&NA; The numerous lakes on the Tibetan Plateau play an important role in the regional hydrological cycle and water resources, but systematic observations of the lake water balance are scarce on the Tibetan Plateau. Here, we present a detailed study on the water cycle of Cona Lake, at the headwaters of the Nujiang‐Salween River, based on 3 years (2011–2013) of observations of &dgr;18O and &dgr;2H, including samples from precipitation, lake water, and outlet surface water. Short‐term atmospheric…

Hydrogen and Oxygen Isotope Composition and Water Quality Evaluation for Different Water Bodies in the Ebinur Lake Watershed, Northwestern China
Wetlands are sensitive indicators of climate change and have a profound impact on the supply of water resources in surrounding areas. In this study, the hydrochemical, isotopic characteristics (δ18O
Variability of Stable Isotope in Lake Water and Its Hydrological Processes Identification in Mt. Yulong Region
Lakes are regarded as important nodes in water resources, playing pivotal roles in the regional hydrological cycle. However, the systematic study on lake water balance is scarce in Mt. Yulong region.
Identifying evaporation fractionation and streamflow components based on stable isotopes in the Kaidu River Basin with mountain–oasis system in north‐west China
Hydrological Processes. 2018;32:2423–2434. Abstract Based on stable isotopes in stream water, groundwater, and meltwater in the Kaidu River Basin, NW China, we estimated the evaporation enrichment of
Estimation of evaporation losses based on stable isotopes of stream water in a mountain watershed
Water stable isotopes (δ2H and δ18O) can record surface water evaporation, which is an important hydrological process for understanding watershed structure and function evolution. However, the
Comparison of isotopic mass balance and instrumental techniques as estimates of basin hydrology in seven connected lakes over 12 years
Mass-balance models using stable isotopes of hydrogen and oxygen provide useful estimates of the water balance of lakes, particularly in the absence of instrumental data. However, isotopic mass
Using stable isotopes to illuminate thermokarst lake hydrology in permafrost regions on the Qinghai-Tibet plateau, China
Thermokarst lakes are widespread and developing on the Qinghai‐Tibet Plateau (QTP), and they have modified hydrological processes and water balance in the region. Despite increasing attention, our


Evaporative enrichment of oxygen-18 and deuterium in lake waters on the Tibetan Plateau
Stable isotopes (δ18O and δD) are useful tracers for investigating hydrologic and climatic variability on a variety of temporal and spatial scales. Since the early isotopic studies on mountainous
Lake Water Isotope Variation Linked with the In-Lake Water Cycle of the Alpine Bangong Co, Arid Western Tibetan Plateau
ABSTRACT Water isotopes play an important role in the study of the alpine lake water budget and the hydrological cycle in the arid, far western Tibetan Plateau. These isotope records, derived from
Estimation of Evaporation from Cona Lake in the Central Tibetan Plateau Using an Isotope-based Method
The isotope-based methods are often used for estimating water balance of a lake.Such isotope-based methods,which primarily rely on water sampling and isotopic analysis,require regional background
Quantifying groundwater dependence of a sub-polar lake cluster in Finland using an isotope mass balance approach
A stable isotope study of 67 kettle lakes and ponds situated on an esker aquifer (90 km 2 ) in northern Finland was carried out to determine the role and extent of groundwater inflow in
Isotopic variation in the lake water balance at the Yamdruk-tso basin, southern Tibetan Plateau
The use of stable isotopes is a practical tool in the study of the lake water budget. This is an one way to study the hydrological cycle in the large numbers of inland lakes on the Tibetan Plateau,
Tracing contributions to hydro‐isotopic differences between two adjacent lakes in the southern Tibetan Plateau
Hydrological processes of lakes in the Tibetan Plateau are an important indicator of climate change. Due to the high elevation, inaccessibility and limited availability of historical observations,
