Table 5. Goodness-of-fit velocity statistics for the UnTRIM model of Upper Klamath Lake, Oregon, 2006.

[Errors are calculated half-hourly as observed value-simulated value. A spatially variable wind was used in the simulation. Full Season at ADCP1a is from May 24 to July 18 when the instrument was moved to a new position; full season at ADCP1b is from July 19 through September 25 at the new position; full season at ADCP9 is May 24 to September 25. Mid-summer is from July 26 to August 31. Site modifier: -u indicates east/west component of velocity; -v indicates north/south component of velocity; (b) indicates 1 meter from bottom, (s) indicates 1 m from surface. Abbreviations: cm/s, centimeter per second; –, no data]
