Abstract: A numerical river ice model is applied to an 85-mile reach of Alaska's Susitna River immediately downstream of the proposed Susitna Hydroelectric Project. The model is designed to forecast the effects of the proposed 2-dam project on river ice processes and corresponding water surface elevations in the river downstream of the dams. The river ice model provides a daily summary of hydraulic, temperature and ice conditions within the study reach. Observations of river ice processes on the Susitna River have been documented for the past five winters and provide the basis for calibration of the river ice model. The calibrated model is then extended to simulate river ice processes with the proposed project in operation.
