Annual sediment discharge and bed-load estimates for gaging stations on the Middle Yuba and South Yuba Rivers in the upper Yuba River watershed, California.
[Annual suspended-sediment discharge estimated using seasonal suspended-sediment rating curves. Annual bed-load discharge estimated using mixed-sediment model (Wilcock and Crowe, 2003). Total annual sediment discharge equals annual suspended-sediment discharge plus annual bed-load discharge.
