E. Kumar et al.

Summary: This study focused on quantifying primordial radionuclides in soil samples collected from mining and non-mining regions of Ariyalur taluk, Tamil Nadu, South India. The radiological parameters were assessed, and it was found that certain samples in mining areas had higher activity concentrations compared to the global average value. Spatial distribution and geo-statistical analysis were performed, and regression analysis was conducted to correlate health and ecological risk parameters with the primordial radionuclides.

Isotopic Assessment of Groundwater Salinity: A Case Study of the Southwest (SW) Region of Punjab, India

Gopal Krishan et al.

Summary: Due to rapid increases in water demand and irrigation, waterlogging issues have developed in the southwest zone of Punjab, along with a stagnation in saline zone formation due to salinity ingression. This study conducted research in three districts of Punjab, collecting and analyzing groundwater samples to understand the causes of salinity. The results showed that salinity in groundwater is a result of evaporation enrichment and salt dissolution. The study also identified the zone of interaction between aquifers.

Hydrochemical characteristics and D-O-Sr isotopes of groundwater and surface water in the northern Longzi county of southern Tibet (southwestern China)

Xiao Yu et al.

Summary: This study analyzed the water resources in the southern Tibet using various methods, and found that the major ions in the water were SO24-, HCO3-, and Ca2+. The types of groundwater and surface water were mainly Ca-HCO3 and Ca-SO4. The dissolution of gypsum, calcite, and dolomite was identified as the main factor affecting water quality. D-O isotopes and Sr-87/Sr-86 ratios revealed the recharge source of the water and the main minerals interacting with water.

Stable isotopes of surface water and groundwater in a typical subtropical basin in south-central China: Insights into the young water fraction and its seasonal origin

Xiong Xiao et al.

Summary: This study found that precipitation input affects the stable isotope variations of river water, creek water, and shallow groundwater in the Xiangjiang River basin, but this effect is attenuated during runoff confluence processes. The renewal cycle of water sources in river water and shallow groundwater is faster than in creek water, which is influenced by adjacent mountains. Winter precipitation plays a more significant role in supplying river water and creek water, while shallow groundwater is supplied by a mixture of precipitation in different seasons. This highlights the importance of vegetation and soil conservation in maintaining inter-seasonal water storage and the need to assess the risks of streamflow contamination.

Surface water isoscapes (δ18O and δ2H) reveal dual effects of damming and drought on the Yangtze River water cycles

Huawu Wu et al.

Summary: The water regimes and biogeochemical cycles are significantly affected by river damming and drought. This study investigated the altered water cycle associated with damming and drought along the Yangtze River. The results showed that river water isotopes varied spatially and temporally, with increased evaporative fractionation under abnormal drought conditions. The changes in water cycle are important for water resource management.

Revealing the impact of water conservancy projects and urbanization on hydrological cycle based on the distribution of hydrogen and oxygen isotopes in water

Chengcheng Xia et al.

Summary: The study used stable isotopes to analyze the impact of water projects and urbanization on the hydrological cycle, finding significant changes in natural hydrological processes due to urbanization and water projects. Isotopes were found to be closely related to river water level changes and showed distinct differences in rainfall-runoff responses in different areas. Stable isotopes are sensitive to land use changes and runoff generation, providing valuable insights for water resource and environmental risk assessment.

Impact of landscape dams on river water cycle in urban and peri-urban areas in the Shiyang River Basin: Evidence obtained from hydrogen and oxygen isotopes

Guofeng Zhu et al.

Summary: This study analyzed the isotopic characteristics of water samples collected from urban and pen-urban areas in the arid region of Central Asia to evaluate the hydrologic effects of landscape dams. The results showed that landscape water had higher isotopic values than natural river water and the evaporation loss ratio was increased by 0-5%. Additionally, the cumulative effect of multiple landscape dams led to significant water resource loss in arid regions, highlighting the need to consider potential adverse effects in long-term water-resource sustainability planning.

Using StorAge Selection (SAS) functions to understand flow paths and age distributions in contrasting karst groundwater systems

Zhicai Zhang et al.

Summary: The study found that the flux age distribution of the three karst groundwater systems exhibit similar seasonal variations, indicating a strong hydrological connection between hillslopes and depressions at seasonal scales. The age distribution of outflow shows a high-low-high variation pattern in the whole catchment and a high-low-low pattern in the hillslope system at the beginning of the wet season. The distribution of soil and epikarst related to the system storage capacity, in addition to sinkholes in the depression, likely controls the variations of flow paths under different wetness conditions and influences the age distributions in runoff for different karst systems.

Isotopic temporal and spatial variations of tropical rivers in Thailand reflect monsoon precipitation signals

Jeerapong Laonamsai et al.

Summary: Stable isotopic compositions of 25 rivers in Thailand were analyzed monthly from 2013 to 2015. The study found that monsoon precipitation significantly influences river isotopes, leading to spatial and temporal variations in isotopic compositions among different geographical regions. This research can be used to explore hydrological interactions in other tropical river basins.

Isotopes (618O,6D and 3H) variations in groundwater with emphasis on salinization in the state of Punjab, India

Gopal Krishan et al.

Summary: Punjab's agrarian economy is facing challenges due to falling groundwater levels and deteriorating groundwater quality, with increasing salinity being a major concern. Irrigation needs are met by groundwater and canal water, but canal irrigation has led to waterlogging and subsequent salinization, rendering fertile land unproductive in the south-western part of Punjab. Further research is being done to understand the dynamics of groundwater recharge and the effects of evaporation on salinity levels.
