Database of historical levee breaks in the California Central Valley, particularly in the Sacramento-San Joaquin Delta. Dataset was built over years based on a variety of sources and ongoing incidents during the period in which the dataset steward was in the Delta Levees Program. Consequently, it primarily consists of levee failures in the Delta, plus additional levee failures mapped by the State Office of Emergency Services for the 1983, 1986, 1995, and 1997 floods throughout the Central Valley. It is useful to know where historic breaks occurred for ongoing purposes requiring geotechnical and engineering information. |
