Copper Creek Baseflow Age Experiment using Environmental Gas Tracers in the East River Watershed, CO.
Description
Groundwater contributions to streams, or baseflow, represents a mix of numerous flow paths through the subsurface of varying ages that are important to understanding system hydrologic lag and solute export. To better constrain numerical estimates of baseflow age, we used a novel experiment from Sanford et al. (2015) based on stream water concentrations of environmental gases (SF6, N2 and Ar) and an assumed Weibull distribution for a Colorado (CO) River headwater basin, Copper Creek (24 km2). The data package contains steam data collected over a 12-hour period on August 27, 2017 and the finite difference approximation for the mass balance approach.
