Preliminary investigation of land subsidence in the Sacramento Valley, California
B. E. Lofgren, R. L. Ireland
1973, Open-File Report 74-1064
Although a number of agencies have made leveling surveys in Sacramento Valley and a valleywide network of first- and second-order control exists, few areas have sufficient control for determining whether land subsidence has occurred and if so, how much, within the time span of vertical control. Available data suggest that...
