Rocks or other materials used to shore up an embankment, deter or prevent erosion, guide shipping, or serve as a temporary mooring
A layer of broken rock placed on a riverbank to prevent erosion, scouring or slumping
(1) Broken STONES used for REVETMENT, TOE protection for BLUFFS, or structures exposed to WAVE action, foundations, etc (2) Foundation of wall or STONES placed together irregularly (3) (SMP) A layer, facing or protective mound of STONES placed to prevent EROSION, scour or sloughing of a structure or EMBANKMENT; also the STONE so used
A pile of large, angular boulders built seaward of the shoreline to prevent erosion by waves or currents See also seawall
{i} pile of broken stones used for foundations (in water or on soft grounds) or embankment; foundation made of broken stones put together loosely; stone wall used as a barrier to break the force of waves; material or stones used for riprap
Large boulders, rocks, or clean concrete rubble used to protect a shore, wall, or bank of earth from the force of waves or erosion
Broken rock, cobbles, or boulders placed on earth surfaces, such as the face of a dam or the bank of a stream, for protection against the action of water
A light weight stone covering used to protect soil or surface bedrock from erosion by water or the elements
A facing layer (protective cover) of stones or other material placed to prevent erosion or the sloughing off of a structure or embankment
a combination of large stone, cobbles, and boulders used to line channels, stabilize banks, reduce runoff velocities, or filter out sediment
Large, durable materials (usually rocks; sometimes broken concrete, etc ) used to protect a stream bank or lake shore from erosion; may also refer to the materials used
Aggregate material placed on potentially erodible sites to reduce the impact of rain or surface water runoff on these areas
A foundation or sustaining wall of stones thrown together without order, as in deep water or on a soft bottom
protective covering material (such as blocks, brickbats, or stones) deposited on water beds, banks, and shores to prevent erosion and scour
A layer of large uncoursed stones, broken rock, boulders, precast blocks, bags of cement, or other suitable material generally placed in random fashion on the upstream and downstream faces of embankment dams, stream banks, on a reservoir shore, on the sides of a channel, or other land surfaces to protect them from erosion or scour caused by current, wind, wave, and/or ice action A protective blanket of large loose stones, which are usually placed by machine to achieve a desired configuration Riprap is usually placed by dumping or other mechanical methods but, in some cases, is hand placed It consist of relatively large pieces as distinguished from a gravel blanket Very large riprap is sometimes referred to as "armoring " All four dams at Horsetooth are covered with riprap The riprap will be removed and eventually replaced as part of the construction
Material such as rock, logs, and concrete which is placed along a watercourse to stabilize the banks
Rock or other large material that is placed to protect streambanks or lakeshores from erosion due to runoff or wave action
rocks, irregularly shaped, and at least six (6) inches in diameter, used for erosion control and soil stabilization, typically used on ground slopes of two (2) units horizontal to one (1) unit vertical or less
