st francis dam ethical issues

[54], Although they were not unanimous on all points, most commissions quickly reached their respective conclusions. He felt that there should be a reservoir of sufficient size to provide water for Los Angeles for an extended period in the event of a drought or if the aqueduct were damaged by an earthquake. In the area where the dam would later be situated, he found the mid and upper portion of the western hillside consisted mainly of a reddish colored conglomerate and sandstone formation that had small strings of gypsum interspersed within it.

There were others, such as the railroad commission and several political entities who only sent investigators or representatives. On May 12 th, 1928, the St. Francis Dam broke. This height increase ... Ethical_Issues_St._Francis_Dam.pdf Author: Kelly The St. Francis Dam Failure. [4], In the early years of Los Angeles, the city's water supply was obtained from the Los Angeles River. Here a ladder had become wedged in a crack that had opened apparently during this rocking or tilting process and then had become tightly pinched in place as the section settled back on its foundation. At 11:57 p.m. on March 12, 1928, the dam catastrophically failed, and the resulting flood killed at least 431 people. This webinar will examine the ethical issues that arose from the 1928 failure of the St. Francis Dam near Los Angeles, California. [63], Although this investigation was insightful and informative, the theory, along with others which hypothesized an appreciably increasing amount of seepage just prior to the failure, becomes less likely when it is compared against the eyewitness accounts of the conditions in the canyon and near the dam during the last thirty minutes before its collapse. Furthermore, the two cracks, which bordered each side of the standing center section, would have served as hinges to prevent this. [13] This unexpectedly rapid growth brought a demand for a larger water supply. [51], The flood entered the Santa Clarita valley at 12 mph (19 km/h). Due for the most part to inadequate drainage of the base and side abutments, the phenomenon of uplift destabilizes gravity dams by reducing the structure's "effective weight", making it less able to resist horizontal water pressure. wz(��,�˕�����Y���� [xt�p���t�`� [68], The center section, which had become known as "The Tombstone" due to a newspaper reporter's description of it as such, became an attraction for tourists and souvenir hunters. This scenario, having its roots in the works of Willis and Grunsky, was expanded upon by the author Charles Outland in his book Man-Made Disaster : The Story of St. Francis Dam which was first published in 1963. Most of the design profiles and computation figures of stress factors for the St. Francis came from this adaptation of the plans and formulas which had been used in the constructing of Mulholland Dam.

There then "quickly followed ... the collapse of large sections of the dam. The largest fragments fell across the lower portion of the standing section, coming to rest partially on its upstream face. The St. Francis, sometimes referred to as the San Francisquito, was only the second concrete dam to be designed and built by the Bureau of Water Works and Supply. The ruins and the scar from the ancient landslide can be seen from San Francisquito Canyon Road. Measurements taken proved the crack must have been much wider at the time that the ladder entered it. Francis.

The official death toll in August 1928 was 385, but the remains of victims continued to be discovered every few years until the mid-1950s. 0000086427 00000 n The committee ended their report with, "...having examined all the evidence which it has been able to obtain to date reports its conclusions as follows: The consensus of most of the investigating commissions was that the initial break had taken place at or near the fault line on the western abutment, which had been a problem area since water first covered the area. Learn about soil conditions at the site that should have been investigated and accommodated in the design.

Certain design deficiencies were uncovered in the plans made by the engineering department during the planning phase of the dam.

On May 12 th, 1928, the St. Francis Dam broke. He stated the reservoir would now have a capacity of 38,000 acre-feet (47,000,000 m3) and that the dam's height would be 185 feet (56 m) above stream bed level.
