A foundation or sustaining wall of stones thrown together without order, as in deep water or on a soft bottom, or in a river channel.
Large slabs of stone used as a protective barrier at the edge of a body of water.
Large fragments of broken rock, thrown together irregularly or fitted together (as on the down-stream face of a dam). Its purpose is to prevent erosion by waves or currents and thereby preserve a surface, slope, or underlying structure. It is used for irrigation channels, river-improvement works, spillways at dams, and sea walls for shore protection.
Material, usually rock, placed on slope or bank to prevent erosion.
Broken stone, cut stone blocks, or rubble that is placed on slopes to protect them from erosion or scour caused by flood waters or wave action.
A blanket of appropriately sized stones extending from the toe of slope to a height needed for long term durability.
Irregular broken and randomly sized pieces of rock used for facing bridge abutments and fills; stone thrown together without order to form a foundation, breakwater or sustaining wall.
Rock or other large material that is placed to protect streambanks or lakeshores from erosion due to runoff or wave action.
Stones placed to prevent fast water from scouring and eroding a surface. Large stones (12 by 12 by 6 inches or larger) are hand placed on a setting bed of either aggregate or mortar. With an aggregate setting bed, adjacent stones are butted tightly together. Because of the irregularity of the stones, spalls are used to prevent them from moving. If the stones are placed on a mortared setting bed, the stones may be ½ to 3 inches apart.
(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 stones placed in the water. Riprap protects the shore or some other structure from erosion caused by the currents of the water.
A layer of large, durable fragments of broken rocks specially selected and graded, thrown together irregularly or fitted together to prevent erosion by waves or currents.
A wall or base of rocks placed together irregularly in water flow areas to reduce erosion and scour. Generally it is not held together with mortar or cement but loosely packed, although sometimes it may be held in place with wire.
a combination of large stone, cobbles, and boulders used to line channels, stabilize banks, reduce runoff velocities, or filter out sediment.
A pile of large, angular boulders built seaward of the shoreline to prevent erosion by waves or currents. See also seawall.
Clean limestone or native rock that is 8 inches to 12 inches in diameter or larger.
A layer of large stones or boulders placed together without order, usually used for erosion protection along streams or shore lines.
an unattached rock or stone that is placed on a slope, shore, or embankment, to prevent loss of land due to washing out, erosion, or water movement.
foundation of revetment in water or soft ground made up of irregularly placed stones
A combination of boulders, large stones, and cobbles used to line channels, stabilize banks, filter out sediments, or reduce runoff velocities.
A rubble sustaining wall, often used along shorelines to prevent erosion.
_ A foundation or wall made of broken stones or other erosion-resistant materials (e.g. concrete).
a loose assemblage of broken stones erected to form a foundation in water or on soft ground.
Protective mound of stones placed to prevent erosion of upland areas, roads or structures.
A layer of large uncoursed stones, broken rock, or precast blocks placed in random fashion on the upstream slope of an embankment dam, on a reservoir shore, or on the sides of a channel as protection against wave and ice action.
In the restricted sense, layer or facing of rock or concrete dumped or placed to protect a structure or embankment from erosion; also the broken rock or concrete suitable for such use. Riprap has also been applied to almost all kinds of armor, including wire-enclosed riprap, grouted riprap, sacked concrete, and concrete slabs.
Large stone used to stabilize slopes and shorelines, to construct erosion control structures, and also in building construction and landscaping.
large rocks placed along the bank of a waterway to prevent erosion.
Large pieces of rock (usually 6 to 30 inches in diameter) which have undergone only primary crushing and sizing, or larger, uncrushed pieces. Riprap is used to stabilize slopes and shorelines and construct erosion-control structures.
rock covering used to protect stream banks from erosion.
Loose rock or concrete of varying size, typically brought to a site. Used to protect channel banks from scouring forces.
Rubble such as broken rock placed on a surface to stabilize it and reduce erosion.
a protective covering of stones, with or without mortar, on an earth bed generally laid in a near aquatic environment for the prevention of erosion or wash. Individual stones should measure at least ten inches in one dimension and should have a volume of not less that one third cubic foot to differentiate it form stone mulch
Stones placed on a slope to prevent erosion. Also broken stone used for foundation fill.
Rock or other large aggregate that is placed to protect streambanks, bridge abutments, outflow of drainage structures, or other erodible sites from runoff or wave action.
Usually refers to rocks or concrete structures used to stabilize stream or river banks from erosion.
layer of large, durable materials (usually rocks) used to protect a stream bank or lake shore from erosion; may also refer to the materials used.
an apron of coarse rock installed over the fillslope to prevent erosion.
A protective blanket of large loose stones, 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.
foundation or wall made of broken stones, loosely or irregularly thrown together.
Rock placed on embankment slopes to prevent erosion. pp. 13, 16, 98, and 99.
A layer, facing, or protective mound of stones randomly placed to prevent erosion, scour or sloughing of a structure or embankment; also, the stone so used. In local usage, the similar use of other hard material, such as concrete rubble, is also frequently included as riprap.
Irregularly broken and random-sized large pieces of rock.
Broken rock, cobble, 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 (waves).
Large pieces of broken or crushed durable rock or concrete placed on earth dams and in drainage channels for protection against water erosion.
A layer, facing, or protective mound of broken concrete, sacked concrete, rock, rubble, or stones randomly placed to prevent erosion, scour, or sloughing of a structure or embankment; also, the stone used for this purpose.
Rock facing to support an embankment and prevent erosion, usually at a specific slope such as 2:1
Heavy stones used to protect soil from the action of fast-moving water. True restoration tries to eliminate or minimize the use of riprap, using plants with strong root systems to anchor soil instead (e.g. willows). The use of riprap can lead to many detrimental effects, including increasing water volumes and flow (which leads to flooding and bank erosion), constricting stream channels (which exacerbates flooding), etc.
Forestry Operations & Water Quality] Rock or other large aggregate that is placed to protect streambanks, bridge abutments, fords, or other erodible sites from runoff or wave action.
A protective layer or facing of quarrystone placed to prevent erosion, scour, or sloughing of an embankment or cliff.
Stones or other material placed on a slope to prevent erosion by water.
Loose boulders or concrete piled together along a beach to absorb wave energy before it strikes a cliff face.
Loose stone piled on an embankment or slope to prevent erosion or washing-out.
irregular shaped stones used for facing bridge abutments and fills. Stone thrown together without order to form a foundation or sustaining walls.
Stones used as fill.
Riprap (also known as rip rap, revetment, shot rock or rock armour) is rock or other material used to stabilize shore. Riprap reduces water erosion by resisting the hydraulic attack and dissipating the energy of flowing water or waves. The shape of rock is important.
