<br />~: Felled trees, found along the adjacent bank, can be laid butt upstream, parallel <br />to and against the toe of <!rodlng bank, and anchored to stumps or trees with used cable. <br />This will tend to build up a foreshore by causing the current to slow down and drop part <br />of Its silt load. This Is . relatively Inexpensive method. <br /> <br />~: $I,500/tree, Including stone fill and deadman anchors. Assuming 75-foot spacing, <br />cost equals $20/bank-foot. <br /> <br />MAINTENANCE REQUIREMENTS: HeplacOOlent of trees or rearrangOOlent of moved trees. <br /> <br />ENVIRONMENTAL ASPECT: This technique consists of anchoring of trees perpElndicular to the <br />riverbank. The branches of the tree rest on the riverbed. The trees protect the eroding <br />bank by slowing the curren"" and accumulating debris. This technique Is more natural In <br />that It simulates the natural occurrence of undercut trees fal ling Into the stream. The <br />bank! fne receives only miner disturbances, and the trees provide fish habitat. Although <br />some trees are lost for bank protection~ this erosion control method Is the roost <br />environmentally acceptable as it is harmonious with the flood plain landscape, and <br />attempts to reproduce a natllra I phenomenon. <br /> <br />20 <br />
