About: St. Francis Dam

An Entity of Type: infrastructure, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The St. Francis Dam was a concrete gravity dam located in San Francisquito Canyon in Los Angeles County, California, United States, built from 1924 to 1926 to serve Los Angeles's growing water needs. It catastrophically failed in 1928 due to a defective soil foundation and design flaws, triggering a flood that claimed the lives of at least 431 people. The collapse of the dam is considered to be one of the worst American civil engineering disasters of the 20th century and remains the second-greatest loss of life in California's history, after the 1906 San Francisco earthquake and fire.

  • Die St.-Francis-Talsperre war eine gekrümmte Gewichtsstaumauer aus Beton mit einem großen Stausee nahe bei Los Angeles in Kalifornien. Die Staumauer wurde von 1924 bis 1926 unter der Leitung von William Mulholland, einem Ingenieur des Los Angeles Department of Water and Power, gebaut. Die Staumauer brach wenige Minuten vor Mitternacht am 12. März 1928. Die entstehende Flutwelle tötete zwischen 550 und 600 Menschen. 2019 wurden dort ein Saint Francis Dam Disaster National Monument und ein Saint Francis Dam Disaster National Memorial ausgewiesen.

  • Le barrage de St. Francis était un barrage dont le réservoir alimentait l'aqueduc de Los Angeles en Californie. Il fut construit entre 1924 et 1926 à quelques kilomètres de l'actuelle ville de Santa Clarita. Lors de son premier remplissage, le 12 mars 1928, le barrage s'est effondré et a entrainé l'inondation du San Francisquito Canyon qui a couté la vie à près de 430 personnes. C'est la plus grave erreur de génie civil survenue aux États-Unis, et la deuxième plus grave catastrophe dans l'histoire de la Californie, après le séisme de 1906 à San Francisco. Elle couta sa carrière à l'ingénieur en chef du projet, William Mulholland. * Plan du réservoir. * Les vestiges du barrage en 2009. (fr)
  • The St. Francis Dam was a concrete gravity dam located in San Francisquito Canyon in Los Angeles County, California, United States, built from 1924 to 1926 to serve Los Angeles's growing water needs.

The collapse of the dam is considered to be one of the worst American civil engineering disasters of the 20th century and remains the second-greatest loss of life in California's history, after the 1906 San Francisco earthquake and fire. The St. Francis Dam was built to create a large regulating and storage reservoir that was an integral part of the Los Angeles Aqueduct. 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, California. The dam was designed and built between 1924 and 1926 by the Los Angeles Department of Water and Power, then named the Bureau of Water Works and Supply. The department was under the direction of its general manager and chief engineer, William Mulholland. The disaster effectively ended Mulholland's career. (en)
  • La diga St. Francis era una diga in calcestruzzo ad arco a gravità situata in California negli Stati Uniti d'America, che era stata progettata per creare un bacino idrico per la città di Los Angeles. Situata a 50 miglia (80 km) a nordovest di Los Angeles, la diga si trovava nei pressi di Santa Clarita. (it)
