Empirical model for the volume-change behavior of debris flows Empirical model for the volume-change behavior of debris flows
The potential travel down hillsides; movement stops where the volume-change behavior of flows as they travel down hillsides ; movement stops where the volume of actively flowing debris becomes negligible. The average change in volume over distance for 26 recent debris flows in the Honolulu area was assumed to be a function of the slope over which the debris flow traveled, the degree of...

Empirical prediction of strong ground motion Empirical prediction of strong ground motion
In 1982, we published equations for the prediction of various measures of ground motion as a function of earthquake magnitude, distance from the earthquake rupture, and site geology. Many more strong-motion recordings have been obtained since we published our equations. The predictions of the ground motions from our published equations are in reasonable agreement with the peak...

Estimating bridge scour in New York from historical U.S. geological survey streamflow measurements Estimating bridge scour in New York from historical U.S. geological survey streamflow measurements
Historical streamflow measurements by the U.S. Geological Survey an bridge-inspection reports by the New York State Department of Transportation are being used to estimate scour at 31 bridges in New York State. Streamflow measurements that were made before, during, or after high flows are used to estimate scour and to define hydraulic properties associated with floods. Clear-water scour...

Estimation of water-filled and air-filled porosity in the unsaturated zone, Yucca Mountain, Nevada Estimation of water-filled and air-filled porosity in the unsaturated zone, Yucca Mountain, Nevada
The responses of density and dielectric logs are formulated in terms if the matrix properties, air-filled porosity and water-filled porosity. Porosity values obtained from logs from borehole USW G-2 are in reasonable agreement with estimates from core determinations.

Evaluation of historical scour at selected stream crossings in Indian Evaluation of historical scour at selected stream crossings in Indian
Geophysical data were collected by means of ground-penetrating radar and tuned transducer systems to estimate the historical scour at ten bridges in Indiana. These geophysical data were used to compare and evaluate the results of 13 published pier-scour equations. In order to make this comparison, it was assumed that the measured historical scour was associated with the peak historical...

Evaluation of the extent of contaminated sediments in the west branch of the Grand Calumet river, Indiana-Illinois, USA Evaluation of the extent of contaminated sediments in the west branch of the Grand Calumet river, Indiana-Illinois, USA
The extent of contamination in river sediments is often not rigorously evaluated. In many cases, only surface sediment samples are taken. In other cases, entire sediment cores are composited for analysis, an approach that limits the ability to identify discrete zones of contamination. In addition, few studies include information on the rate of sedimentation. Composited sediment cores...

Finite-difference model for 3-D flow in bays and estuaries Finite-difference model for 3-D flow in bays and estuaries
This paper describes a semi-implicit finite-difference model for the numerical solution of three-dimensional flow in bays and estuaries. The model treats the gravity wave and vertical diffusion terms in the governing equations implicitly, and other terms explicitly. The model achieves essentially second-order accurate and stable solutions in strongly nonlinear problems by using a three...

Flood elevation limits in the rocky mountains Flood elevation limits in the rocky mountains
An analysis of 77,987 station-years of streamflow-gaging station data from 3,748 stations in the Rocky Mountains indicates that there is a latitude-dependent elevation limit to substantial rainfall-produced flooding. The elevation limit ranges from about 1,650 m in Montana to about 2,350 m in New Mexico. Above this elevation limit, large rainfall-produced floods occur very infrequently...
