Increasing water demand for growing municipalities, for water-based recreation
and for fishery and wildlife habitat has intensified pressure on the existing resource. Reallocation of water from existing uses to other, higher-valued uses is receiving greater attention due to constraints on development of new water supplies. A key to reallocation is...
Everyone involved in online education talks about community – what is it, how is it created, do students really want it? Most researchers now agree that online education is enhanced through a greater sense of community within the online classroom; however, the factors that make for a substantive and quality...
I examined the relative roles of biotic and abiotic factors in structuring redband trout
Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the
relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...
The overall goal of this study was to identify multiple scales of habitat use and habitat electivity by redband/steelhead trout and define the limiting factors affecting the distribution patterns of this species during summer flows.
The main objective in chapter 2 was to identify the most important habitat associations that...
Water temperature in rivers and streams is an important factor for aquatic ecosystem health. Measurement of stream temperature has traditionally been accomplished by point temperature measurements, continuous point temperature loggers, and more recently, airborne remote sensing techniques such as Forward-Looking Infrared Radar (FLIR) or Thermal Infrared Radiometry. While each of...
Creative nonfiction is a genre replete with contradictions--the name itself shows that: nonfiction writing is true and factual, but creative writing is imaginative and inventive. Because of fundamental contradictions like this, there is no standardized or even most common definition of the genre. This creates confusion for both critics and...
Two numerical methods are presented that can be used to solve
second order nonlinear ordinary differential equations with periodic
boundary conditions. One of these methods is a shooting method developed
solely for the periodic problem. The other, "quasilinearization,"
is a method applicable to a wide variety of problems. It is...
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...
Land management practices in much of the western US that included wildland fire suppression have led to greater fuel loads than has been typical of historical fire regimes. In response to the increased wildland fire risk, “restoration” has emerged as a forest management goal. Restoration involves removal of uncharacteristic amounts...
The equations of motion of an elastic cable suspended in a
viscous medium from two arbitrary points are derived. These are
then linearized for the undamped, inextensible case, and it is found
that the equations describing the in-plane motion of the cable are
then independent of the equation describing the...
