Konstantine P. Georgakakos, Diane E. Smith
2000, Open-File Report 2000-335
A monthly snow-pack and soil- moisture accounting model is formulated for application to each of the climate divisions of the conterminous United States for use in climate impacts-assessment studies. Statistical downscaling and bias-adjustment components complement the model for the assimilation of large-scale global climate model data. Simulations of the formulated...

Preliminary estimate of the amplification of possible earthquake ground motion at a site in Charleston County, South Carolina
Russell L. Wheeler, Chris H. Cramer
2000, Open-File Report 2000-484
We estimate site amplification at the location of a proposed bridge near Charleston, South Carolina. Model calculations indicate that amplification at periods of 1 s and longer is likely to be strongly influenced by the effects of a large contrast in shear-wave velocity at a depth of approximately 1 km (3,000 ft). On-site...
