Lunch Presentation - Self Cleaning Culverts
Abstract
This presentation will explain the invaluable research that has been performed by the Iowa Department of Transportation regarding the reduction of sediment accumulation in multi-barrel culverts. This promising flume research (IHRB TR-596) determined that the construction of “wedges” in the flared inlet aprons can replicate the approach channel geometry and minimize the accumulation of sediment in multi-barrel culverts. The wedges have been constructed for a triple RCB along IA 1 in Iowa City for site evaluation since December, 2012. The site is under continuous monitoring for sediment load and discharge to monitor the success/failure of the wedges at a site. A site visit of this important research is planned during the conference.
