• Length-Slope Factor (L,S) <br />The slope length (L) and the slope (S) were determined together according <br />to the equation: <br />LS - a m 430x2 + 30x + 0.43 <br />X72.6 ~ ( 6.613 ) <br />where a is slope length, X is sin e, a is slope angle and m is an <br />exponent dependent upon slope given by: <br />slope < 3%; m = 0.3 <br />slope = 4% m = 0.4 <br />slope > 5% m = 0.5 <br />x = Stream Elevation Difference <br />T e S ope engt <br />• where: x = 610 = 0.244 <br />~,3~~ <br />a = 2,500 ft. <br />m. = 0.5 <br />LS = 29.59 <br />Control Practice Factor (CP) <br />The control practice factor (CP) was estimated to be 1.00 for fresh <br />cultivated land with no conservation treatment (Barfield et al., 1981). <br />Storage Capacity <br />The storage capacity of Sediment Pond 008 was also analyzed using the <br />SEDIMOT II computer program. Table 7-6e-7 is a summary of the designed <br />storage capacity. <br />• <br />7-6e-10 <br />
