Sensing the ups and downs of Las Vegas: InSAR reveals structural control of land subsidence and aquifer-system deformation Sensing the ups and downs of Las Vegas: InSAR reveals structural control of land subsidence and aquifer-system deformation
Land subsidence in Las Vegas, Nevada, United States, between April 1992 and December 1997 was measured using spaceborne interferometric synthetic aperture radar. The detailed deformation maps clearly show that the spatial extent of subsidence is controlled by geologic structures (faults) and sediment composition (clay thickness). The maximum detected subsidence during the 5.75 yr period...

Detection of aquifer system compaction and land subsidence using interferometric synthetic aperture radar, Antelope Valley, Mojave Desert, California Detection of aquifer system compaction and land subsidence using interferometric synthetic aperture radar, Antelope Valley, Mojave Desert, California
Interferometric synthetic aperture radar (InSAR) has great potential to detect and quantify land subsidence caused by aquifer system compaction. InSAR maps with high spatial detail and resolution of range displacement (±10 mm in change of land surface elevation) were developed for a groundwater basin (∼103 km2) in Antelope Valley, California, using radar data collected from the ERS-1...

Hydrologic effects associated with the January 17, 1994 Northridge, California, earthquake Hydrologic effects associated with the January 17, 1994 Northridge, California, earthquake
This report compiles hydrologic observations in southern California associated with the 1994 Mw = 6.7 Northridge, California earthquake. In southern California, the largest ground water level change was a drop of 52 cm at Crystalaire. Most of the steplike water-level changes recorded following the Northridge earthquake agreed in direction with the sign of the calculated coseismic volume...

Land subsidence, the loss of surface elevation as a result of the removal of subsurface support, affects every state in the United States. More than 17,000 mi2 of land in the United States has been lowered by the various processes that produce land subsidence with annual costs from resulting flooding and structural damage that exceed $125 million. It is estimated that an additional $400...

Technique for predicting ground-water discharge to surface coal mines and resulting changes in head Technique for predicting ground-water discharge to surface coal mines and resulting changes in head
Changes in seepage flux and head (groundwater level) from groundwater drainage into a surface coal mine can be predicted by a technique that considers drainage from the unsaturated zone. The user applies site-specific data to precalculated head and seepage-flux profiles. Groundwater flow through hypothetical aquifer cross sections was simulated using the U.S. Geological Survey finite...

PREDICTING GROUND-WATER DRAINAGE TO SURFACE MINES. PREDICTING GROUND-WATER DRAINAGE TO SURFACE MINES.
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless distance, and dimensionless seepage flux as a function of dimensionless time are developed from results of the numerical modeling. Changes in seepage flux and ground-water levels can be estimated from...
