A probabilistic approach to borrow sediment selection in beach nourishment projects

摘要

A probabilistic approach is used to assess borrow material stability on artificially nourished beaches. A stability factor (sf) is attributed to each grainsize fraction of the native sediment based on its cumulative curve. Sum of these sf, weighted with the frequency of each grain size fraction of the borrow material, gives the Stability index (Si) with values between 1 (completely stable) and 0 (completely unstable).
