Abstract : This report presents a simplified design method for riprap sizing that allows adjustment of riprap size for specified safety factor, bend placement, side slope placement, specific weight, stone shape, channel shape effects, and roughness effects. It presents design nomographs for each of four sizing methods: Isbash, tractive force-logarithmic profile, tractive force-power profile, and Froude method. Method differences and advantages are explored. This report also discusses various practical riprap design considerations including transition design, strip roughness, and flow types. Examples are included.
