FIGURE 15.7 Live Fascines Adapted from USDA, NRCS, Engineering Field Handbook, Chapter 16 363-2134-008 / March 31, 2012 / Page 318
Branchpacking is the alternating of layers of live branches and compacted backfill to repair small scour holes and slips in streambanks. It provides a filter barrier that prevents erosion from bankfull and overbank flows. Branchpacking rapidly establishes a vegetated streambank and enhances colonization by native vegetation. Source Unknown Soil is immediately reinforced. The live branches serve as tensile reinforcement. Once the plant tops begin to grow, the branchpacking system becomes increasingly effective in retarding runoff and minimizing erosion. Sediment trapped by the vegetation refills the hole, while the roots spread throughout the surrounding soil to form a unified mass. The live branches should range from ½” to 2” in diameter and be long enough to reach from the undisturbed soil at the back of the trench and extend slightly from the rebuilt streambank. APPLICATIONS Branchpacking is an effective means of repairing holes in streambanks ranging from 2 to 4 feet in height and depth. It is typically not effective in repairing slump areas greater than 4 feet high or 4 feet deep. INSTALLATION GUIDELINES Divert any concentrated upslope runoff away from the repair area. Prepare the cuttings immediately prior to installation. Install suitable toe protection, such as. properly sized riprap or fiber log, below the streamforming flow elevation (2-year storm elevation = Q2). 363-2134-008 / March 31, 2012 / Page 319
