Field experiments were conducted under the Alluvial Channel Observation Project (ACOP) to obtain data on the hydraulic, sedimentation and morphologic aspect of alluvial hydraulics. One of the objectives of the research program is to develop predictive relations for the behavior of straight sand bed channels flowing in an equilibrium state. The present report is based on 203 equilibrium runs. 收起
