Dam Safety

Supporting Dam Owners and Engineering Firms with Hydraulic and Structural Expertise

We combine our core strengths in hydraulics, hydraulic modeling, and structural engineering to help you identify the best solution for your dam safety concerns. We work with you to provide structural evaluation and engineering, condition assessments, field testing, and remedial design—in addition to computational fluid dynamics (CFD) and physical modeling to help inform your design. 

Our dam safety expertise and engineering experiences includes: 

  • Potential Failure Modes Analysis (PFMA)
  • Scour and stability analysis
  • Hydraulic gate inspections, condition assessments, and design for repair, rehabilitation or replacement
  • Dam and spillway inspections
  • Design of stability measures, including post-tensioned anchors
  • Total dissolved gas (TDG) abatement
  • Reporting to regulatory agencies (SEO, USACE, and FERC)
  • Physical, analytical, and computational fluid dynamics (CFD) modeling
  • Preparation of design reports, drawings, and specifications
  • Engineering services during construction
  • Updating FERC Supporting Technical Information (STI) documents

"I just finished reading through the final basis of design report for the Cabinet Gorge Spillway modifications project and I have one comment: JOB WELL DONE! The revisions made from the 90% version are excellent, especially in the sections of Dam Safety."
