A new method for identifying groundwater contributions to stream baseflow
Understanding the contribution of groundwater to river flow is critical for the sustainable management of water resources and environmental flows. The results of this study will provide water managers with a new and innovative set of validated techniques that will supersede current ad hoc baseflow analysis techniques. This study will use innovative time-series analysis techniques of existing streamflow and groundwater head data to determine the contribution of groundwater to baseflow and the new techniques will be evaluated using hydrochemical field sampling.
