Abstract Details

2016, Master of Science (M.S.), University of Dayton, Civil Engineering.
The Hydrologic Engineering Center’s River Analysis System (HEC-RAS) uses a simulation model to delineate floodplains, but it may also be used to size bridges and culverts. HEC-RAS has an option for defining ineffective flow stations at bridges and culverts. An ineffective flow area is a portion of a river or stream’s cross section where there is no water flowing downstream due to the presence of a bridge or a similar structure, i.e. no conveyance. Current practice is for modelers and engineers to provide an estimate of the location of ineffective flow stations. The purpose of the research effort detailed in this document is to develop an iterative approach capable of quickly and accurately locating ineffective flow stations at bridges. The ultimate goal of the proposed research effort will be to include the methodology in future releases of the HEC-RAS model.
