TīmeklisThe Riprap Calculator uses the Maynord equation to compute riprap size. The Maynord equation computes the 30 th percentile rock size that should remain stable at the design velocity on the channel bed and on the side slope. Because of the gravitational component, the stable rock size on the side slope will be larger than the bed.
