| Zusammenfassung |
| This study aims at understanding interactions between stream and aquifer in
a glacierized alpine catchment. We specifically focused on a glacier
forefield, for which continuous measurements of stream water electrical
conductivity, discharge and depth to the water table were available over
4 consecutive years. Based on this data set, we developed a two-component
mixing model in which the groundwater component was modelled using measured
groundwater levels. The aquifer actively contributing to streamflow was
assumed to be constituted of two linear storage units. Calibrating the model
against measured total discharge yielded reliable sub-hourly estimates of
discharge and insights into groundwater storage properties. Our conceptual
model suggests that a near-surface aquifer with high hydraulic conductivity
overlies a larger reservoir with longer response time. |
