BSE engineers have extensive experience in the full range of hydrologic and hydraulic analyses associated with dam safety evaluations and designs, including:

​

• Hydrologic analyses for Probable Maximum Floods (PMFs) and other extreme flood events related to dam safety evaluations, utilizing the appropriate precipitation depth data including NOAA Atlas and Hydrometeorological Reports (HMRs) or other approved federal, state, or local specific procedures for recurrence interval or Probable Maximum Precipitation (PMP) on high hazard dams.

• Reservoir routings and evacuation analyses to size spillways, outlet works, and other hydraulic structures such as energy dissipators, stilling basins, and erosion protection measures. 

• Minimum freeboard analyses using a flood stage hydrograph and probabilistic wind data or wind atlas data have been prepared.

• The design of hydraulic structures for new dams and rehabilitation for existing dams, including preparation of drawings and specifications.
