Isotope Input into Runoff Systems from Melting Snow Covers
Isotope Input Runoff Systems Melting Snow Covers
2009/10/28
Stable environmental isotope techniques contribute to reasonable separations
of the direct runoff component in snowmelt hydrographs. For the separation
procedure, the actual isotope input from snow ...

2009/5/18
δ18O measurements in precipitation and stream waters were used to investigate hydrological flow paths and residence times at nested spatial scales in the mesoscale (233 km2) River Feugh catchment in t...
Isotope hydrology of dripwaters in a Scottish cave and implications for stalagmite palaeoclimate research
Isotope hydrology stalagmite palaeoclimate research Scottish cave
2009/5/4
Dripwater hydrology and hydrogeochemistry is particularly useful in constraining the meaning of speleothem palaeoclimate archives, for example using δ18O signatures. Here, we calibrate the relationshi...
