ROCK RIPRAP DESIGN FOR PROTECTION OF STREAM …
pubs.usgs.govmaximum-to-mean depth ratio of 1.55 and a ratio of hydraulic radius to mean depth of 0.98, which is independent of width. Most stable channel characteris tics for a given discharge are slope, maximum depth, and hydraulic radius. Volume 2, "Evaluation of Riprap Design Procedures," evaluates seven riprap design procedures now used.

This force, which is simply the pull of water on the wetted area, is known as the tractive force” (Chow, 1959) T = γYS = 62.4 pcf x Depth in feet x Slope of Water Surface
