Many wide-ranging mammal species have experienced significant declines over the last 200 years; restoring these species will require long-term, large-scale recovery efforts. We highlight 5 attributes of a recent range-wide vision-setting exercise for ecological recovery of the North American bison (Bison bison) that are broadly applicable to other species and...
Viscoelastic love-type surface waves
Roger D. Borcherdt
2008, Conference Paper, The 14th World Conference on Earthquake Engineering
The general theoretical solution for Love-Type surface waves in viscoelastic media provides theoreticalexpressions for the physical characteristics of the waves in elastic as well as anelastic media with arbitraryamounts of intrinsic damping. The general solution yields dispersion and absorption-coefficient curves for the waves as a function of frequency and theamount...

Sediment and ancillary data are fundamental requirements for the...
Estimating sediment discharge: Appendix D
John R. Gray, Francisco J. M. Simões
2008, Book chapter, Sedimentation engineering: processes, measurements, modeling, and practice
Sediment-discharge measurements usually are available on a discrete or periodic basis. However, estimates of sediment transport often are needed for unmeasured periods, such as when daily or annual sediment-discharge values are sought, or when estimates of transport rates for unmeasured or hypothetical flows are required. Selected methods for estimating suspended-sediment,...
