Abstract:

Present studies by the U. S. Bureau of Reclamation in California indicate that under certain geologic conditions similar subsidence can also be caused by rising ground-water levels, which creates a flotation condition; and periodic fluctuation (lowering and complete recovery) of ground-water levels without an actual decline. Both types of subsidence may be present in California's Central Valley. The possibilities of subsidence generated by these conditions should be considered in the planning and design of all water developments.
