- (a) The owner shall use the U.S. Army Corps of Engineers’ Hydrologic Engineering Center River Analysis System (HEC-RAS), version 6.3.1, available as noted in Appendix B, for dam breach analysis modeling.
- (b) An owner wishing to use other techniques for breach modeling shall submit a written request for approval of the technique to the department for each particular site prior to using the technique. The request shall contain a description of the technique, including how the technique addresses the parameters addressed by the techniques identified in (a), above.
- (c) If the department determines that the technique can be correctly applied to the hydrologic and topographic conditions of the dam and downstream area, within the limitations and capabilities of the modeling technique, and that it will provide the detailed information required by these rules, the department shall approve the technique for use on that site and shall so notify the owner in writing.
