Article Abstract
Twenty infiltration tests and 12 pumping tests were carried out in Wadi Baysh in southwestern Saudi Arabia. The objective of the study was to assess the soil and aquifer permeability from the point of view of artificial groundwater recharge. Infiltration tests showed that the soil permeability values ranged from 0.58 to 37.15 m/day and showed good recharge potential. The analysis of the pumping tests showed that the aquifer permeability values ranged from 2.6 to 57.4 m/day and were approximately within the same range as those obtained from infiltration tests. Monitoring of groundwater levels in a few wells before and 1 month after a heavy rainfall event in August 2016 shows an average increase of 2.25 m in the groundwater levels which substantiates the recharge rates obtained from infiltration and pumping tests. Average annual groundwater recharge for the area calculated from water table fluctuation method is 72.08 mm/year indicating that the lower reaches of Wadi Baysh catchment has good potential for groundwater recharge and if managed properly can help in tackling the problem of groundwater depletion due to excessive pumping.

Large and complex karst catchments, like the one in Southern Dalmatia (Croatia) and Western Herzegovina (Bosnia and Herzegovina), are fragile environments requiring careful protection and sustainable water resources management. Understanding the processes that influence karst aquifer water chemistry is essential for the effective protection of water quality and quantity, ensuring sustainable resource availability and minimizing vulnerability to contamination. A hydrogeochemical dataset comprising over 30 groundwater (springs) and surface water samples, was collected in this cross-border catchment area from September 2013 to September 2020, accounting for seasonal variations.

Our recent steady-state mass-balance modeling suggests that most global carbonic-acid weathering of silicate rocks occurs in the vadose zone of aquifer systems not on the surface by atmospheric CO. That is, the weathering solute flux is nearly equal to the total global continental riverine carbon flux, signifying little atmospheric weathering by carbonic acid. This finding challenges previous carbon models that utilize silicate weathering as a control of atmospheric CO levels.

The Abijata-Langano-Ziway Lakes Basin (ALZLB) is situated in the Central part of the Main Ethiopian Rift. The availability and dynamics of groundwater in the Abijata-Langano-Ziway Lakes Basin (ALZLB) are primarily controlled by its geological and hydrogeological characteristics, shaped by volcanic-tectonic and sedimentary processes. The basin faces significant challenges, including drastic change in land use pattern, rapid population growth sustained by subsistence farming, over-extraction of water resources, and vulnerability to climate change and fragile ecosystems.

Agricultural intensification in the Northwestern Indo-Gangetic Plain (NWIGP), a critical food bowl supporting millions of people, is leading to groundwater depletion and soil health degradation. This is primarily driven by conventional cultivation practices in the rice-wheat (RW) cropping system, which dominates over 85% of the IGP. Therefore, this study presents a systematic literature review of input management in the RW system, analyzes district-wise trends, outlines the current status, identifies problems, and proposes sustainable management options to achieve development goals.

This study assessed the chemical composition of major elements and stable isotopes (H and O) in precipitation, groundwater, and surface water in São Francisco 1 (SF1) sub-basin (approximately 14,000 km), located at the São Francisco River headwater region, fractured aquifer system region with a complex geologic framework. Both groundwater and surface water exhibited low mineral content, with average electrical conductivity of 147.2 ± 99.
