In cases where an open channel needs bed and bank protection riprap is a common lining material, of which riprap size is the main design parameter needing determination. The current solution procedure is a cumbersome iterative one. A direct solution (one not needing iteration) is proposed here that improves computation time by 98% and adds less than 8% error.
