 Riprap (also known as rip rap or shot rock) is rock or other material used to stabilize shore. Riprap reduces water erosion by dissipating the energy of flowing water or waves. The shape of rock is important. Course, angular rock, usually made by crushing or blasting, is more effective at ground reinforcement than round river rock. A correct mixture of aggregate size can also aid riprap's ability to create an interlocking structure. Image File history File links Riprap. ...

Riprap is graded by size. A specified diameter will have fifty percent of the rock (by weight) larger and fifty percent smaller. The velocity of water flow is generally the determining factor for size of stone. Riprap varies in size from several centimeters to cast concrete shapes several meters across. The size and material will be specified by a civil engineer or local building code. In modern usage, civil engineering is a broad field of engineering that deals with the planning, construction, and maintenance of fixed structures, or public works, as they related to earth, water, or civilization and their processes. ...
