F. ABSORPTION WIDTH Absorption ratio: 2 <br /> ' 1, AbswpGon width equals absorption ratio times rodc tayer width <br /> 2.00 x 10.0 ft = 20.0 ft <br /> G. MOUND SLOPE WIDTH d�LENGTH(Greater than 1%) , <br /> 1. Downslope absorption width=absorption width minus rock layer width <br /> 20.0 feet - 10.0 feet= 10.0 ft <br /> 2.
