There are currently over 90,000 dams in the United States National Inventory of Dams (NID), with 76% of these having a High Hazard Potential classification and and average age of 60 years.[1] As a result of the high consequences that accompany the failure of any High Hazard Potential dam, the rehabilitation of these aging structures becomes increasingly necessary.
The planning and rehabilitation design of an existing dam requires many different tasks involving a variety of disciplines. Common tasks include but are not limited to:
- Legal Agreements
- Permitting
- Public Outreach
- Hazard Potential Classification (including consideration of hazard creep)
- Water Demand / Population Studies
- Benefit-Cost Analyses
- Hydrologic Studies
- Environmental Impact Studies
- Geologic and Geotechnical Investigations
- Seismic Investigations
- Structural / Embankment Design
- Hydraulic Design
- Risk Communication
- Construction Management
