The isotopic composition of precipitation has been measured in samples simultaneously collected during individual events at two neighbouring high-altitude stations (Houxia 2100 m a.s.l. and Gaoshan 3545 a.s.l.) the Tianshan Mts., northwest China. observed changes δ18O (δ2H) deuterium excess with surface air temperature, altitude season have evaluated to derive information on effects subcloud evaporation moisture recycling formation its under arid climatic conditions. Consulting long-term...
Terrestrial moisture recycling by evapotranspiration has recently been recognised as an important source of precipitation that can be characterised its isotopic composition. Up to now, this isotope technique mainly applied in some humid regions, including Brazil, Great Lakes North America and the European Alps. In arid semi-arid contribution transpiration plants local small, so evaporation bare soil surface water bodies dominates. Recognising deuterium excess (d-excess) evaporated is...
This paper synthesizes the research findings on stable isotopes (δ2H and δ18O) of water molecular, with respect to applications in tracing natural cycle. A general purpose diagram δ2H versus δ18O may serve as a geo-indicator various circulation processes is involved: hydrological, hydro-meteorological hydro-geochemical. Equations explanations are provided for total 13 lines that illustrated show fractionation changes when experiencing different processes: GMWL; Moisture recycling line;...
In densely inhabited urban areas, deep borehole heat exchangers (DBHE) have been proposed to be integrated with the pump in order utilize geothermal energy for building heating purposes. this work, a comprehensive numerical model was constructed OpenGeoSys (OGS) software applying dual-continuum approach. The verified against analytical solution, as well by comparing flux distribution. A series of modeling scenarios were designed and simulated study perform DBHE system analysis investigate...
Abstract Deep-borehole heat exchangers (DBHE) are generally coaxial pipes installed in deep boreholes and has become an alternative approach to utilize geothermal energy. Since the performance of DBHE system can be affected by several parameters, it is important optimize design parameters for DBHE. In this paper, based on analytical method, we carried out sensitivity analysis including outer pipe diameter, inner flow rate, materials, grout borehole depth during continuous operation 4 months....
An accurate representation of the spatial distribution stable isotopes in modern precipitation is vital for interpreting hydrological and climatic processes. Considering dominant impact moisture sources controlling water deuterium excess, we conducted a meta-analysis using instrumental data from 68 stations around China. The entire country divided into five regions according to major sources: Region I (the westerlies domain), II arctic III northeast IV Pacific V Tibetan Plateau). Each region...
Abstract Groundwater recharge is poorly understood beneath the glacier due to complex sampling conditions, although it sensitive global change. Here we carried out and isotopic analysis on groundwater, ice‐melt water, river, precipitation through a hydrological year at lowest of Mingyong in Hengduan Mountains, Southeastern Tibetan Plateau. The during monsoon seasons ( P m ) are more depleted heavy isotopes than nonmonsoon nm influence monsoon. water groundwater points both found located left...
