Methodologies for the determination of flow duration curves at specific sites on ungaged reaches of streams Item Info

This thesis study examines several techniques for synthesizing flow duration curves, at ungaged river sites for application to hydro-electric energy surveys of entire river systems. Three techniques are presented which can be utilized on natural flowinq rivers. Data requirements consist of existing streamflow records and compilations of area-precipitation products. The procedures are based on regression equations and normali zation of existing flow duration curves. The three techniques are applie d to the Clearwater River in Idaho and a comparison of their results is made. A fourth technique is presented for synthesizing flow duration curves for regulated streams using similar data input as for the three natural flow Methods. This procedure is applied to the requla��t .ed portions of the .Priest and Payette Rivers in Idaho. The Method is also applicable to natural streams and this is illustrated by application to the Clearwater river. Comparisons of synthetic results to actual discharge and energy valu���s for various exceedance percents alcng with percent differences is prese nted to give indications of error maqnitudes.
