- Abstract
The article discusses hydrometric and natural tracer (oxygen-18, silica, tritium and sulphur hexafluoride) evidence for a dominant groundwater contribution to the Pukemanga Stream in New Zealand. The contribution is Pukemanga, a steep headwater catchment at the Whatawhata Research Station near Hamilton, New Zealand. Oxygen concentrations from there were measured at weekly intervals for 8-15 months at six sites including Pukemango Stream baseflow through wetland seepage to ephemeral streams and surface runoff. The author explains that silica concentrations may also be used to distinguish deep flowpath water from near-surface flowpath water.
