Monitoring of stable water isotopes (18O and 2H) in precipitation and surface waters in the Mackenzie River basin of northern Canada has created new opportunities for researchers to study the complex hydrology and hydroclimatology of this remote region. A number of prior studies have used stable isotope data to investigate aspects of the hydrological regime of the wetland-dominated terrain near...

For more than half a century isotopes have been employed as a powerful tool in studying various aspects of water resources in a largenumber of countries. However, in developing countries like Iran the application of such techniques is in its infancy. The first research inIran was carried out in 1975 to identify the source of saline groundwaters in south Iran, and the first national conference o...

Seasonal oxygen-18 variations in precipitation, throughfall, soil water, spring ̄ow and stream base ̄ow were analysed to compare the hydrology of two forested basins in West Virginia (WV) (34 and 39 ha) and one in Pennsylvania (PA) (1134 ha). Precipitation and throughfall were measured with funnel/bottle samplers, soil water with ceramic-cup suction lysimeters and spring ̄ow/base ̄ows by grab and...

The Arctic’s winter water cycle is rapidly changing, with implications for snow moisture sources and transport processes. Stable isotope values (?18O, ?2H, d-excess) of the Arctic snowpack have potential to provide proxy records these processes, yet it unclear how well individual snowfall events are preserved within profiles. Here, we present data from multiple taiga tundra profiles sampled in ...

A new !O map of southern Nevada groundwater shows a systematic decrease in !O of !5‰ from 36" to 39"N latitude. The variation is consistent with higher-latitude recharge following continuous flow paths along north-south trending graben valleys and systematically increasing in !O due to mixing with lower-latitude, higher-!O recharge. The data do not suggest that large masses of groundwater with ...

Complex networks of both natural and engineered flow paths control the hydrology streams in major cities through spatio-temporal variations connection disconnection diverse water sources. We used spatially extensive temporally intensive sampling stable isotopes to disentangle hydrological sources heavily urbanized Panke catchment (~220 km2) north Berlin, Germany. The isotopic data enabled us pa...
