| Zusammenfassung |
| This paper considers the potential of oxygen and hydrogen isotope ratios to identify spatial and temporal changes in
the water source of a lowland headwater wetland situated adjacent to the River Tern in Shropshire, UK. Stable isotope composition (d18O)
of end-members varied between –7.5 and –8.0‰ for groundwater, –7.3 and –8.5‰ for river-water and –4.5 and –8.0‰ for precipitation. Water
samples were extracted from six nests each comprising three porous cup samplers at depths of 0.2 m, 0.5 m and 1.0 m between June 2000 and
October 2001, and their isotope compositions determined. Groundwater appears to be the main source of water to the wetland, but stable
isotope ratios enable seasonal variations in the contribution of precipitation to be determined, and indicate the extent of precipitation
storage within the wetland.
