Dam Safety Programs: Difference between revisions

Revision as of 15:57, 25 July 2023

Dam safety is the art and science of ensuring the integrity and viability of dams such that they do not present unacceptable risks to the public, property, and the environment. It requires the collective application of engineering principles and experience, and a philosophy of risk management that recognizes that a dam is a structure whose safe function is not explicitly determined by its original design and construction. It also includes all actions taken to identify or predict deficiencies and consequences related to failure, and to document, publicize, and reduce, eliminate, or remediate to the extent reasonably possible, any unacceptable risks. FEMA 148 Glossary of Terms

The key entity that governs the many needed recurring (inspections) and one-time (dam repair) activities for one or hundreds of dams is the Dam Safety Program.

Dam safety programs are the entities responsible for assuring the safety of dams assigned to them are safe for continued operation. They protect property and people from the disastrous effects of avoidable dam failures and incidents and in establish emergency procedures for unforeseen circumstances.

The goals of a dam safety program include:

Preventing accidents and failures
Monitoring, inspecting, and surveilling dams on a frequent basis to detect emerging problems
Evaluating the safety and risks of each dam on a periodic basis
Avoiding safety issues and unacceptable risks when designing and constructing repairs to a dam
Protecting investments (provide for the continuing benefits of the dam(s)
Meeting legal obligations
Preparing for dam emergencies

Types of Dam Safety Programs

Some dam safety programs are owner dam safety programs, other dam safety programs are regulatory in nature and have the responsibility of assuring dam owners are keeping their dams safe. Owner dam safety programs keep dams safe through dam inspections, monitoring, risk/safety analysis, dam repair and emergency preparedness. Regulator dam safety programs perform ongoing oversight of dam owner dam safety programs to ensure the dams are safe, however the responsibility for the safety of the dam ultimately resides with the owner. In the Federal Government some agencies have dam safety programs which fulfill combined dam owner and regulator responsibilities.

Dam safety programs and the number and geographic extent of the dams assigned to them varies widely. Small owner dam safety programs include individuals, local governments, water companies, homeowner associations, recreational groups, special purpose districts and mining companies. Larger dam owners include governmental agencies (Federal or State), water supply companies, power generating utilities, and irrigation districts.

Proficiency requires for Dam Safety Programs

For a successful dam safety program there are many skills needed, including:

Knowledge of past dam failures and incidents
Development and application of laws, regulations, policies, and guidelines
Safety evaluation and risk assessment
Review of dam technical analyses, evaluation, and designs
Knowledge of dam safety technical areas including hydrology, geology, structural, hydraulics, geotechnical, and emergency management

This toolbox section is dedicated to sharing the key references, training, policies, and guidelines for having strong dam safety programs:

-As a result of several notable dam failures throughout the United States, the passage of the National Dam Inspection Act (PL 92-367) in 1972 started a major push to increase [[Public Safety|public safety]] by implementing a national dam inspection program for dams not owned by the federal government. “The activities performed under the program consisted of an inventory of dams; a [[survey]] of each State and Federal agency's capabilities, practices, and regulations regarding the design, [[construction]], [[operation]], and maintenance of dams; development of guidelines for inspection and evaluation of dam safety; and formulation of recommendations for a comprehensive national program”.<ref name="FEMA2004">[[Federal Guidelines for Dam Safety (FEMA P-93) | Federal Guidelines for Dam Safety (FEMA P-93), FEMA, 2004]]</ref>
