英文摘要	Study Region This study considers river water and groundwater in seeps and springs collected from the non-monsoon season in the valleys of the Dudh Koshi River in eastern Nepal and the Niyang River of eastern Tibet, both in the Himalaya Mountains. Study Focus Data from this study comprise water samples that provide a single season snapshot of delta O-18 and delta D values that give additional information into the sources of moisture and the altitude lapse rates for the southern flank of the High Himalaya of Nepal and the Eastern Nyainqentanghla Mountains of the Tibetan Plateau. New Hydrological Insights The local water line for Nepal samples, delta D = (7.8 +/- 0.3) . delta O-18 + (4.0 parts per thousand +/- 4.6 parts per thousand), was moderately lower in slope than for Tibetan Plateau samples, delta D = (8.7 +/- 0.1) . delta O-18 + (24.3 parts per thousand +/- 2.0 parts per thousand); evaporation has a greater influence on the Nepal samples-consistent with warmer temperatures in Nepal versus Tibet within the same altitude range. Mean d-excess values for Tibet samples (13.1 parts per thousand +/- 2.0 parts per thousand) implies that recycled continental moisture has more influence than marine moisture observed for the Nepal samples (7.4 parts per thousand +/- 4.4 parts per thousand). Altitude lapse rates of delta O-18 and delta D for Nepal samples (-2.8 parts per thousand km(-1) and -24.0 parts per thousand km(-1)) do not significantly differ from Tibet samples (-3.1 parts per thousand parts per thousand km(-1) and -27.0 parts per thousand km(-1)) and regional measurements; the lapse rates are reduced above 4500 m and are not influenced by exceptionally high elevations in the Dudh Koshi River watershed.
