Evapotranspiration from Wetland and Open-Water Sites at Upper Klamath Lake, Oregon, 2008–2010


Table 9. Results of modeling biweekly evapotranspiration (ET) during the study period (n = 63) at both sites using the ensemble-mean Kc approach during the growing season and the mean Kc approach during the non-growing season.


[Slope and intercept are of ordinary least squares best-fit line between modeled and measured ET. Abbreviations: CE, coefficient of efficiency; -, mean ET during the study period; mea, measured; mod, modeled; mm d-1, millimeters per day; r 2, coefficient of determination; RMSE, root-mean-square-error]
