Gravity Arch Dam

This Dam is located in the Sierra Nevada Mountains and is a Jorgensen type, constant angle, variable radius , concrete arch dam with a crest length approximately 137 metres and a height at the center of 36.5 metres . A protective membrane was installed on the upstream face in 1997. As part of an overall study of Dam, STRAAM conducted a dynamic investigation during October 2010. The objective of this investigation was to ascertain the dynamic properties of the dam and to assist with the validation of a mathematical model of the structure and used to compare with future measurements .
