Summary: This study focused on the trends of groundwater level changes in the Sylhet region of Bangladesh by using geostatistical methods to analyze the annual-average depth to the water table at 46 observation wells. The results showed a substantial increase in groundwater depths in some locations from 2000 to 2015, identifying vulnerable zones in the area due to lowering groundwater trend. This research contributes to groundwater management in developing countries by providing insights into spatial and temporal groundwater variation.

Summary: In this paper, the SWAT-MODFLOW-Salt model is introduced, which simulates the fate and transport of major salt ions in watershed systems, with a focus on irrigated stream-aquifer systems. The model accounts for water and salt mass storage and movement in different components, and was applied to a managed region in Colorado to study the impact of soil salinity on crop yield.

Summary: This study evaluates the cause of salinization in an irrigation scheme in the Tigray region of northern Ethiopia, finding that salinity and toxicity hazards increase with the direction of water flow. The main control mechanisms of groundwater chemistry include the dissolution of carbonate minerals, silicate weathering, and cation exchange. The impacts of dam construction on the hydrologic environment, such as enhanced groundwater potential, were also discussed.

Summary: The quality of groundwater in the Jaunpur district of Uttar Pradesh, which is the only source of water for drinking and irrigation, has been poorly studied. This study evaluated the groundwater's suitability for drinking and irrigation using various chemical parameters. The findings revealed that most of the groundwater samples had high levels of EC, TDS, and TH, indicating unsuitability for drinking and irrigation. The study suggests that the groundwater in the area should be treated before drinking. However, it is suitable for irrigation.

Summary: Groundwater plays a vital role in drought mitigation, but lack of monitoring data makes it challenging to forecast future levels accurately. This study proposes a novel and simple method using geostatistics, optimal exogenous variables, and artificial neural networks for short-term groundwater level forecasting. Analysis shows that wells closer to the central part of the aquifer have stronger correlations with precipitation. Among the approaches with exogenous variables, NARX and Elman models using effective precipitation were found to be the best in most cases. The accuracy of the forecasting results varies depending on the well, with an average RMSE of 1.14 m for the selected approaches.

Summary: High salt loading from watersheds into rivers can negatively affect downstream water quality and crop production. This study investigates salt movement and loadings in a high-desert catchment using a watershed model and finds that most of the salt originates from subsurface water pathways. Additionally, it predicts that increased storm intensity will lead to higher salt loads, highlighting the need for comprehensive salt management strategies in desert regions.

Summary: Salinity and sodicity have been significant environmental hazards over the past century, affecting over a quarter of the world's land and causing adverse effects on agriculture and ecosystems. Despite various remediation techniques, comprehensive land reclamation remains challenging, with growing salt-resistant crops and improving drainage being the most practical solutions to mitigate the risks of salinity and sodicity.

Summary: Brunei has made significant progress in agricultural development, but crop production, especially rice, is still insufficient due to water scarcity, acidic soils, and environmental deterioration. This study investigated the soil and groundwater conditions at three rice cultivation sites in Brunei. The results showed potential aquifer zones and shallower groundwater levels in irrigated sites. The groundwater and soil properties indicated high alkalinity, mineralization, and salt ion leaching. Future irrigation activities should consider local aquifer characteristics, groundwater flow paths, and nutrient transport to ensure sustainable development in agricultural areas.
