Flow model of Saginaw River near Saginaw, Michigan
David J. Holtschlag
1981, Open-File Report 81-1061
An unsteady-flow simulation model was applied to a 19.5-mile reach of Saginaw River. The model provides a method of determining instantaneous discharge for flows from -8,000 to 12,000 cubic feet per second. The currently used slope-rating method can be utilized to compute discharge only under steady and high-flow conditions. Unsteady...
