COURSE DESCRIPTION:

Two-Dimensional HydraulicModeling of Rivers at Highway Encroachments (135095) provides participants with instruction to understand and appropriatelyapply 2D hydraulic models of rivers in highway encroachment situations.

The course focuses on the use andapplication of the SRH-2D model, developed by the US Bureau of Reclamation(USBR) and sponsored by the USBR and FHWA. Modeling principles and techniqueswill be presented using the latest version of the Surface Water Modeling System(SMS), a graphical pre-and post-processor for several 2D modeling engines,including SRH-2D. Specific lesson topics include model terrain andbackground data, modeling parameters, mesh development, modeling hydraulicstructures, calibration, model review, extracting bridge scour parameters, andmore.

SRH-2D, Sedimentation and RiverHydraulics - Two-Dimensional model, solves the 2D dynamic wave equations forwater surface elevation, water depth, and depth-averaged velocity using thefinite volume numerical method. Other output variables include Froude number,bed shear stress. The model uses a flexible mesh and adopts very robust andstable numerical schemes with a seamless wetting-drying algorithm. The modelcan be run in steady state or unsteady mode and can simulate all flow regimessimultaneously without the need for special treatments. Computations athydraulic structures are performed using standard FHWA methods and procedures,including HY-8, which is embedded in the program to perform culvertcalculations. Pressure flow conditions at bridges and large culverts arecomputed at each element to provide detailed results for simple to fairlycomplex bridge configurations.

SMS iscapable of interactively building the finite volume mesh for SRH-2D, as well asthe input data files necessary to use the SRH-2D model. The program also hasnumerous options for graphically displaying the output from SRH-2D to effectivelycommunicate the results of the hydraulic analysis to a non-technical audience.The SMS-SRH-2D interface also includes a Bridge Scour Tool that may be used toextract the hydraulic parameters from multiple simulations to support bridgescour computations in the FHWA Hydraulic Toolbox or other user preferred methods.

OUTCOMES:

Upon completion of the course, participants will be able to:

  • Describe the differences between 1D and 2D hydraulic models
  • Use background data in SMS for 2D modeling projects
  • Use SMS to setup and run 2D models
  • Generate and review 2D model results
  • Insert structures into 2D models
  • Evaluate 2D hydraulic parameters for use in bridge scour analysis

TARGET AUDIENCE:

The target audience for this course is FHWA and stateDepartment of Transportation hydraulics personnel and other Federal, state,local or consulting engineers who have responsibility for, or desire to workwith, the hydraulic analysis and design of highway river crossings. Courseparticipants should have knowledge of the fundamentals of open channel flowhydraulics. It is suggested (but not required) that course participants takeNHI course 135091-Basic Hydraulic Principles Review (WBT).

If you have questions about this NHI training, please contact NHI at nhicustomerservice@dot.gov or 877.558.6873.


PREREQUISITES:

Course participants should have knowledge of the fundamentals of open channel flow hydraulics. The free web-based training course, NHI 135091 Basic Hydraulic Principles Review, is available for those wishing to refresh their knowledge.
