Description
Summary:This paper presents the research results of statistical parameters associated with turbulence in a natural river caused by the movement of navigation traffic. Movement of navigation traffic within restricted inland waterways, such as the Illinois, Mississippi, or Ohio Rivers, changes their flow characteristics temporarily in space and time. These spatial and temporal changes must be quantified in order to assess their effects on biologically sensitive areas, and they have seldom been evaluated for natural waterways. Data are collected from the Illinois River to evaluate these changes. The longitudinal and lateral components of fluctuating velocity (u′,v′), Reynolds stress (-ρu′v′¯), turbulent intensities (σx,σy), turbulent kinetic energy (TKE), and maximum return velocity generated by navigation traffic are analyzed here. Results have shown that significant changes occur in all of these parameters. The largest changes take place in a zone within 10% of the channel width from the shore.
