摘要： The erosion control system includes a plurality of erosion control blocks connected to one another by connectors to form an interconnected network of erosion control blocks conforming to the underlying terrain for erosion prevention. Each erosion control block includes a plurality of apertures therethrough each forming a side wall. The connector includes a pair of projecting legs for insertion into adjacent erosion control blocks. Each leg attachingly engages the side wall of the aperture of an erosion control block for connecting that erosion control block to an adjacent block. The legs include tapered extensions which frictionally engage the side wall, and in one embodiment of the erosion control block, the side wall includes a shoulder which engages the terminal end of the tapered extension. The erosion control block may have one end with convex arcuate surface and another end with a concave arcuate surface for providing an articulating joint between adjacent erosion control blocks. The erosion control block also may include a plurality of horizontal hydraulic grooves in the bottom planar surface of the block for hydrostatic relief.
