Abstract: The U.S. Army Engineer Division, Ohio River, directs the operation of flood-control reservoirs as well as navigation locks and dams on the Ohio River and its tributaries. A one-dimensional mathematical model, FLOWSED, for predicting flow conditions on the Ohio River as a result of these activities is discussed. The basic numerical technique used in the model is an extension of work by Y. H. Chen on the upper Mississippi River. As the name implies, FLOWSED computes flow conditions as well as sediment movement. The work reported herein emphasizes the flow computations with coefficients selected to make the sediment transport negligible. FLOWSED is an implicit finite difference model that provides the capability of modeling a system containing any number of tributaries. In addition, FLOWSED models the influence of locks and dams in the system as well as levee overtopping. The system modeled herein consists of the complete Ohio River from Pittsburgh, Pa., through its junction with the Mississippi River plus 12 tributaries. Applications to various portions of the system using observed 1964, 1972, and 1976 flood data have been made and results are presented.
