摘要：
A flow in the upper plane bed regime is studied. The authors use their experience with slurry flows in pressurized pipes to evaluate intense bed-load in flows with free surface. Special attention is paid to the effect of the delivered concentration of sediment on bed friction. Experimental data from laboratory flumes are compared with predictions by transport-and friction formulae. The formulae were derived originally for the upper plane bed regime in slurry pipes and they were calibrated by pressurized-pipe data.
