Summary: This study introduces a new concept that combines the index-overlay method with a physical-based numerical model to predict groundwater sustainability. Results show that considering different climate conditions in the numerical model can improve the accuracy of groundwater vulnerability prediction, with future climate conditions having a relatively small impact on groundwater vulnerability in the Pingtung plain groundwater basin. The groundwater resource system in this area is found to be in a critical state of high vulnerability based on sustainability indicators analysis.

Summary: This study proposes an evaluation method combining aquifer intrinsic vulnerability and pollution source loading to assess groundwater contamination risk in Guanzhong Basin. The results indicate that industries and landfills are the most harmful potential pollution sources, with high vulnerability areas mainly located around Huazhou District, Huayin and Dali County. The areas of high groundwater contamination risks are Xi'an City, Xianyang City, Hancheng City, and Dali County.

Summary: The study introduces two new indices to evaluate aquifer sustainability, focusing on assessing groundwater restoration strategies' impacts on the aquifer's qualitative and quantitative sustainability. By using MODFLOW simulations and Bayesian networks models, the indices provide valuable insights into achieving sustainable management in groundwater restoration scenarios through reduction in groundwater withdrawal and other strategies.

Summary: Karst in China is widely distributed and has diverse forms, making it a representative example worldwide. The unique hydrogeological features of semiarid karst areas in northern China, such as covered karst and weak development, pose challenges in assessing the vulnerability of karst groundwater using the COP method. This study developed an improved COPK method and applied it to the Baotu Spring basin, demonstrating its efficiency in vulnerability assessment of covered karst areas in northern China.

Summary: This study examines the groundwater vulnerability of the chalk aquifer in northern France using the DRASTIC method, finding that areas with lower groundwater depth and higher permeability have higher vulnerability. Land use has little effect on the distribution of vulnerability classes.

Summary: This study used peanuts as an example to explore vulnerability to agricultural drought in China. A multi-source data fusion drought index (MFDI) was constructed and analyzed to show variations in drought severity during different growth periods of peanuts in Shandong Province. The three-dimensional vulnerability assessment method established in this study provides a new approach for agricultural drought vulnerability assessment and supports local governments in formulating disaster prevention and mitigation policies.

Summary: This study modified the DRASTIC method by incorporating land use and water quality index to assess groundwater vulnerability in the Halabja-Khurmal sub-basin in NE/Iraq. The results showed that 1.3% of the total area had very high vulnerability and 46.1% had high vulnerability. The modified DRASTIC index demonstrated a strong correlation with nitrate concentration.

Summary: The RIVA method was successfully applied for assessing groundwater vulnerability, showing a wide spatial distribution of vulnerability levels and over 80% match between modelled and monitored values. Some deviations were observed in areas affected by lateral crossflows and contamination, but RIVA proved to be an accurate and data-intensive tool.

Summary: This study evaluated the vulnerability of shallow karst groundwater in Hebi City in northern China using different models, finding that the improved COPK model was the most suitable. The study also assessed the groundwater pollution load intensity and divided the study area into different classes based on the relationship between groundwater pollution load intensity and quality.

Summary: This study proposes a hybrid evaluation approach to determine groundwater quality indices (GQIs) for irrigation, seawater intrusion, and potability. The approach combines water quality indicators, hydrogeological factors, and socio-economic factors to assess groundwater suitability. The results highlight the importance of factors such as recharge, distance from coastline, and rivers in determining groundwater quality. Spatial modeling using machine learning algorithms is used to predict GQIs for different indices. The developed map and approach can serve as a practical guide for groundwater management and identifying suitable areas for various uses.

Summary: The study investigated the groundwater quality changes in Zrebar lake basin in Iran from 1992 to 2018, revealing a significant decrease in forest area and an increase in agricultural and human-made construction areas. Despite a decrease in rainfall and changes in land use, the quality of water remained suitable for drinking and agricultural consumption.

Summary: Developing a predictive decision model for assessing vulnerability of hidden groundwater reservoir formation to contamination risk is crucial for managing global water resources security crisis. This study utilized multiple methodologies including GIS, AHP-based data mining, and statistical and geophysical techniques to develop a novel GODL vulnerability method. The validation results showed that the GODL model performed better than the GOD model, demonstrating 70% prediction accuracy compared to 66% for the GOD model.

Summary: The study utilized the DRASTIC model to estimate aquifer vulnerability in areas vulnerable to anthropogenic pollution. The results categorized the research area into high, medium, low, and very low drastic index values, with the SW and NE areas identified as the most vulnerable zones. Additionally, VES and EC results showed a freshwater aquifer in the NE area, brackish water in the SE area, and brackish water in the rest of the area. Validation conducted for the DRASTIC and EC models showed a positive correlation, highlighting the need for wastewater treatment policies to prevent groundwater contamination.
