Wash load and bed-material load transport in the Yellow River
C.T. Yang, F.J.M. Simoes
2005, Journal of Hydraulic Engineering (131) 413-418
It has been the conventional assumption that wash load is supply limited and is only indirectly related to the hydraulics of a river. Hydraulic engineers also assumed that bed-material load concentration is independent of wash load concentration. This paper provides a detailed analysis of the Yellow River sediment transport data...

2005, Condor (107) 597-604
The rate of chick growth in high-latitude breeding shorebirds is rapid, but little is known about the effect of chick mass, growth, and brood movements on subsequent brood survival. To address these topics, we monitored chick growth patterns, daily brood movements, and survival of Western Sandpipers (Calidris mauri) on the...
Remotely triggered earthquakes following moderate mainshocks (or, why California is not falling into the ocean)
Susan E. Hough
2005, Seismological Research Letters (76) 58-66
On several occasions in recent memory California has experienced apparent clusters of earthquake activity that are too far apart to be considered related according to a classic taxonomy that includes foreshocks, mainshocks, and aftershocks. During a week-long period in July 1986, California experienced the M 6.0 North Palm Springs earthquake,...
