Originating in the Bayan Har Mountains in Qinghai province of Western China, it flows through nine provinces, and it empties into the Bohai Sea near the city of Dongying in Shandong province. The Yellow River basin has an east–west extent of about 1,900 kilometers (1,180 mi) and a north–south extent of about 1,100 km (680 mi).

The St. Francis Dam was a curved concrete gravity dam, built to create a large regulating and storage reservoir for the city of Los Angeles, California. The reservoir was an integral part of the city's Los Angeles Aqueduct water supply infrastructure. It was located in San Francisquito Canyon of the Sierra Pelona Mountains, about 40 miles (64 km) northwest of downtown Los Angeles, and approximately 10 miles (16 km) north of the present day city of Santa Clarita.
William Mulholland was a self-taught Irish American civil engineer who was responsible for building the infrastructure to provide a water supply that allowed Los Angeles to grow into the largest city in California. As the head of a predecessor to the Los Angeles Department of Water and Power, Mulholland designed and supervised the building of the Los Angeles Aqueduct, a 233-mile (375 km)-long system to move water from Owens Valley to the San Fernando Valley. The creation and operation of the aqueduct led to the disputes known as the California Water Wars. In March 1928, Mulholland's career came to an end when the St. Francis Dam failed just over 12 hours after he and his assistant gave it a safety inspection.
The Johnstown Flood occurred on Friday, May 31, 1889, after the catastrophic failure of the South Fork Dam, located on the south fork of the Little Conemaugh River, 14 miles (23 km) upstream of the town of Johnstown, Pennsylvania. The dam broke after several days of extremely heavy rainfall, releasing 14.55 million cubic meters of water. With a volumetric flow rate that temporarily equaled the average flow rate of the Mississippi River, the flood killed more than 2,200 people and accounted for $17 million of damage.
The Banqiao Reservoir Dam is a dam on the River Ru (汝河), a tributary of the Hong River in Zhumadian City, Henan province, China. The Banqiao dam and Shimantan Reservoir Dam are among 62 dams in Zhumadian that failed catastrophically in 1975 during Typhoon Nina. The dam was subsequently rebuilt.

The Dnieper River system of dams was created to prevent uncontrolled flooding and improve water transportation infrastructure. Coordination and operation of all dams on Dnieper is conducted by government company Ukrhydroenerho. The system of dams is also known as Dnieper Cascade of HES. In 1970, the Kyiv dam partially prevented flooding in comparison with the 1931 Kyiv flooding.
The Machchhu dam failure or Morbi disaster was a dam-related flood disaster which occurred on 11 August 1979, in India. The Machchu-2 dam, situated on the Machchhu river, burst, sending a wall of water through the town of Morbi of Gujarat, India. Estimates of the number of people killed vary greatly ranging from 1800 to 25000 people.

The Mariana dam disaster, also known as the Bento Rodrigues or Samarco dam disaster, occurred on 5 November 2015, when the Fundão tailings dam at the Germano iron ore mine of the Samarco Mariana Mining Complex near Mariana, Minas Gerais, Brazil, suffered a catastrophic failure, resulting in flooding that devastated the downstream villages of Bento Rodrigues and Paracatu de Baixo, killing 19 people. The extent of the damage caused by the tailings dam collapse is the largest ever recorded with pollutants spread along 668 kilometres (415 mi) of watercourses.
The Brumadinho dam disaster occurred on 25 January 2019 when Dam I, a tailings dam at the Córrego do Feijão iron ore mine, 9 kilometres (5.6 mi) east of Brumadinho, Minas Gerais, Brazil, suffered a catastrophic failure. The dam is owned by Vale, the same company that was involved in the 2015 Mariana dam disaster. The dam released a mudflow that advanced through the mine's offices, including a cafeteria during lunchtime, along with houses, farms, inns and roads downstream. 270 people died as a result of the collapse, of whom 259 were officially confirmed dead, in January 2019, and 11 others reported as missing, whose bodies had not been found.
The 1975 Banqiao Dam failure was the collapse of 62 dams, including the Banqiao Dam, in Henan, China in August 1975 under the influence of Typhoon Nina. The dam failure created the third-deadliest flood in history which affected a total population of 10.15 million and inundated around 30 cities and counties of 12,000 square kilometers, with an estimated death toll ranging from 85,600 to 240,000. The flood also caused the collapse of 6.8 million houses. The dam failure took place during the Cultural Revolution when most people were busy with the "revolution"; the Chinese Communist Party (CCP) as well as the Chinese government subsequently hid the details of the disaster until the 1990s, when The Great Floods in China's History (中国历史大洪水), a book prefaced by Qian Zhengying who served as the Minister of Water Resources of China in the 1970s and 1980s, revealed details of the event to the public for the first time.
