Martis Valley Surface Water/Groundwater Interaction Study

InterFlow Hydrology completed a survey of spring and stream discharge throughout Martis Valley, and provided analyses of streamflow to account for stream gains from groundwater discharge. The study improved the understanding of surface and groundwater interactions within Martis Valley, and corrected previous estimates of stream gains in the local water budget. In addition to numerous discharge measurments and review of gage records, the project also incorporated channel geometry measurements via the Hedman-Osterkamp method for estimating perennial flow in ungaged streams, and aqueous chemistry to evaluate mixing of groundwater with surface water.
