The thermal energy conservation equation in the form of a quasilinear partial differential equation, having been previously validated on the Columbia River, is here calibrated on a 5-mile reach of the Little Deschutes River for a 9-day period (July 29 - August 6, 1969) treated as three 3-day episodes. With 3-hr unit hydrodynamic-meteorologic data, the water temperature prediction capability of this dynamic deterministic one-dimensional model is on the average within 0.4DF. Signally, this accuracy was accomplished under both parametric and nonparametric statistical validity tests which indicate a certain level of acceptance; and, drought conditions in the form of fractionally reproduced flow caused this mathematical model to respond as expected.
