Regular inspection and monitoring of upstream slope protection is essential to detect any problems. It is important to keep written records of the location and extent of any erosion, undermining, or deterioration of the riprap, wave berm or other slope protection. Photographs provide invaluable records of changing conditions.

riprap is further subdivided by placement method into placed riprap, hand-placed riprap, and plated riprap. Placed riprap is graded stone put on a prepared slope in such a manner that segregation will not take place. Placed riprap forms a layer of loose stone; individual stones can independently adjust to shifts in or movement of the base material.
