The Forest and Rangeland Renewable Resources Planning Act of 1974 requires the U.S. Forest Service to periodically evaluate the U.S. timber situation. An important part of such studies is the determination of forest product imports from Canada through evaluation of Canadian log and product supply conditions. Other studies have projected...
The objective of this study was to measure the consequences of alternative
forest management intensification programs. These consequences
include future harvest levels, silvicultural labor and capital
requirements, and the income and employment generated directly and indirectly.
The system utilizes the Timber Resource Economic Estimation
System (TREES) model, a harvest scheduling...
The purpose of this research was to develop methods for using geographic information system (GIS) analysis and unsupervised classification of Global Vegetation Index (GVI) images to improve carbon budget estimates of the former Soviet Union (FSU). A GIS was used to locate the geographic distribution and estimate the area of...
Streamflow variability can provide valuable information for nonpoint source
pollution monitoring program planning. The research papers presented in this thesis
examine selected properties of streamflow variability in Oregon to advance its application
in regional planning of water quality monitoring programs. The products of this research
depict Oregon streams by their...
Agricultural land conversion is a complex process that involves a
matrix of decisions and decision-makers. This study examines the
nature and relative significance of spatial factors that influence the
decisions of farmers who either sell farmland to developers for urban
use or retain it for agricultural use. The conceptual model...
Bankfull discharge is an important indicator of streamfiow and affects
physical instream habitat. Geographic Information Systems (G IS), hydrologic
modeling, and statistical analysis were utilized to assess the relationship of
bankfull discharge recurrence intervals and land use / land cover watershed
wide and for stream adjacent buffers and bands of...
Water right marketing and transfers represent a resource reallocation
strategy that has received considerable attention in the American West owing to
nearly full appropriation of water in the region. Several western states permit
transfers between different uses and places of use thus allowing water to move to
higher-value economic activities....
Stream management and design recommendations related to the Salmon Habitat Recovery Program in the Pacific Northwest require area specific information concerning appropriate methods of stream classification, bankfull discharge recurrence intervals, and hydraulic geometry relationships. New region specific information, based on field measurements, is presented here. The Rosgen Classification of Natural...
A numerical model for the simulation of fully-coupled fluid-structure
interaction is developed in this study. In modeling the fluid, the Reynolds
Averaged Navier-Stokes equations are solved for an incompressible viscous
fluid field and a k-ε model is employed for turbulence computations.
Hydrodynamic forces obtained by the integration of the fluid...
