摘要

The efficacy as roadside channels of four typical Alabama soils and grass and concrete linings were investigated at different flows and slopes. The characteristics of erosion and sedimentation were observed for the channels tested. All of the soils tested were found to silt at the upper end of the channel and erode at the lower portion. The grass lined channels did not erode but silted the entire length of channel at all slopes and flows investigated. The concrete channels silted at the low slopes from the upper end to near the lower end of the channels, but the sediment was carried away at the steep slopes. (Aurthor)
