An initial attempt at diverting the river for irrigation purposes occurred in the late 1890s, when land speculator William Beatty built the Alamo Canal just north of the Mexican border the canal diPlanning and agreementsIn 1922, the Reclamation Service presented a report calling for the development of a dam on the Colorado River for flood control and electric power generation. The report was principally authored by Davis, and was called the FallDavis report after Interior Secretary Albert Fall. The FallDavis report cited use of the Design, preparation and contractingEven before Congress approved the Boulder Canyon Project, the Bureau of Reclamation was considering what kind of dam should be used. Officials eventually decided on a massive concrete archgravity dam, the design of which was overseen by the Bureaus chief design engineer John L. Savage.

Hoover Dam is solid concrete and it was designed specifically to be used as a dam, whereas, the Syncrude Tailings is the piled up dirt left over from mining operations. Although the material is compacted and otherwise treated to make a stable structure it relies on
NamingNamesBackgroundGeologyProductionConstructionRecordsIndustrySecuritySurveyors originally recommended the dam be constructed at Boulder Canyon, leading the initiative to be called the Boulder Canyon Dam Project. Even when Black Canyon later was deemed a better lo ion for the new structure, it continued to be referred to as the Boulder Dam. However, on September 17, 1930, at a ceremony in Nevada to mark the start of construction on a railroad line to the dam site, U.S. Secretary of the Interior Ray history.com: Elizabeth Nix
Contractors accidentally destroyed the plug holding water trapped inside the mine, which caused an overflow of the pond, spilling three million US gallons eleven thousand cubic metres of mine waste water and tailings, including heavy metals such as cadmium and lead, and other toxic elements, such as arsenic, beryllium, zinc, iron and copper into Cement Creek, a tributary of the Animas River and part of

2014/4/16 0183 32The Lingshan gold tailings dam was constructed using the upstream method. To ensure that the Lingshan tailings pond is safe in its current condition and during future operation, a stability analysis was necessary. In this study, the performance of the tailings material was analyzed based on such geotechnical parameters as the grain size distribution, cyclic triaxial strength, and undrained
