Note générale :	A coupled flow temperature model is developed and verified for a 27.9 km reach of the Chattahoochee river between Buford dam and Norcross, Ga. Flow in this reach of the Chattahoochee is continuous but highly regulated by Buford dam, a flood-control and hydroelectric facility located near Buford Ga calibration and verification utilized two sets of data collected under highly unsteady discharge conditions. Existing solutions techniques, with certain minor improvements are applied to verify the existing technology of flow and transport modeling. The temperature model is capable of predicting temperature change through this reach of as large as 5.8° with a RMS error of 0.33°c in October 1975 and 0.20 in March 1976. Hydropulsation has a significant effect an the water temperature below Buford dam. These effects are very complicated because they are quite dependent or the timing of the release with respect to both the time of day and past releases.
