Summary: This paper investigates the groundwater recharge sources and processes in Bist-Doab, Punjab, northwest India, using water isotopes and specific electrical conductivity (SEC). The study reveals that meteoric sources from high intensity events dominate groundwater recharge, but there are also significant surface water inputs in some sites near canals and rivers. Rapid changes in groundwater recharge sources are observed, particularly related to post-monsoon pumping and seasonal connectivity to surface water inputs. The study also highlights the risk to groundwater sources from surface water ingress and the potential concern of high salinity changes in shallow groundwater with relatively low SEC.

Summary: Groundwater exploitation reduction and cross-regional water diversion projects have significant impacts on the water cycle in the North China Plain. This study characterized groundwater recharge sources using stable isotopes, geochemistry, and water levels in a major agricultural production base. The research found that surface water and semi-confined groundwater were the main recharge sources for the unconfined groundwater, with preferential recharge during heavy rain events. The confined groundwater mainly consisted of old water and had weak hydraulic connections with the upper aquifers. These findings provide important insights for aquifer restoration and integrated water resources management.

Summary: In Pakistan, a water-scarce country, rainfall is an important source of freshwater, but it is often mixed with sewage in urban areas, making it unsuitable for managed aquifer recharge. This study examines the potential of using rainfall for managed aquifer recharge in Lahore, Pakistan. Samples of rainwater were collected from three different sites in urban and rural areas, and their quality in terms of various parameters was analyzed. The study finds that directly captured rainwater is the most suitable option for managed aquifer recharge, followed by rooftop runoff.

Summary: The relationship between groundwater and seawater is sensitive, especially in coastal regions with developed faults. In this study, the impact of groundwater exploitation on confined groundwater and seawater was analyzed in the Subei Basin. The results show that seawater intrusion has negligible effect on confined groundwater, but groundwater desalination is apparent. The study also reveals that the upward recharge of basalt groundwater through active faults plays a significant role in the relationship between groundwater and seawater.

Summary: The present study aims to delineate groundwater zones in the Bist-Doab region of Punjab, India using multi-criteria decision analysis based on land-use/cover pattern, groundwater table, and groundwater quality for domestic and agricultural use. The study reveals that about 71% of the region is used for agriculture, 12% for built-up areas, 7% for forest cover, 5% for tree plantation, 3% for water bodies, and the remaining 2% for open areas. Additionally, the groundwater table shows that around 8% of the region has a groundwater table below 30 m, mainly concentrated around urban areas. Qualitatively, the study finds that certain areas have unsuitable groundwater for domestic consumption and irrigation, with poor water quality mainly observed in urban agglomerations due to high urbanization and industrialization.

Summary: This study estimates the active surface deformation, displacement pattern, and erosional variability using the geomorphologically sensitive morphometry and the PSInSAR technique. The results show that the Raunthi River catchment is undergoing subsidence and uplift, leading to high erosion in the Raunthi River sub-basin. The study refutes the notion that temperature rise was the major trigger for the recent disaster, but suggests that sheared lithology and preexisting fissures played a key role. It calls for detailed investigation in glacial and paraglacial regions of the Himalayas.
