Ketcheson, Gary L. Sediment rating equations: an evaluation for streams in the <br />Idaho batholith. General Technical Report INT-213. Ogden, UT: U.S. Department <br />of Agriculture, Forest Service, Intermountain Research Station; 1986. 12 p. <br />Sediment data from streams in the Idaho batholith were used to develop sus- <br />pended, bedload, and total sediment rating equations. These equations are dis- <br />cussed in terms of statistical significance and their usefulness for documenting <br />management impacts. Sediment yields were estimated using the rating equa- <br />tions and streamflow data. These yields were compared with those estimated <br />from a time-integration method. For streams in the Silver Creek research area, <br />sediment yields from rating equations and time-integration techniques were <br />compared with estimates from sediment dams. Rating equation and time- <br />integration estimates were statistically different. Time-integration estimates <br />more closely matched those from the sediment dams. <br />KEYWORDS: rating equations, sediment, sediment yield, suspended sediment, <br />bed load
