conditions. Continued observations will be made of this area for problems or necessary <br />maintenance. <br />On slopes where no Swale or defined channel exists, regrading, or disking, or chisel plowing <br />will be performed, depending on the extent of the erosion. Reseeding will then take place. <br />In addition to fhe above, contour furrows in and above the erosion area may be constructed <br />to trap and slow down the runoff. Straw dikes can also be used where appropriate to <br />control runoff and promote revegetation. <br />If corrective measures described above fail, WFC proposes to observe and reevaluate the <br />situation. A combination of the first two methods described or some variation therein will be <br />applied. These activities can include, but are not limited to, rock channels, contour furrows or <br />laterals with rock or matting bottoms, V ditches made with the dozer or motor grader, and <br />subsequent revegetation. <br />Head cutting in channels will be controlled by a number of methods. If the area is at a point that <br />concentrates runoff, the area will be improved to accept this runoff. This would Include reshaping <br />the channel and channel bottom, covering with erosion matting, seeding, or rocking. Inlet channel <br />erosion will be controlled down to the average water level of the ponds. Remedial action on pond <br />slopes will extend as far down the slopes as equipment access allows, which at a minimum will be <br />below the level of the principal spillway of each pond. <br />In other areas, depending on the extent of erosion and time of year, the area will be regraded, <br />disked, and seeded as needed. Straw bales, erosion matting, or rock fill may also be used to <br />stabilize the area. Pond 007 will remain for stock use by the landowner. <br />Design Methodolouv. The precipitation runoff (peak flow and volume) is estimated using the Soil <br />Conservation Service (SCS) triangular hydrograph techniques. <br />Design of Small Dams (U.S. Dept. of Interior, 1977). Computations necessary for this runoff <br />estimating technique have been computerized by various individuals and agencies. SEDIMOT II <br />was developed by Research Specialist Bruce N. Wilson, Professor Billy J. Barfield, and Assistant <br />Professor Ian D. Moore at the Department of Agricultural Engineering, University of Kentucky, <br />Lexington, Kentucky. This program was used to estimate runoff peak flow and volume necessary <br />for the design of sediment ponds 001, 002, 003, 004, 005, and 006. SEDCAD program was used <br />. for the design of Pond 007. <br />(REVISED 12100) 2.05.3(3) - 7 <br />
