taken in April of 1986 from a reclaimed spoils area since most of the <br />46) watershed is reclaimed area. The input particle distribution is as <br />follows: <br />Particle Size (mm) <br />Percent Finer <br />127.0 <br />100 <br />11.2 <br />82 <br />2.0 <br />78 <br />1.0 <br />76 <br />0.50 <br />74 <br />0.25 <br />72 <br />0.106 <br />69 <br />0.045 <br />33 <br />0.020 <br />29 <br />0.010 <br />20 <br />0.005 <br />15 <br />0.002 <br />11 <br />0.001 <br />8 <br />0.0001 <br />0 <br />Specific gravity and the submerged bulk specific gravity of the sediment <br />were estimated to be 2.50 and 1.25, respectively. <br />The slope length (L) and the watercourse slope (S) were determined <br />according to the equation for a Length Slope Factor (LS) (Barfield et <br />al, 1981). <br />LS f ), m 430x + 30x + 0.43 <br />72. 6.613 <br />Where � is slope length, x is sin A , 6 is slope angle, and m is an <br />exponent dependent upon the slope given by: <br />slope t 3 %; m = 0.3 <br />slope = 4 %; m = 0.4 <br />slope ? 5 %; m = 0.5 <br />7 -6a -3 Revised 8/27/86 <br />
