Serial Information: Journal of the Soil Mechanics and Foundations Division, 1967, Vol. 93, Issue 3, Pg. 23-36

Document Type: Journal Paper


A report is presented on the investigation of more than 1,000 existing dams in California. Deficiencies at over 100 reservoirs are examined and remedial measures are investigated. Many defects in old dams are attributed either to adverse geological conditions or outmoded engineering practices, often combined with poor maintenance. The strengths and weaknesses of various types of dams are compared. Seismology and geology in California are considered in relation to construction and maintenance of dams and reservoirs. Problems in spillways and outlets and in reservoir margins are described. The requirements for programs to safeguard dams are examined.
