Summary

The U.S. Geological Survey, in cooperation with the Harris‐Galveston Subsidence District, City of Houston, and the Fort Bend Subsidence District, produced a dataset through 2018 of compaction values in the Chicot and Evangeline aquifers in the Houston‐Galveston region, Texas. This dataset contains compaction values of subsurface sediments (mostly in the fine-grained silt and clay layers because little compaction occurs in sand layers) in the Chicot and Evangeline aquifers that were recorded continuously by using analog technology at the 13 extensometers at 11 sites that were either activated or installed between 1973 and 1980. At 2 of the 11 sites, two extensometers are installed at different depths (one shallow and one deep). The [...]

Purpose

This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to scientific information regarding the cumulative compaction of subsurface sediments in Harris and Galveston Counties, Texas. Most of the land-surface subsidence in the Houston-Galveston region, Texas, occurs as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use, and irrigation that depressured and dewatered the Chicot and Evangeline aquifers, thereby causing compaction of the aquifer sediments, mostly in the fine-grained silt and clay layers.
