Summary: The study aims to estimate the long-term average seasonal and annual groundwater recharge using the WetSpass model in the Makutupora basin. The findings showed that the wet season had a higher recharge of 24.65 mm/year (99%), while the dry season had a lower recharge of 0.24 mm/year (1%). The annual recharge averaged 24.88 mm/year, contributing a total of 37.3 million cubic meters of groundwater to the basin annually. These results are important for sustainable water management and planning.

Summary: The Valle Alto basin in Bolivia is vital for agriculture and economic development. To ensure sustainable management of water resources, knowledge about groundwater recharge locations and extent is necessary. By using the Schosinsky method, researchers calculated the recharge rate and identified potential groundwater recharge areas in the basin. The study provides important information about the basin's water resources for the first time on a regional level.

Summary: The sustainable use of groundwater resources in arid and semi-arid regions requires accurate understanding of regional water balance components, especially groundwater recharge. This paper presents a method for estimating groundwater recharge by minimizing the total error of system water and groundwater balance equations simultaneously.

Summary: This study assessed the contribution of two adjacent watersheds with low and high urban development to the recharge process of the Memphis aquifer in central Jackson, Tennessee. The results showed that, per unit area, the watershed with low urban development contributed more to recharge and riverbed leakage compared to the watershed with high urban development. However, in terms of total recharge and riverbed leakage, the watershed with high urban development contributed more.

Summary: The study analyzed the temporal and spatial variations of groundwater in the Quaternary aquifer in UAE, revealing a significant decrease in freshwater resources and increase in brackish water. Continuing the current groundwater exploitation could deplete freshwater resources in agricultural areas, necessitating more focus on the management of brackish water resources.

Summary: The understanding of groundwater recharge occurrence in drylands is essential for water resources management. This study used Remote Sensing and GIS techniques to identify potential groundwater recharge zones and predicted crop yield. The results showed changes in land cover and suggested the existence of water resources for food security in water-scarce drylands.

Summary: In semi-arid regions, groundwater resources and recharge potential zones play a crucial role in sustainable development. Through the application of multiple decision-making approaches and GIS technology, this study successfully identified groundwater potential zones, with the southern regions of the Willochra Basin showing greater potential for groundwater recharge. The evaluation of different models showed the frequency ratio model to be the most efficient, followed by the multi-influencing factor model and the analytical hierarchy process technique.

Summary: This study presents a simple water budget model to analyze groundwater depletion in Wadi Zabid, Yemen. The findings indicate that the unsustainable groundwater use in the region is mainly caused by the expansion of agricultural lands. Scenario analysis suggests that reducing agricultural lands and increasing surface water inflow can help reduce groundwater depletion.

Summary: This paper describes a method to constrain the uncertainty in regional groundwater recharge estimates, successfully reducing the uncertainty by nearly a third. The spatial distribution of recharge was primarily influenced by rainfall distribution, but was comparatively reduced in areas with denser vegetation or finer textured soils.

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: This study investigates discrepancies in the modern hydrologic budget of arid catchments in northern Chile, finding that modern water discharge exceeds groundwater recharge. Groundwater flow and drainage of stored groundwater during pluvial periods are needed to balance the water budgets in these regions.

Summary: This study focused on estimating groundwater recharge (GR) in Italy using a water balance method. The results showed variations in GR over time, with exceedances in 1992 and 2015. By comparing GR with anthropogenic water withdrawals, the study also evaluated sustainable water use in Italy. The findings provide new hydrological insights for the region.

Summary: This study examines the effects of land use and land cover (LULC) changes on groundwater recharge in the northwestern part of Bangladesh. The results show that long-term temporal LULC changes have a small impact on recharge at the basin scale, but a larger impact at the regional level due to urbanization. Seasonal LULC variations also affect recharge, with dry LULC having a higher potential compared to wet LULC.

Summary: Research conducted in an experimental catchment in South Australia revealed a paradox in groundwater flow dynamics due to differing groundwater types and recharge rates. During droughts and dry years, high-salinity groundwater contributed a larger proportion of stream flow compared to low-salinity groundwater. This paradox can be explained by the differing drainage rates of the geological formations, leading to varying contributions to stream flow during different hydrological conditions.

Summary: This study utilized satellite products in combination with ground-based data to investigate spatiotemporal variations in water available for groundwater recharge in the mesoscale Thur catchment in Switzerland. The study found that the Thur catchment is in a steady state over the long term, with precipitation being a limiting factor on recharge. The study highlights the value of remotely sensed data in groundwater recharge estimates, while emphasizing the importance of continued ground-based monitoring.

Summary: This study aimed to explore and assess the groundwater quality across the whole area of Hanoi city, as well as identify potential contamination sources. The spatial distributions of major ions and selected elements in groundwater were obtained, showing variations in depth, region, and season. High concentrations of certain elements suggest contamination from the surface.
