National Hydraulics Research Program

Laboratory Purpose

The National Hydraulics Research Program includes the J. Sterling Jones Hydraulics Laboratory at the Federal Highway Administration’s (FHWA’s) Turner-Fairbank Highway Research Center. The Office of Infrastructure Research and Development’s Bridge Engineering Research Team (HRDI-40) is responsible for research related to the impacts of flooding on highway infrastructure.

The J. Sterling Jones Hydraulics Laboratory has conducted research on highway hydraulics for more than 30 years. The Laboratory is a state-of-the-art research facility equipped with computational fluid dynamics (CFD) modeling capabilities. The Laboratory’s instrumentation and experimental testing equipment includes a multifunctional flume system, force balance flume, and multiple soil-erosion resistance testing devices that have improved significantly over the past several years. Past research tasks in the laboratory included working on bridge scour, culvert hydraulics and aquatic organism issues, highway drainage concerns, and stream stability problems. The Laboratory has developed design guidelines for bridges that may become submerged in high flood risk areas and guidelines to prevent or combat the effects of scour around bridge foundations..

CFD modeling is conducted through collaboration with the Department of Energy’s Argonne National Laboratory Transportation Research and Analysis Computing Center. This collaboration allows access to high-performance cluster computing. Access to these clusters enables the Hydraulics Laboratory to solve highway hydraulics research problems more efficiently.

 

The photo shows a birds-eye view of the FHWA Hydraulics Laboratory. The tilting flume is on the left. Next to the tilting flume is the computational fluid dynamics (CFD) station, ex situ scour testing device (ESTD), in situ scour testing lab sump device, and the force balance flume (from top to bottom). From top-to-bottom on the right: soil sample preparation station, presentation station, and the fish passage culvert flume.

Research Program

The Hydraulics Research Program is a part of the National Hydraulics Program and is coordinated with the National Hydraulics Team (NHT), including the Program Office (HQ), FHWA Resource Center, and Federal Lands Offices. The research program studies problems related to the six functional areas that were developed by NHT:

  • Hydrology and Extreme Weather
  • Highway Drainage
  • Culvert Hydraulics
  • Bridge Hydraulics
  • Scour, Steam Stability, and Scour Protection (Countermeasures)
  • Coastal Highways

Laboratory Description

The Hydraulics Laboratory is divided into seven zones for better laboratory management, maintenance, and capital improvements. The zones include:

  • Zone 1 – Multifunctional flume system
  • Zone 2 – Force balance flume system
  • Zone 3 – In situ scour testing device (ISTD), lab drill rig
  • Zone 4 – Lab soil erosion testing devices
  • Zone 5 – Particle image velocimetry (PIV), lasers, and cameras
  • Zone 6 – Laboratory office and 3D printing
  • Zone 7 – Laboratory machine shop
