Abstract |
Three numerical models have been adapted to predict temperatures in the main stem Columbia River, extending 750 miles from the Canadian border to the mouth of the river at Astoria, Oregon. These three models facilitate prediction of temperatures in the four hydraulic regimes which comprise the main stem Columbia in the United States. The models are: The weakly stratified reservoir model; the river-run reservoir model; and the estuary model. The computer software (programming) for the weakly-stratified reservoir model and the river-run reservoir model, as well as the necessary hydraulic, hydrologic, and meteorologic data, constitutes the Columbia River temperature model. |
