ROCK RIPRAP DESIGN FOR PROTECTION OF STREAM …

preparing rock riprap bank protection. Typical channels were found to have a maximum-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.
