摘要: Temperature is routinely collected as a water quality parameter, but only recently utilized an environmental tracer of stream exchanges with ground (Stonestrom and Constantz, 2003). In this paper, levels seasonal temperatures were used to estimate streambed hydraulic conductivities fluxes. Temperatures analyzed from 3 observation wells near the Russian River RBF facility, north Forestville, Sonoma County, CA. addition, 9 shallow piezometers installed in cross-sections across pair collector at facility. Hydraulic fluxes estimated by matching simulated ground-water observed inverse modeling approach. Using temperature measurements 0.1 1.0 m below channel, estimates infiltration indicated distinct area clogging one wells. For deeper wells, probes located depths between 3.5 7.1 channel. Estimated varied over order magnitude, anisotropies 5 (horizontal vertical conductivity) generally providing best fit temperatures.
