Investigating Groundwater–Surface Water Interactions and Transformations in a Typical Dry–Hot Valley Through Environmental Isotopes Analysis

Water, Journal Year: 2025, Volume and Issue: 17(6), P. 775 - 775

Published: March 7, 2025

This study investigates the hydrological processes and water body transformation mechanisms in Yuanmou dry–hot valley, focusing on precipitation, well water, spring river reservoir during both wet dry seasons. The spatiotemporal characteristics significance of hydrogen oxygen stable isotopes across these bodies were analyzed. Key findings included following: (i) Seasonal variations shallow groundwater minimal, primarily driven by differences vapor sources transport distances seasonal effects mid-deep influenced leakage recharge from deep aquifers temperature variations, respectively. (ii) line-conditioned excess (lc-excess) deviated significantly Local Meteoric Water Line, indicating that precipitation occurred through slow infiltration piston flow with significant isotopic fractionation. (iii) River was recharged groundwater, water; lateral inflow; groundwater; transfer, strong evaporation effects. (iv) Using a binary isotope mass balance model, ratios to surface calculated be 40% 60%, Additionally, season, proportion increased. provides valuable insights into cycle valleys offers scientific basis for sustainable development management resources arid regions.

Interaction between intermittent river and groundwater in arid and semiarid basin considering the influence of evaporation on isotopic compositions

Journal of Hydrology Regional Studies, Journal Year: 2024, Volume and Issue: 54, P. 101876 - 101876

Published: June 24, 2024

Study region: Tabu Basin is located on a typical-deserted steppe in Inner Mongolia, China and plays significant role maintaining ecological stability of northern China. focus: Among rivers worldwide, 51–60 % cease to flow for at least one day annually, especially arid semiarid areas. Understanding interactions between intermittent (IRs) groundwater (GW) crucial protecting water resources sustaining balance. A comprehensive framework was developed analyze these interactions. New hydrological insights the Unlike previous studies, this study considered seasonal differences hydrochemical isotopic compositions IR GW, as well intensive influence evaporation. Multitemporal datasets were employed IR–GW interaction across spatial, temporal, profiling scales. Hydrochemical evidence analysis indicated input meltwater with depleted signatures GW recharge IR.

Moisture sources and isotopic composition of Meiyu-Baiu rainfall in southwestern Japan from 2004 to 2023

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

To better understand the underlying atmospheric processes responsible for interannual variability of Meiy-Baiu rainfall, we utilized an isotopic regional spectral model to investigate moisture sources and composition Meiyu-Baiu rainfall in southwestern Japan from 2004 2023. Asian Monsoon (AM) moisture, transported by monsoonal southwesterlies middle levels, contributed 50.9% total with low δ²H high d-excess. Conversely, North Pacific subtropical (NPSH) levels accounted 28.6% AM during heavy seasons exhibited lower higher d-excess, due more rainout below-cloud evaporation. In contrast, signals NPSH were relatively consistent between light seasons. Extreme showed d-excess contribution (57.8%) at precipitation efficiency, which facilitates deep convection, triggering extreme events The study highlights importance East Asia. findings providing valuable insights into understanding water cycle Asia, as well improving seasonal forecasts near-future predictions rainfall.
