Calcutate Absorption Width: Bed Width X Mound Absorption Ratio =Absorption Width <br /> 10.0 ft X 2.6 = 26.0 ft <br /> B. For SlOpes>1%, the Absorption Width is measured downhill from the upslope edge of the Bed_ <br /> Calcutate Downslope Absorption Width: Absorption Width - Bed Width <br /> 26.0 ft - 10.0 fi = 16.0 ft <br /> 4.
