Forest biomass estimation with hemispherical photography for multiple forest types and various atmospheric conditions

Creator:: Clark, Joshua Andrew
Abstract:: The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...

Landscape Inventory and Harvest Strategies for Individual Western Juniper in Eastern Oregon

Creator:: Schriver, Robert
Abstract:: Western juniper is a native species in eastern Oregon that became invasive during the last century since its range increased fivefold from 1936 to 1988. Western juniper’s ability to absorb rainfall and groundwater has deleterious effects on stream flow and sensitive sage grouse habitat in eastern Oregon. New methods of...

Effect of constituent materials and curing methods on the abrasion resistance and durability of high performance concrete for pre-cast pre-stressed bridge deck slabs

Creator:: Keshari, Shweta
Abstract:: This thesis is the consequence of a research effort undertaken by the School of Civil and Construction Engineering at Oregon State University and funded by the Oregon Department of Transportation (ODOT) and the Federal Highway Administration (FHWA). The principal objective of the effort was to reduce the life cycle cost...

Environmental durability of reinforced concrete deck girders strengthened with surface-bonded carbon fiber-reinforced polymer

Creator:: Sopal, Gautam Jayant
Abstract:: Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged environmental exposure and combined...

Developing tools to improve tsunami resilient design of coastal structures

Creator:: Thomas, Seth Alan
Abstract:: Over the last decade the world has seen three major tsunamis strike the coasts of Indonesia, Samoa, and Chile. These tsunamis have caused significant losses of life and property on the coastal cities of these and nearby countries. The NEES (Network for Earthquake Engineering Simulation) Housesmash project was created to...

Aerial forest operations : mineral amendment project

Creator:: Cornell, Jennie L.
Abstract:: A helicopter operations problem was studied for a private forest landowner testing an experimental application of minerals on Douglas-fir (Pseudotsuga menziesil) in the Coast Range of Oregon to offset growth reductions from Swiss needle cast disease. A planning approach was needed to minimize costs for transportation and aerial application of...

Assessment of Airborne Light Detection and Ranging (LiDAR) for use in common forest engineering geomatic applications

Creator:: Craven, Michael B.
Abstract:: Airborne Light Detection and Ranging (LiDAR) has become a popular remote sensing technology to create digital terrain models and provide forest inventory information. However, little research has been done to investigate the accuracy of using airborne LiDAR to perform measurement tasks common to Forest Engineering. This thesis contains two manuscripts...

Accuracy assessment of LiDAR point cloud geo-referencing

Creator:: Williams, Keith E.
Abstract:: Three-dimensional laser scanning has revolutionized spatial data acquisition and can be completed from a variety of platforms including airborne (ALS), mobile (MLS), and static terrestrial (TLS) laser scanning. MLS is a rapidly evolving technology that provides increases in efficiency and safety over static TLS, while still providing similar levels of...

Thinning aged Douglas-fir : an analysis of mobilization costs and a log bucking strategy for revenue improvement

Creator:: Pilkerton, Stephen J.
Abstract:: Contract harvest operations have become the preferred approach to reducing the largest cost component of timber production through free market competition amongst logging contractors bidding or negotiating for work. The goal of this research was to investigate economic components of harvesting operations not previously studied for steep slope thinning harvests...

Snow Grain Evolution in Forested and Open Regions – Implications for Remote Sensing

Creator:: Weiss, Sydney G.
Abstract:: Snow water equivalent (SWE) is a critical measurement in hydrology and water resources management. Microwave remote sensing can estimate snow water equivalent (SWE). However, the algorithms used to estimate SWE require snow grain size information. Thus, determining snow grain size is pertinent to estimate SWE. Currently, there are several models...
