Summary

The primary objective of this report is to outline procedures that can be used for the measurement and analyses of physical data to measure changes that are generated with the movement of navigation traffic in large rivers. Part I of the report contains summaries of recent investigations of navigation studies and basic considerations in the extrapolation of the data for system-wide application. Part II provides a description of the various hydraulic, sediment transport, and vessel-induced parameters that need to be considered in navigation studies. Some theoretical backgrounds are given for velocity fluctuations, turbulence intensity, velocity distributions, and sediment transport characteristics of rivers. Part III considers the basic [...]
