Riprap and Boulder Placement
Rock riprap is the controlled placement of large angular rock such as (stone, cobbles, and boulders) over soil. The purpose of riprap is to protect the soil from erosion forces and to improve the stability of slopes that are subject to seepage or have poor soil structure. Over-steepened slopes are commonly stabilized utilizing boulder placement and soil stabilization construction techniques.
The application of rip rap protects culvert inlets and outlets, stream banks, drainage channels (as a lining), or other areas subject to erosion by storm water runoff. Rock and other materials are also used to armor shorelines, streambeds, bridge abutments, pilings and other shoreline structures against scour and water or ice erosion.
Practical Applications
-
Cut or fill slopes subject to seepage or weathering, particularly where conditions prohibit establishment of vegetation.
-
Channel side slopes and bottom.
-
Inlets and outlets for culverts, bridges, slope drains, grade stabilization structures, and storm drains; where the velocity of flow from these structures exceeds the capacity of the downstream area to resist erosion.
-
Stream banks and stream grades.
-
Shorelines subject to wave action
Advantages
-
Rip rap offers an easy-to-use method for decreasing water velocity and protecting slopes from erosion.
-
It is simple to install and maintain.
-
Rip rap provides some water quality benefits by increasing roughness and decreasing the velocity of the flow, inducing settling.
