Summary: It has been found that stable water isotopes can indicate the sources of groundwater recharge. The composition of d18O and d2H reflects the mixture of water at the surface and the origin of moisture during precipitation and infiltration. Therefore, understanding the spatial variability in groundwater recharge and flow paths is crucial for effective aquifer management. This study uses stable water isotopes (d18O and d2H) and groundwater level measurements to investigate groundwater recharge sources and flow paths in the Bilate River watershed, Ethiopia. The isotopic ranges in groundwater samples are more similar to precipitation than river water. The analysis shows that local rainfall is the dominant recharge source for the groundwater. However, there is high enrichment of groundwater isotopes in the northeast and east of the watershed, indicating a mixture of groundwater and surface water due to lake water intrusion.

Summary: Through investigating the Goodwater Creek Experimental Watershed in Missouri, we found that soils with low permeability are prone to nutrient loss and determining hydrologic pathways is crucial for stream contamination mitigation. The complex recharge pathways create stochastic conduits for nitrate transport, posing significant challenges for water quality management.

Summary: In this study, we estimate the changes in subsurface water in California using various data sources. The results show that a portion of precipitation infiltrates the subsurface but is later lost through evapotranspiration and lateral subsurface flow, with the majority of losses occurring in the southern region of the Central Valley. Additionally, the groundwater levels in the Central Valley fluctuate significantly on an annual basis. It is worth noting that a portion of the groundwater lost during recent severe droughts has been replenished during subsequent years of heavy rainfall.

Summary: Groundwater in Ethiopia is threatened by rapid urbanization and industrial expansion, with recharge mostly occurring from July to October. SWAT model was used for recharge estimation, while MODFLOW 2005 was utilized for groundwater flow system numerical simulations, revealing areas of interactions between the river and groundwater. The study suggests that increasing pumping rates or reducing recharge poses significant risks to groundwater sustainability in the area.

Summary: Understanding the timing, location, and rates of recharge is essential for groundwater management and ecosystem sustainability. This study investigated the spatiotemporal distributions of recharge events in a large watershed in the Great Lakes region, examining the impacts of various factors on simulated recharge. The results showed that recharge dynamics are influenced by climate variations, land cover types, and soil types, with high recharge values associated with high elevations and regions of low evapotranspiration.

Summary: Mountain block recharge is an important component of the water budget for alluvial aquifers, but understanding and quantifying its dynamics is challenging. This study investigates two alluvial aquifers in Haiti and finds that river infiltration from the mountain block is a major source of recharge. The study also highlights the significance of the Massif de la Selle carbonate aquifer system, which has a much larger recharge than the alluvial aquifers and supplies a significant portion of the water to the metropolitan area of Port-au-Prince.

Summary: This paper reviews the aquifers and groundwater resources in the Densu River Basin in Ghana, West Africa. It highlights the hydrogeological and hydrochemical characteristics, water quality and quantity challenges, and the potential impacts of climate change and human activities on the groundwater resources. The study reveals that groundwater recharge exceeds abstraction in the basin, but it is at risk due to climate change threats and population growth. The quality of the groundwater is generally acceptable, but contamination from domestic waste discharge, mining, and agriculture is significant. The paper emphasizes the need for integrated hydrogeological assessment to enhance understanding of aquifers and groundwater resources for informed water management decisions.

Summary: Cities in arid and semiarid regions face the challenges of managing floods and water shortages. A study in Kabul, Afghanistan investigates the potential of rainwater harvesting (RWH) to address these issues. The analysis shows that implementing RWH systems can increase infiltration and recharge groundwater, making it an effective strategy for flood management and artificial recharge.

Summary: Aquifer recharge is crucial for understanding groundwater volumes and sustainable use of natural water resources. This study evaluated various methods to determine recharge in a flood basalt terrain, revealing the influence of snowmelt on recharge. By combining groundwater modeling and hydrologic tracers, the appropriate recharge values were determined for different terrains.

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: Estimating the spatial and temporal patterns of groundwater recharge through integrated water balance modeling is essential for sustainable groundwater resource management. A water balance model (WetSpass) was used to estimate groundwater recharge in the data-scarce Rift Valley Lake basin. The model showed good performance in simulating groundwater recharge in the Upper Gelana watershed.

Summary: Conventional tillage practices worsen global environmental changes and impact food production sustainability. No-till agriculture has been introduced as a conservation practice to combat these challenges. Integrated long-term field data and modeling show that no-till practices can significantly increase soil moisture, net return, and groundwater recharge at the watershed scale.

Summary: This study presents a systematic approach to identify the origin of alkane gases in groundwater, using isotopic tracers and considering four potential processes affecting the gas composition. Results from a study area in southern New Brunswick demonstrate that methane and ethane in groundwater from the McCully gas field are of microbial origin, while thermogenic gases were detected in the Elgin area affected by mixing, oxidation, and late-stage methanogenesis. The approach used in this study successfully distinguishes the original isotopic signature from post-genetic modifications and shows no evidence of hydraulic fracturing impacting shallow groundwater quality.
