Oct. 29, 2002 — The Federal Energy Regulatory Commission (FERC) has finalized and issued a revised chapter of its Engineering Guidelines for the Evaluation of Hydropower Projects.
The engineering guidelines provide guidance on conducting engineering investigations and analysis at FERC-licensed projects.
Chapter III, “Gravity Dams,” has been updated to include several advances in the analysis of concrete gravity dams.
The significant changes include the following:
“- Changed safety factors when strength parameter uncertainty is reduced;
“- Additional guidance on uplift pressure;
“- Revised procedures for earthquake analysis;
“- Methods for dealing with hydrodynamic forces; and
“- Guidance on computer modeling.
The revised Chapter III, as well as the rest of FERC’s Engineering Guidelines, are on the Commission’s web site at http://www.ferc.gov/hydro/docs/engguide/guidelines.htm.
