<br />WORKS OF IMPROVEMENT FOR POTENTIAL DEVELOPMENT <br /> <br />Possible measures for improvement include rock riprap, <br />ar'chored trees, rock jetties, Jack,;. lIegeta.ted buffel- <br />strips, vegetative sprig revetment, and riparian Zones. <br /> <br />Rock r i prap 15 an effect i ve m"lthod of contro I ling <br />streambank erosion on nearly al I streams, Rock can be <br />placed on straight to severely meandering streambanks. <br /> <br />Anchored trees can be used as an effective method of <br />streambank protection on most streams. They can be used on <br />streams with any degree of meandering. <br /> <br />Rock jetties are an effective mElthod of control I Ing <br />streambank eros i on on s light to moder.ate I y meander i n'l <br />curves, Because jetties function by deflecting the flow <br />away from the streambank they are not practical on sharp <br />curves. <br /> <br />Jacks can be used to stabi I izq most eroding banks, <br />They are especially useful in streams which have wide <br />sections due to streambank meandering, The jacks can be <br />located to a II ow eroded areas to s i It; in beh i nd the I'.OW of <br />Jacks, <br /> <br />Vegetated buffer strip$ for bank protection 15 <br />primari Iy related to cropland which is ti lied up to -:he <ldge <br />of stream channels without leaving a vegetative zone. <br /> <br />Vegetative sprig revetment is one of the most effective <br />methods of control ling stre3mbank o.osion under natural <br />conditions, It is also the least costly method available <br />when the vegetation is maintained in good condition. <br /> <br />Riparian zones along the river )anks wi I I reduce much <br />of the damage associated with streambank erosion. The root <br />systems developed from tree$ and brulh provide protection <br />from the cutting action of water flowing against the banks. <br />The rock drop practices introduced by Dr, Donald R, <br />Reichmuth, PE/LS GEOMAX, PC in his "Living ",ith fOluvial <br />Systems a Short Course on River Mechanics," wer.e not <br />exami ned because of the I ack of i nf~ -mat I on on <br />effectiveness, cost data, and desi9n. <br /> <br />1 1 <br />
