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.

Riprap–Stabilized Outlet - Michigan

Riprap–Stabilized Outlet . Definition . A section of stone or crushed concrete protection placed at the outlet end of the culverts, conduits, or channels. Description and Purpose. The purpose of the rock outlet protection is to reduce the velocity, and energ y of water, such that the flow will not erode the receiving downstream reach.

STANDARD FOR RIPRAP

Riprap for banks shall extend up the banks to the level of the design storm or the top of bank, whichever is lower. In channels where no riprap or paving is required in the bottom, but is required on the banks, the toe of the bank riprap shall extend below the channel bottom a distance at least 8 times the maximum stone size, but in no case more

exception of riprap aprons. Refer to ion 11.6 Sect when designing riprap aprons. This Chapter provides a brief overview on energy dissipators and references HEC 14 for detailed design. With the exception of riprap aprons, the HEC 14 design methods have been automated in the FHWA software HY-8; see Chapter 18 “Hydraulic Software.”
