This event qualifies for 19 PDH

To protect the health and safety of attendees, this event has been rescheduled due to COVID-19 concerns. 

New Date: 10/27-10/29/2020


This is an Interactive seminar focused on application and benefit of two-dimensional flow capabilities of HEC-RAS, specific to the dam safety industry. The course will maintain a balance between both lecture-style presentations on model theory and hands-on workshop sessions for examples of model applications. Topics will include applications and benefits of HEC-RAS 2D modeling; RAS Mapper and terrain preparation; running 2D models including dam, levee, and breach modeling; viewing results with RAS Mapper; troubleshooting and model review.


Learning objectives attendees will receive from this course:

  • Understand when and where to use HEC-RAS 2D
  • Develop necessary input/terrain data for HEC-RAS 2D
  • Create and run a HEC-RAS 2D model
  • Troubleshoot and review a HEC-RAS 2D model
  • Utilize HEC-RAS 2D for various dam safety applications

The course will include a refresher of open channel hydraulic theory and an overview of use and capabilities of HEC-RAS . However, intermediate HEC-RAS experience or advanced experience using other numerical modeling software is a recommended prerequisite for the course. It is also recommended that attendees have some HEC-RAS 1D experience including ASDSO’s HEC-RAS Course.

Speaker and Presenter Information


Patrick Miles
Project Manager & Engineer
Freese & Nichols, Inc.

As a member of FNI’s Water Resources Design Group, Patrick specializes in hydrologic and hydraulic modeling for dam, levees, canals, spillways, and related structures for assessments, comprehensive reviews, rehabilitation design, Probable Maximum Flood analyses, breach analyses and levee certifications. His H&H modeling abilities include significant experience in HEC-HMS and HEC-RAS, SITES, FLOW3D, and his experience in HEC-RAS extends to all components of one-dimensional and two-dimensional flow, steady-state and unsteady flow scenarios, as well as utilizing corresponding GIS applications for model development, consequence assessment, and map production. Applications of these modeling efforts consist of the evaluation of existing dams, analysis of proposed dam modifications, assessment of spillway performance, and design of new dams and reservoirs, as well as flood hazard mapping in large river environments.


Grady Hillhouse
Project Manager & Engineer
Freese & Nichols, Inc.

Grady Hillhouse is an engineer and project manager in Freese and Nichols’ Water Resources Design group specializing in heavy civil and waterway projects. He has served as project manager and design engineer on a wide variety of hydraulic structures including dam rehabilitations, outfall structures, and bank stabilizations. Grady’s expertise is in hydrologic and hydraulic analysis, including storm hydrology, 1D and 2D hydraulic modeling, dam breach analysis, 3D computational fluid dynamics, gate operation plans, and flood damage assessment. He is also experienced in the development of construction contract documents and construction oversight for dams, drainage, waterway, and other heavy civil projects.
