Sedimentology <br /> Particle Size Distribution. The particle size distribution for this sediment pond was <br /> taken from Simons, Li and Associates (Design of Sediment Control Measures for Small Areas <br /> in Surface Coal Mining). This distribution is representative of a sandy loam soil similar <br /> to those described in Tab 9 of the current Nucla Mine permit. <br /> The inputted soil particle distribution is as follows: <br /> Particle Size (mm) Percent Finer <br /> 2.0000 100.0 <br /> 1.0000 100.0 <br /> 0.1000 85.0 <br /> 0.0500 80.0 <br /> 0.0020 20.0 <br /> 0.0001 0.0 <br /> The specific gravity of the soil and the submerged bulk specific gravity were estimated <br /> based on the references cited above. Specific gravity and submerged bulk specific gravity <br /> were estimated to be 2.5 and 1.25, respectively. <br /> Length-Slope Factor (L,S). The slope length (L) and the slope (S) were determined <br /> together accordjr�g to the equation: <br /> X\LS = [ ]m (430x 2 + 30x + 0.43) <br /> 72.6 6.613 <br /> where Xis slope length, X is sin 6, Ais slope angle and m is an exponent dependent <br /> upon slope given by: <br /> slope <3% m = 0.3 <br /> slope = 4% m = 0.4 <br /> slope > 5% m = 0.5 <br /> 8 <br />
