Length - Slope Factors (L,S)
The slope length (L) and the slope (S) were determined together
according to the equation (Barfield et al . , 1981) :
LS = [ a ]m (430x2 + 30x + 0.43)
72�. � 6.613
where X is slope length, X is sin e e is slope angle and m is an
exponent dependent upon slope given by:
slope < 3%; m = 0.3
slope = 4%; m = 0.4
slope > 5%; m = 0.5
and x = Stream Elevation Difference
The Slope Lengt
x = 0.0969
= 980 ft.
m = 0.5
LS = 4.10
Control Practice Factor (CP)
The control practice factor (CP) was estimated to be 1.00 for fresh
cultivated land with no conservation treatment for a conservative
approach (Barfield et al . , 1981) .
Storage Capacity
The storage capacity of Sediment Pond 004 was also analyzed using the
SEDIMOT II computer program. Table 6 is a summary of the designed
storage capacity.
