Summary of the Characteristics of Near-Surface Flow Reversals at the Electrical Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2017, to September 30, 2018 This dataset contains a summary of the characteristics of near-surface flow reversals at the Electrical Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal at Romeoville, Illinois during Water Year 2018 (October 1, 2017, to September 30, 2018). Water velocity near the water surface is measured on a five-minute sampling interval in the EDBS using surface velocity radar at nine measurement cells on a cross section near U.S. Geological Survey streamgage 05536995 (Chicago Sanitary and Ship Canal at Romeoville, Illinois). Flow reversal events are analyzed for each individual cell as well as for the average velocity over all nine cells. For the analysis of individual cells, a flow reversal event is...

Videos were manually screened and analyzed to extract tow characteristics including: date and time of video recording, number and configuration of barges, loading of barges (loaded, unloaded, or mixed), direction of travel, and bow type (rake or box). Only commercial vessels were logged and no identifying data about the tow vessels were maintained. All videos triggered by recreational vessels or other objects were permanently removed from the database during analysis. Any...

This data release is the 2018 water year summary of the EDBS monitoring data. Water surface flow reversals at the EDBS are monitored using surface velocity radar. Commercial vessel traffic patterns through the EDBS are documented using a motion-activated video camera. Temperature and specific conductance are reported in near real-time from USGS sensors installed just downstream of the EDBS.
