Abstract: Fish and other aquatic species occasionally become entrained in dredges during operation. To better predict the likelihood of this entrainment occurring, the U.S. Army Corps of Engineers, San Francisco District, contacted the U.S. Army Engineer Research and Development Center (ERDC) to conduct a numerical model study to determine the flow behavior surrounding a draghead during operation. The validation data were taken from a previously completed 1:7-scale physical model study of a California draghead.1 The numerical model study was completed by validating the numerical modeling process and then performing simulations at prototype scale to provide appropriate velocity measurements in the field. This report focuses on the numerical modeling process and validation portion of the numerical model.
