4. •MOUND SIZING A. Calculate Clean Sand Lift: 3 feet minus Depth to Limiting Condition (1.C) =Clean Sand Lift (1 ft minimum) 3.0 ft - 1.5 ft = 1.5 ft Design Sand Lift (optional): B. Calculate Upslope Height: Clean Sand Lift (4.A) +media depth (1 ft.) + cover (1 ft.) = Upslope Height 1.5 ft + 1.0 ft + 1.0 ft= 3.5 ft 0-34:Slope Multiplier Table Land Slope% 0 t 2 3 4 I 5 6 7 8 9 10 II 12 13 34 15 16 17 18 19 20 21 22 23 24 25 UpSlOpe 3:1 3.00 2.91 2.43 2.75 2.68 2.61 2.54 2.48 2.42 2.36 2.31 2.26 2.21 2.17 2.13 2.09 2.06 2.03 2.00 1.97 1.95 1.93 1.91 1.89 1.87 1.85 Belot Ratio 4:1 4.00 3.85 3.70 3.57 3.45 3.33 3.23 3.12 3.03 2.94 2.86 2.78 2.70 2.62 2.55 2.48 2.41 2.35 2.29 2.23 2.18 2.13 2.08 2.03 1.98 1.93 Land Slope r 0 I 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 [io wnslhpe 3:1 3.00 3.09 3.115 3.30 3.41 3.53 3.66 3.80 3.95 4.11 4.29 4.48 4.69 4.95 5.24 5.55 5.88 6.24 6.63 7.04 7.47 7.93 8.42 8.93 9.46 10.02 Berne Ratio 4:1 4.00 4.17 4.35 4.54 4.76 5.00 5.26 5.5615.88 6.25 6.67'7.14 7.6918.29 8.92 9.57 10.24 10.94 11.67 12.42 13.13 13.99 14.82 15.67 ;6.54 17.44 C Select Upslope Berm Multiplier (based on land slope): 2.94 (figure D-34) D. Calculate Upslope Berm Width: Multiplier (4.C)X Upslope Mound Height (4.6) = Upslope Berm Width 2.94 ft x 3.5 ft = 10.3 ft E. Calculate Drop in Elevation Under Bed: Bed Width (2.B) X Land Slope (1.D) e 100=Drop (ft) 10.0 ft X 12.0 % : 100= 1.20 ft F. Calculate Downslope Mound Height: Upslope Height (4.B) +Drop in Elevation (4.E) =Downslope Height 3.5 ft + 1.20 ft = 4.7 ft Select Downslope Berm Multiplier G.

Calculate Minimum Berm to Cover Absorption Area: Downslope Absorption Width (3.B or 3.C) +4 ft. =ft 16.0 ft + 4 ft = 20.0 ft J. Design Downslope Berm = greater of 4H and 41: 22.0 ft K. Select Endslope Berm Multiplier: 3.00 (usually 3.0 or 4.0) L. Calculate Endslope Berm (4.K)X Downslope Mound Height (4.F)=Endslope Berm Width 3.00 ft x 4.7 ft = 14.1 ft M. Calculate Mound Width: Upslope Berm Width(4.D) +Bed Width (2.6) +Downslope Berm Width (4.J) =ft 10.3 ft + 10.0 ft + 22.0 ft = 42.3 ft N. Calculate Mound Length: Endslope Berm Width (4.L) +Bed Length (2.C) +Endslope Berm Width (4.L) =ft 14.1 ft + 38.0 ft + 14.1 ft = 66.2 ft 0.
