Abstract
A land-subsidence monitoring study was initiated in 1985 for the purpose of collecting data in Sacramento Valley, California, to document land-surface subsidence and to measure sediment compaction in response to ground-water pumping. Lithologic and geophysical logs obtained from the deeper of two boreholes drilled in 1987 near Woodland, California, are presented. The results of geotechnical and hydraulic laboratory tests on four sediment core samples extracted at 137, 151, 301, and 474 feet below land surface from a third borehole, drilled in 1990, are also reported. Construction of the extensometer well and the piezometer wells and equipment installed in the boreholes are described and illustrated. Data measured or recorded at the Woodland land- subsidence monitoring station from December 1987 through September 1992 are presented in tabular and graphic formats. These data include water levels from five piezometers, barometric pressure, and cumulative net sediment compaction.
