Michelle Sneed is a hydrologist with the U.S. Geological Survey and has been with the California Water Science Center since 1994. She has published many studies of land subsidence related to fluid-pressure changes in areas throughout California and other areas in the Western U.S. She integrates various methods of land-surface elevation (and elevation change) measurement, including spirit leveling, Global Positioning System, extensometry, and Interferometric Synthetic Aperture Radar (InSAR) techniques, to leverage the diverse spatial and temporal scales of the datasets. Analyses and simulations have focused on the preconsolidation stress, vertical hydraulic conductivities, and the elastic and inelastic compressibilities (storage) of aquifer-system components based on hydrogeological structure, land-surface elevation changes, and groundwater-level changes. Recent studies in the San Joaquin and Coachella Valleys explore the impact of subsidence on water-conveyance infrastructure.
