Summary: Groundwater flow modeling in a small-scale area requires practical techniques to obtain high accuracy results. In this study, an optimized groundwater flow calibration method based on the pilot point emplacement technique was proposed for a 3D small-scale area. The effectiveness of different emplacement structures and densities for the pilot points were tested, and the calibration accuracy was found to depend on the frequency and emplacement of the pilot points.

Summary: Winter deicers contribute to chloride contamination in shallow aquifers in northern latitudes. In the greater Chicago area, chloride has been accumulating for decades, exceeding the EPA standard in many places. Simulations using MODFLOW-NWT and MT3D-USGS show that chloride accumulation in the Will County aquifer is affected by geologic features and point sources, and reducing deicing rates is crucial to prevent further contamination.

Summary: The Chiang Mai basin is facing a critical groundwater condition with a continuous decrease in water table and potentiometric surface, indicating the need for careful management. The spatial variability of hydrogeologic parameters significantly affects the accuracy of the groundwater flow model, with hydraulic conductivities and recharge rates being the most sensitive parameters. The safe yield calculation suggests that the unconsolidated aquifers of the Chiang Mai basin can sustain higher extraction rates than the current levels.

Summary: A better understanding of seawater intrusion in coastal aquifers is crucial for groundwater resource management. This study investigated the dynamics of saline water under different hydraulic gradients and managed aquifer recharge (MAR) through sand tank experiments and numerical simulations. The results showed that the retreat rate of the saline water interface is higher than the intrusion rate, and MAR in highly conductive aquifers is less effective in combating seawater intrusion.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.
