Fig. 13. Observed (obs) and simulated (sim) temperatures in the Merced River, CA, streambed for (A) a single hydraulic conductivity (K) value of 1.2 x 10^–5 m s^–1 and (B) a K value of 1.2 x 10^–5 m s^–1 for the first part of the simulation and an increased K value of 1.210^–4 m s^–1 after the October 2004 high-flow event.
