Stormwater Management Manual for Eastern Washington Update Seminar


Hydraulic Design of Bridges Using HEC-RAS

Date: Tuesday, April 30, 2019
Time: 06:00 PM
Location: PACCAR (Applied Sciences) GU
Address: 502 E Boone Ave, Spokane , WA 88258 (Map)

ASCE Inland Empire Section is pleased to present a four day workshop on the use of the hydraulic
modeling tools in HEC-RAS. The hands-on workshop will cover the application of HEC-RAS (1D) to
complete the hydraulic design of a bridge. It will cover topics such as flow determination, gradually
varied flow, calibration and verification of existing water surface profiles, incorporating uncertainty in
Manning’s rough coefficients, modeling bridge hydraulics, setting ineffective flow areas, sizing the
bridge opening, troubleshooting model warnings and notes, meeting FEMA no rise requirements,
and analysis of bridge scour. The class will also include a basic introduction to HEC-RAS 2D (not
at bridges) and provide a discussion on the applicability of 2D vs 1D modeling and an example 2D
application. The guiding principles both 1D and 2D HEC-RAS models will be discussed throughout
the workshop.

This workshop will take place on Tuesdays and Thursdays over two weeks. It will cover:


> Review of Open Channel Flow and Hydraulic Design of Bridges
> Intro to Course Project, Existing Conditions Model, Calibration and Verification
> Proposed Conditions Model, Bridge Modeling Approaches, Final Bridge Design
> Bridge Scour Analysis, Intro to HEC-RAS 2D


The instructor for the workshop is:
> Dr. Sue Niezgoda, PhD, PE, Gonzaga University


This course qualifies for 12 PDH continuing education hours.
