903.5.5 Mound Widths
JUMP TO FULL CODE CHAPTER
(Equation 9-6)
(Equation 9-7)
The mound width for a bed system shall be determined by the following equation:
(Equation 9-6)For SI: 1 foot = 304.8 mm.
The mound width for a trench system shall be determined by the following equation:
(Equation 9-7)For SI: 1 foot = 304.8 mm.
where:
J = 3(D + F + G)SU
I = 3(E + F + G)SD
The upslope correction factor (SU) and the downslope correction factor (SD) shall be determined based on the slope in accordance with Table 903.5.5.
