Add depth of dean sand for separation (2a) <br />at upslope edge, depth of rock layer (1 foot) to depth of <br />cover (1 foot) to find the moimd height at the upslope edge <br />of rock layer; <br />ft + 1ft + 1ft = feet <br />d. Enter table with landslope and upslope dike ratio. <br />Select dike multiplier of ^ <br />e. Multiply dike multiplier by upslope mound height <br />to find upslope dike width: x 3.0 = /o feet <br />f.
