397865 - An Efficient Method to Analyze Mesoscale Hydrodynamic Processes Using a Coordinated Physical/Numerical Modeling Strategy

Tuesday, June 5
8:30 AM - 10:00 AM
Location: Greenway CD

With the advent of a significant advancement in computational speed, storage, graphical visualization, There has been a renewed belief that the need to physically observe hydrodynamic processes in the field and use physical models is obsolete. This hubris is no more valid today as it was when numerical modelers made advances in the 1970’s 1980’s, and 1990’s. Analysis of complex flow problems must regard these two approaches as complimentary, not exclusionary. Any river project can have significant complicating factors, and will significantly benefit from analysis beyond a simple 1-D numerical approach.
This presentation demonstrates an analysis strategy that efficiently employs both numerical modeling, and physically modeling, yielding superior hydrodynamic designs. The authors will present their “Physical First” procedural methodology that can be employed efficiently to analyze complex hydrodynamic problems minimizing and often eliminating costly parallel analysis using both numeric and physical modeling. Through numerous case studies the authors will demonstrate that this methodology can be employed without the need for large costly laboratories. Finally the presentation will show that this strategy can be effectively and efficiently employed even for hydraulic projects that are models in physical extent.

Jerry R. Richardson, M.ASCE, D.WRE

Associate Professor
University of Missouri Kansas City

Dr. Richardson is an Associate Professor of Civil Engineering at the University of Missouri - Kansas City and director of the River Engineering Program. He is also a Senior Water Resources Engineer Water Resources Solutions (WRS) LLC.
Dr. Richardson received his BS, MS, and Ph.D. in Civil Engineering at Colorado State University. He contributed most of the artwork to the first edition of FHWA’s Highways In the River Environment (HIRE) and edited the second edition. In the early 1970’s he worked in Venezuela serving as a field technician gaging streams and servicing the rain gage network for a large basin-wide hydrologic project.
In 1980, he worked in Alaska conducting hydraulic, stream stability, and scour analysis studying river crossing of the Northwest Alaskan Gas Pipeline. After his Master’s degree where he conducting laboratory studies of inflow seepage effects on sediment transport, worked on the island of Java investigating the riverine consequences of the volcanic eruption of Galungung for the USAID.
Dr. Richardson completed his Ph.D. in 1989, and then worked to develop training resources for assessing Stream Stability and Scour at bridges for FHWA and NHI. Dr. Richardson was a contributing author of the original editions of FHWA’s HEC-18 and HEC-20. He is a certified NHI instructor for 27 years.
Dr. Richardson joined the University of Missouri Kansas City in 1994 where he teaches and conduct research in the field of river engineering, river mechanics, sediment transport, and scour at bridges. Dr. Richardson has trained thousands of engineers, published over 25-refereed publications, numerous conference articles and contributed to numerous reports, circulars, manuals and articles.
