CONCRETE BLOCKS GAIN ACCEPTANCE AS EROSION-CONTROL SYSTEMS

The article describes the use of precast concrete blocks that interlock together in one or more planes to resist displacement caused by the action of a hydraulic force. Since the blocks allow free movement between the individual units, they are called articulating block systems (ABS). The ABS protects and holds in place a filtering system which is invariably a geotextile. The design requires a systems approach that takes into account the soil to be protected, the geotextile, the articulating concrete block system and any cable or anchors used as system components. ABS projects are always installed on a slope or flat channel bottom. The article describes both cabled and noncabled systems, as well as the two primary types of hydraulic forces that are considered in the design of erosion control projects: wave attack and high-velocity flows. It also describes one of the benefits of ABS revetments, namely, their ability to support vegetation. Construction priorites are noted as well as the design of the filter layer.
