The Queen Charlotte Fault system is a segment of the North America - Pacific
plate boundary. From 45 Ma - 5 Ma, plate motion has been primarily translational.
Since 5 Ma, transpression has been the dominant mode of interaction. The plate
boundary west of the Queen Charlotte Islands is characterized...
Groundwater contamination on irrigated land is of concern in this nation
and around the world. In order to reduce the potential of groundwater
contamination by agricultural practices such as irrigation, fertilizer and pesticide
application, vadose-zone monitoring and sampling are needed. The main
objective of this study was to evaluate impacts...
A diagnostic modeling study of the cloud and precipitation
processes, and also frontogenesis have been analyzed in a severe
narrow cold-frontal rainband with the aid of a three-dimensional,
diagnostic cloud model.
The results of the model simulations indicate that the heavy
precipitation just behind the surface cold front was associated...
Assessment of the environmental impacts of an agricultural production system
requires information on both soil water quality and solute flux. Passive Capillary Samplers
(PCAPS), which sample water from the vadose zone using fiber glass wicks, have shown
potential to provide both flux and solute concentration in unsaturated zone sampling but...
Recent advances in computer technology have made possible the development of expert systems. Expert systems are computer programs that perform at the level of a human expert. Expert systems can help integrate and apply diverse sources of information and expertise to problems of integrated crop management. A prototype Crop Management...
The dynamical processes which maintain atmospheric disturbances
in regions of strong wintertime variability of the northern hemisphere
are examined using data from a GCM simulation. Time series of the
dependent variables and diabatic heating components from 10 Northern
Hemisphere winters simulated by the Oregon State University two-level
GCM are used....
