Summary:Based on a GIS platform, the vulnerability of shallow Quaternary groundwater of the Hanjiang River valley plain in Zhongxiang City, Central Hubei Province, was evaluated using the GOD model using three assessment indices: groundwater type, lithology of cap rocks, and groundwater depth. The results indicate that the vulnerability scores of shallow Quaternary groundwater are between 0 and 0.7. Based on the results, the evaluated area is divided into different sub-areas: very low vulnerability areas (score: 0-0.1), low vulnerability areas (score: 0.1-0.3), medium vulnerability areas (score: 0.3-0.5), high vulnerability areas (score: 0.5-0.7), and very high vulnerability areas (score: 0.7-1.0), with a proportion of 0.3%, 0.0%, 64.1%, 35.6% and 0.0% respectively. It is found that the shallow Quaternary groundwater in most evaluated areas has medium or high vulnerability and the areas with high groundwater vulnerability are almost all distributed along the Hanjiang River. Thus, it is necessary to strengthen the prevention and remediation of groundwater pollution to solve the contradiction between the strong pollution potential and highly vulnerable groundwater environment found in Zhongxiang City.
