Summary: The interaction between groundwater and surface water is an important component in sustainable water resource management. The complexity of this interaction increases with scale and is influenced by hydraulic, hydrologic, and hydrogeologic processes. Previous studies have not sufficiently addressed the controlling factors of these processes, and the upscaling of these processes at different scales remains unclear. This review focuses on the controlling factors of the interaction between surface water and groundwater and their upscaling techniques.

Summary: Spatial variability in flow characteristics in discharge zones in five different catchments in Sweden was investigated. Steady-state numerical models and analytical models were used to estimate the deep groundwater flow and hyporheic exchange flow velocities. Regression analysis was performed to explain the variability based on catchment characteristics. The study found that hyporheic exchange flow had a significant potential to accelerate deep groundwater flow velocity and reduce discharge areas.

Summary: Uncertainty in CH4 emissions from inland water, especially rivers and streams, is a challenge due to sparse measurements and measurement uncertainty caused by turbulent water flow. This study developed a process-based model using national hydrography dataset to estimate CH4 flux at the air-water interface. The model showed that sediment hydrologic and biogeochemical conditions estimated from the national hydrography dataset can serve as indicators of CH4 emissions from rivers.

Summary: A multimethod geoelectric survey was conducted to identify locations of surface-water and groundwater exchange and characterize subsurface flow paths in a bedrock-lined stream in Oak Ridge, Tennessee. The survey included a waterborne self-potential (WaSP) survey in the stream and electric resistivity tomography (ERT) on the adjacent flood plain. The combination of WaSP and ERT data supported the interpretation that exchange occurs along fractures and fault lines in the limestone creek bed.

Summary: This study evaluates the changes in groundwater quality in 25 Principal Aquifers in the United States based on decadal sampling from 1988 to 2021. The study finds that concentrations of Na, Cl, dissolved solids, SO4, and NO3 have exhibited statistically significant increases more frequently than other constituents. Factors affecting these trends, such as road-deicing salt application rates and solute concentrations in recharge, are identified. The study also highlights the importance of considering factors such as groundwater residence time and geochemical conditions in interpreting the changes in groundwater quality.

Summary: The interactions between saline seawater and fresh groundwater in subterranean estuaries (STEs) trigger complex hydrological and geochemical processes. These processes are influenced by multiple hydrological factors. Numerical experiments using TOUGHREACT were conducted to study the effects of these factors on groundwater flow and salt transport in STEs. The results show that increasing tidal amplitude, inland freshwater head, seawater diffusion coefficient, and beach slope ratio enhances the exchange of groundwater and surface water, strengthens the density-driven circulation of seawater, and alleviates saltwater intrusion.

Summary: This study examines the spatio-temporal patterns of surface water-groundwater interactions in the Yom and Nan River basins in Thailand under different future climate conditions. The results show that increased air temperature and rainfall can lead to decreased groundwater recharge from surface water percolation, as well as reduced groundwater flow to rivers. However, the impact on aquifer recharge from rivers is minimal. The findings provide valuable insights into how future climate change can affect water supply in northern Thailand.

Summary: This study investigates the natural variability of 222Rn emanation rates in an instrumented alluvial aquifer and highlights the issues with assuming homogeneous 222Rn production in alluvial systems. The measurements reveal that 222Rn emanation rates are highest within the first few meters below the surface. These results have important implications for understanding 222Rn activities in groundwater, particularly in infiltration zones where hydraulic conditions can cause variations in 222Rn signatures.

Summary: This paper introduces a numerical simulator, IC-FERST-REACT, for solving compositional multiphase flow and reactive transport problems. The simulator effectively couples IC-FERST with PHREEQCRM to simulate complex hydrogeological, biological, chemical, and mechanical processes including CO2 geological sequestration. Model coupling is achieved through an efficient API to reduce computational costs and capture flow instabilities. Benchmark examples demonstrate the capability of IC-FERST-REACT in solving multiphase flow and reactive transport.

Summary: By developing three-dimensional heterogeneous models based on field studies and considering the impact of various parameters on CO2 sequestration processes, this research reveals that increasing the volume proportion and connectivity of high-permeability facies enhances both adsorption and dissolution trapping of CO2. Neglecting relative permeability and capillary pressure hysteresis effects may lead to underestimation or overestimation of CO2 trapping capacities.

Summary: Transitioning to renewable energies is crucial for addressing climate change and establishing a sustainable energy system. However, the fluctuation in availability of renewable energy sources poses a challenge of demand and supply imbalance. In this study, we investigate the injection, storage, and production of green hydrogen (H2) in a three-dimensional heterogeneous aquifer system, considering factors such as anisotropy ratio, temperature, relative permeability hysteresis, well perforation placement, and cushion gas type. Our findings suggest that successful H2 recovery depends on the aquifer's anisotropy, temperature, injection and production strategies, as well as the use of low-density and low-viscosity cushion gas.

In this study, researchers proposed a methodology to test and benchmark ML algorithms using artificial data generated by physically-based hydrological models. They found that deep learning algorithms can correctly identify the relationship between streamflow and rainfall in certain conditions, but fail to outperform traditional prediction methods in other scenarios.

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.
