1997, Open-File Report 97-811
The water resources of the Albuquerque metropolitan area are under increasing scrutiny by Federal and State regulators. Because of a lack of available low-flow data for use in addressing potential water-quality problems, a project was established to collect low-flow water-quality and discharge data. The project was initiated under a current...

Claudia C. Faunt
1997, Water-Resources Investigations Report 95-4132
This study characterizes the hydrogeologic system of the Death Valley region, an area covering approximately 100,000 square kilometers. The study also characterizes the effects of faults on ground-water movement in the Death Valley region by synthesizing crustal stress, fracture mechanics, and structural geologic data. The geologic conditions are typical of...
Dynamic deformations and the M6.7, Northridge, California earthquake
Joan S. Gomberg
1997, Soil Dynamics and Earthquake Engineering (16) 471-494
A method of estimating the complete time-varying dynamic formation field from commonly available three-component single station seismic data has been developed and applied to study the relationship between dynamic deformation and ground failures and structural damage using observations from the 1994 Northridge, California earthquake. Estimates from throughout the epicentral region...

1997, Open-File Report 97-425
Record flooding occurred on many streams in northern Ilinois during July 18-20, 1996. Over 16 inches of rain fell at some locations during and just prior to this period. Peak of record discharges were recorded at 19 U.S. Geological Survey (USGS) streamflow-gaging stations. The USGS, in cooperation with the Illinois...
