A dam failure or dam burst is a catastrophic type of structural failure characterized by the sudden, rapid, and uncontrolled release of impounded water or the likelihood of such an uncontrolled release.[1] Between the years 2000 and 2009 more than 200 notable dam failures happened worldwide.[2]

A dam is a barrier across flowing water that obstructs, that directs or slows down the flow, often creating a reservoir, lake or impoundments. Most dams have a section called a spillway or weir over or through which water flows, either intermittently or continuously, and some have hydroelectric power generation systems installed.

Dams are considered "installations containing dangerous forces" under international humanitarian law due to the massive impact of a possible destruction on the civilian population and the environment. Dam failures are comparatively rare, but can cause immense damage and loss of life when they occur. In 1975 the failure of the Banqiao Reservoir Dam and other dams in Henan Province, China caused more casualties than any other dam failure in history. The disaster killed an estimated 171,000 people[3] and 11 million people lost their homes.

Main causes of dam failures

[edit]
International special sign for works and installations containing dangerous forces

Common causes of dam failure include:

Deliberate breaching

[edit]

A notable case of deliberate dam breaching was the BritishRoyal Air ForceDambusters raid on Germany in World War II (codenamed "Operation Chastise"), in which six German dams were selected to be breached in order to impact German infrastructure and manufacturing and power capabilities deriving from the Ruhr and Eder rivers. This raid later became the basis for several films.

Attacks on dams were restricted in Article 56 of the 1977 Protocol I amendment to the Geneva Conventions. Dams may not be lawfully attacked "if such attack may cause the release of dangerous forces from the works or installations and consequent severe losses among the civilian population", unless "it is used for other than its normal function and in regular, significant and direct support of military operations and if such attack is the only feasible way to terminate such support". Similar provisions apply to other sources of "dangerous forces", such as nuclear power plants.[8]

Other cases include the Chinese bombing of multiple dams during Typhoon Nina (1975) in an attempt to drain them before their reservoirs overflowed. The typhoon produced what is now considered a 1-in-2,000-year flood, which few if any of these dams were designed to survive.

The Kakhovka Dam was destroyed in June 2023, during the Russian invasion of Ukraine.

Dam/incident Date Location Country Fatalities Details
Marib Dam575 ShebaYemen Un­known Unknown causes, possibly neglect. The consequent failure of the irrigation system provoked the migration of up to 50,000 people from Yemen.
Subiaco Dam1305 SubiacoItaly Un­known Amateur attempt to lower the dam
Döda fallet/1796 Ragunda lake burst disaster 1796 JämtlandSweden 0 Natural dam of glacial till had canal dug through it for purposes of navigation. As the till was hard to dig, water was used to erode the channel. The canal led to the failure of the dam.
Puentes Dam 1802 LorcaSpain 608 1,800 houses and 40,000 trees destroyed.[9]
Hogs Back Dam1829-04-03 OttawaUpper Canada Un­known Inexperience with cold weather engineering allowed for a small leak in wall to form on March 28 and the dam to slump on April 2. The following day, on April 3, the dam failed and washed away down the Rideau River. A new dam of a different design was built atop the foundation of the original later that same year.[10]
Bilberry reservoir1852-02-05 Holme ValleyUnited Kingdom 81 Failed in a heavy rain. Inquest found construction was culpably negligent.
Dale Dike Reservoir/Great Sheffield Flood1864-03-11 South YorkshireUnited Kingdom 244 Defective design and construction. Small leak in wall grew until new dam failed. More than 600 houses were damaged or destroyed. Led to regulation.
Iruka Lake Dam1868 Inuyama, Aichi Prefecture
(then Owari Province) 		Japan 941 Under the influence of heavy rain from late April, this soil dam collapsed on May 13.

Eight hundred and seven houses were destroyed, with another 11,709 flooded.
Mill River Dam 1874 Williamsburg, MassachusettsUnited States 139 Lax regulations and cost cutting led to an insufficient design, which fell apart when the reservoir was full. Six hundred million gallons of water were released, wiping out 4 towns and making national headlines. This dam break led to increased regulation of dam construction.
South Fork Dam/Johnstown flood1889-05-31 Johnstown, PennsylvaniaUnited States 2 208 Blamed on poor maintenance by owners, who lowered crest by a meter or more;[5] court deemed it an "Act of God". Followed exceptionally heavy rainfall. Sixteen hundred homes were destroyed.

Desná Dam1916 DesnáAustria-Hungary65 Construction flaws caused the dam failure.
Lower Otay Dam1916 San Diego County, CaliforniaUnited States 14 Over-topped from flooding following heavy rains. Locally, blame was placed on Charles Hatfield who had been contracted by the City of San Diego for his efforts in rainmaking. Court cases following the dam's failure resulted in neither liabilities being passed to Mr. Hatfield nor the original payment, as both of the court's decisions ruled the event 'an act of God'.
Sweetwater Dam1916-01-27 San Diego County, CaliforniaUnited States 0 Over-topped from flooding; spillway inadequate, water rose over a meter higher than the dam and waterfalled over its surface. Dam had been raised after a similar earlier overtopping. Partial failure.
