Abstract

The physical effects of commercial navigation traffic that can be studied in the field include a resuspension and lateral transport of sediment b sedimentation rates at specific habitats c scour and disruption of substrates caused by tow passage d altered velocity regimen including increased turbulence and reversal of flows e pressure fluctuations, shear force, wave heights, wave wash, and drawdown f changes in water quality parameters and g wave generation. Studies on the physical effects of commercial traffic should be designed to obtain background data and physical effects data as a vessel passes. Background data collection should include ambient velocity and sediment concentration at the site for low, medium, and high flow conditions hydraulic, hydrologic, and morphometric characteristics of the site historical characteristics of the site including sedimentation patterns wind and wave characteristics bed and bank material characteristics basic water quality parameters and other site-specific characteristics such as presence or absence of side channels, backwaters, or tributaries. Information collected as a vessel passes should include several parameters. Keywords Navigation, Commerce, Sediment transport, Habitats, Aquatic biology, Waves, Water quality, Waterways.
