Geotechnical properties of debris-flow sediments and slurries Geotechnical properties of debris-flow sediments and slurries
Measurements of geotechnical properties of various poorly sorted debris-flow sediments and slurries (??? 32 mm diameter) emphasize their granular nature, and reveal that properties of slurries can differ significantly from those of compacted sediments. Measurements show that: (1) cohesion probably offers little resistance to shear in most debris flows under low confining stresses...

Hydraulic modeling of unsteady debris-flow surges with solid-fluid interactions Hydraulic modeling of unsteady debris-flow surges with solid-fluid interactions
Interactions of solid and fluid constituents produce the unique style of motion that typifies debris flows. To simulate this motion, a new hydraulic model represents debris flows as deforming masses of granular solids variably liquefied by viscous pore fluid. The momentum equation of the model describes how internal and boundary forces change as coarse-grained surge heads dominated by...

Immunization with viral antigens: Infectious haematopoietic necrosis Immunization with viral antigens: Infectious haematopoietic necrosis
Infectious haematopoietic necrosis (IHN) is one of the most important viral diseases of salmonids, especially among juvenile fish where losses can be high. For over 20 years, researchers have tested a variety of preparations for control of IHN. Early vaccines consisted of killed virus and were effective when delivered by injection, but too costly to be practical on a large scale...

Impact of an extreme event on the sediment budget: Hurricane Andrew in the Louisiana barrier islands Impact of an extreme event on the sediment budget: Hurricane Andrew in the Louisiana barrier islands
This paper examines the influence of Hurricane Andrew on the sediment budget of an 80-kilometer section of the Louisiana barrier islands west of the modern Mississippi delta. Because long-term bathymetric change has been extensively studied in this area, excellent baseline data are available for evaluating the impact of Hurricane Andrew. Results show that despite the high intensity of...

In-situ stress and fracture permeability in a fault-hosted geothermal reservoir at Dixie Valley, Nevada In-situ stress and fracture permeability in a fault-hosted geothermal reservoir at Dixie Valley, Nevada
As part of a study relating fractured rock hydrology to in-situ stress and recent deformation within the Dixie Valley Geothermal Field, borehole televiewer logging and hydraulic fracturing stress measurements were conducted in a 2.7-km-deep geothermal production well (73B-7) drilled into the Stillwater fault zone. Borehole televiewer logs from well 73B-7 show numerous drilling-induced...

Lignin phenols in sediments of Lake Baikal, Siberia: Application to paleoenvironmental studies Lignin phenols in sediments of Lake Baikal, Siberia: Application to paleoenvironmental studies
Sediments from three cores obtained from distinct depositional environments in Lake Baikal, Siberia were analyzed for organic carbon, total nitrogen and lignin phenol concentration and composition. Results were used to examine changes in paleoenvironmental conditions during climatic cycles of the late Quaternary ( 125 ka). Average organic carbon, and total nitrogen concentrations, atomic...

Long time-series of turbid coastal water using AVHRR: An example from Florida Bay, USA Long time-series of turbid coastal water using AVHRR: An example from Florida Bay, USA
The AVHRR can provide information on the reflectance of turbid case II water, permitting examination of large estuaries and plumes from major rivers. The AVHRR has been onboard several NOAA satellites, with afternoon overpasses since 1981, offering a long time-series to examine changes in coastal water. We are using AVHRR data starting in December 1989, to examine water clarity in...
