6 <br />Bank Reshaping Reshaping a severely eroding riverbank may be necessary in order to stabilize <br /> <br />vertical, bare banks. This approach must be coupled with other stabilization techniques because <br />in and of itself it does not provide any stabilization benefits. It only creates a bank with suitable <br />slopes for other stabilization approaches. <br />Favorable 0± ¢³¨¢¤² ¥®± 2¨µ¤±¡ ª 0±®¯¤±³¸ /¶¤±² <br />Managing a riverbank can present a difficult challenge for property owners. Often times, a <br />misunderstanding of factors that contribute to erosion can actually exacerbate the issue. Below is a list <br />of practices that should be followed by property owners adjacent to rivers in order to minimize erosion <br />and protect their property. <br />Avoid mowing near the edge of the bluff or riverbank. Turf grasses have very shallow root <br /> <br />systems, providing little soil stability. Deeper rooted species are also better at filtering out <br />excess nutrients and sediments in runoff. <br />Control runoff from downspouts and other hard surfaces at the top of the slope to prevent it <br /> <br />from flowing over the riverbank. Promote infiltration of rain water into the soil but away from <br />water if necessary. <br />Dispose of yard waste properly to avoid smothering riverbank vegetation and contributing <br /> <br />nutrients to the river, which commonly occurs when leaves and grass clippings are thrown over <br />the riverbank. <br />Plant desirable species with preference for multi-stemmed plants with deep, dense, fibrous root <br /> <br />systems. However, ensure the species are well suited to the soil type, moisture level, and <br />available sunlight or they will not thrive. <br />Prune lower branches on trees to increase the amount of light that penetrates to the ground. <br /> <br />This will increase plant growth at ground level where the stems, roots, and foliage will help keep <br />soil in place. <br />Remove buckthorn, which is an invasive plant that is believed to release a natural herbicide that <br /> <br />suppresses nearby plant growth. <br />Remove fallen trees because they can redirect water toward the bank and exacerbate erosive <br /> <br />river forces. <br />Remove grapevines, which smother trees, shade out understory species, and provide little soil <br /> <br />stabilization benefits. <br /> <br /> <br /> <br />
