and lower depths. Additionally, it has been found that the nature of groundwater fluctuates with the location and depth. The findings of this study aid in selecting wells locations and depths in the study region that generate maximum quality and quantity of groundwater.
