ESTIMATING FLOW THROUGH RIPRAP

A series of 19 flume tests was conducted, in which flow was routed through a riprap layer, and the average interstitial or through-flow, velocity was measured and recorded. Flow measurements varied plus/minus 40% about the average velocity. A predictive relationship was developed in which the average interstitial velocity was determined to be a function of the embankment slope and rock size. The predictive relationship provides the designer with a method for estimating through flow based upon a representative stone size, gradation, and embankment slope.
