Summary: The Heihe River basin depends on both anthropogenic and natural storage, with the Qilian Mountain cryosphere playing a vital role in recharging these supplies. By studying the hydrologic response to cryosphere changes, we found that groundwater can mediate streamflow shifts. Permafrost degradation has a greater impact on the system than glacial loss, and seasonal differences in groundwater-surface-water partitioning are evident.

Summary: In recent years, groundwater modelling has become an important part of projects dealing with groundwater exploitation, protection, and remediation. This study focuses on the groundwater quality along the Noyyal River in Coimbatore city, Tamilnadu. The results show that the center portion of the study area is highly affected and pollutants easily move downstream. Therefore, measures are necessary to control groundwater 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: Climate change effects on groundwater resource developments in Tana Basin, Ethiopia are a growing concern. This study uses a fine-resolution groundwater model to assess the long-term impacts of climate change on groundwater levels and lake releases in the region. The results show significant fluctuations in groundwater levels and predicted changes in lake releases by the end of the century.

Summary: This study proposes a comprehensive evaluation model for predicting trends of ammonia pollution, which shows that the center of the ammonia pollution plume will gradually flow east along with the groundwater over the next 20 years, mainly impacting the groundwater within 200 meters of the river. The model is reliable and can accurately reflect changes in the groundwater flow field.

Summary: Watershed system models are important for understanding complex river basin systems. The study developed a watershed system model for the Heihe River basin in Northwest China, which proved reliable in simulating eco-hydrological processes and exploring interactions between water, ecology, and socioeconomy. This research contributes to a better understanding of the nexus between water, land, air, plants, and humans at the watershed scale and has implications for sustainable development in endorheic river basins.

Summary: The Heihe River basin (HRB), with its unique mountain cryosphere-oasis-desert landscapes and human-nature competition for water resources, has provided an excellent case for the study of critical zones (CZs) and watershed systems. Significant progress and breakthroughs have been made in understanding cryospheric hydrological processes, ecological and hydrological interactions, and surface-groundwater interactions in the HRB. However, challenges remain in observing and modeling geochemical and geomorphological processes in integrated watershed studies.

Summary: The study focused on excessive groundwater withdrawal for irrigation in the Lower Apalachicola-Chattahoochee-Flint River Basin, which has led to declining water levels and reduced baseflows. Evaluating projected impacts, the research found that certain geohydrologic zones were particularly sensitive to recharge. Future irrigation scenarios were simulated, predicting significant reductions in groundwater levels, particularly in areas where the aquifer is thinner. Additionally, analysis of stream-aquifer flux showed substantial reductions, particularly in the Lower Flint and Kinchafoonee watersheds.

Summary: Plastic film mulching is an effective method for managing agricultural fields in water shortage areas, as it can save water and increase crop yield. This study used remote sensing data and modeling to analyze the effects of plastic film mulching on maize yield and evapotranspiration in the Heihe River basin in Northwest China. The results showed that plastic film mulching increased maize yield in certain areas and reduced evapotranspiration in planted areas.

Summary: Preferential flow (PF) is an important process affecting hydrological, geochemical, and ecological cycles. However, the factors that control PF in data-scarce high and cold mountainous areas are not fully understood. This study analyzed the occurrence and spatial-temporal control of PF in a cold, mountainous environment using soil moisture observations in the upper reaches of the Heihe River Basin, Northwest China. The results show that vegetation, soil properties, and water conditions jointly affect the occurrence of PF, and the influence of initial soil moisture on PF varies across different sand content.

Summary: The increased accessibility of groundwater in the alluvial plains of the Kosi river basin has altered the crop calendar and irrigation response of farmers, especially in dry years after 2004. A study developed a framework to analyze the spatio-temporal variation in groundwater recharge/extraction patterns and river-aquifer flux exchange due to increasing anthropogenic activities, finding an increasing trend of river to aquifer flux transfer which may have disturbing long-term effects on river flow and stage.

Summary: This study explores the groundwater mechanisms in the Mekong River Basin (MRB) and finds that groundwater recharge and discharge exhibit high spatial heterogeneity influenced by climate and subsurface characteristics. It is also found that irrigation pumping directly alters groundwater flows and storages, with climate variability smoothing the pumping effects over long times but causing region-wide groundwater depletion (up to 1 m/year) in the Mekong Delta during dry years. This research provides valuable insights into the evolving groundwater systems in the MRB and advances process-based groundwater modeling capabilities.

Summary: This study investigates optimizing the regional cropping distribution in the Heihe River basin in order to improve crop water productivity and reduce irrigation water demand. The results show that maximizing crop water productivity, economic water productivity, and nutrient water productivity can lead to a decrease in the planting area of corn and wheat and an increase in the planting proportion of barley and canola. This reduces irrigation water demand and improves water productivity in the basin.
