Rheological analysis of fine-grained natural debris-flow material Rheological analysis of fine-grained natural debris-flow material
Experiments were conducted on large samples of fine-grained material (???2mm) from a natural debris flow using a wide-gap concentric-cylinder viscometer. The rheological behavior of this material is compatible with a Bingham model at shear rates in excess of 5 sec. At lesser shear rates, rheological behavior of the material deviates from the Bingham model, and when sand concentration of...

Summit Lake landslide and geomorphic history of Summit Lake basin, northwestern Nevada Summit Lake landslide and geomorphic history of Summit Lake basin, northwestern Nevada
The Summit Lake landslide, northwestern Nevada, composed of Early Miocene pyroclastic debris, Ashdown Tuff, and basalt and rhyolite of the Black Rock Range, blocked the upper Soldier Creek-Snow Creek drainage and impounded Summit Lake sometimes prior to 7840 yr B.P. The slide covers 8.2 km2 and has geomorphic features characteristic of long run-out landslides, such as lobate form...

A numerical study of some potential sources of error in side-by-side seismometer evaluations A numerical study of some potential sources of error in side-by-side seismometer evaluations
This report presents the results of a series of computer simulations of potential errors in test data, which might be obtained when conducting side-by-side comparisons of seismometers. These results can be used as guides in estimating potential sources and magnitudes of errors one might expect when analyzing real test data. First, the derivation of a direct method for calculating the...
