<br />Streal.l Bank Erosion Control \lith Jacks <br /> <br />Jacks can be used to stabilize most eroding banks. Jacks are especially use- <br />ful in streams which have wide sections due to stream bank meandering. The <br />jacks can be located to allow eroded areas to silt in behind the row of <br />jacks. On smaller streams and streams with fairly low flow velocities, a <br />single row of jacks is all that would be required. The jacks can be fabrica- <br />ted from wood, concrete or metal. Individual jacks are fabricated by tying <br />three posts or beams in a cross shape with wire. The jacks are placed along <br />the toe of the bank. Rock is placed on and around the base of wood jacks to <br />keep them from floating. The jacks are anchored to the bank with cable and <br />deadman anchors. Vegetation should be established in the area behind the <br />jacks. <br /> <br />~aintenance requirements for this practice include inspecting the jacks and <br />repairing any loose or broken wires. Any movement of the jacks or rock should <br />be corrected by returning it to its original location. Any scour holes or <br />other erosion which has occurred behind the jacks should be reshaped and <br />revege ta ted. <br /> <br />48 <br />
