Alternative Techniques to Riprap Bank Stabilization
www.fema.govfish. Riprap also tends to suffer from structural integrity issues during and after high-water events. Losing rocks to high water or fast flows, a riprap structure will soon begin to fail in its purpose. Once the soil that the riprap is designed to protect is exposed, the damage continues as before its installation.
Design of Rock Riprap for Bank Stabilization
dnrc.mt.govMar 07, 2012 · Riprap Design Hydraulics (continued) Tractive Force “When water flows in a channel, a force is developed that acts in the direction of flow on the channel bed. 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

Riprap–Stabilized Outlet - Michigan
www.michigan.govDesign Specifications . General Considerations The design of rock outlet protection depends entirely on the location. P ipe outlet at the top of cuts or on slopes steeper than 10 percent, cannot be protected by rock aprons or riprap sections due to re-concentration of flows and high velocities encountered after the flow leaves the apron.
