EMTC 93-R015. 5 pp. (NTIS #PB94-108966) ABSTRACT This paper examines the characteristics of waves and drawdown generated by barge traffic in inland waterways. The analysis was made on the basis of field data for 77 events collected from several sites along the Illinois and Mississippi Rivers. To illustrate the range of variations in waves and drawdown in the inland waterways, three case studies were selected. A synchronized comparison between waves and drawdown, local velocity, and turbidity level at the nearshore zone is also presented.
