Creator:: Coulter, Elizabeth Dodson
Abstract:: The prioritization of road maintenance projects is an important forest engineering task subject to limited budgets and competing investment needs. Large investments are made each year to maintain and upgrade forest road networks to meet economic and environmental goals. Many models and guidelines are available for single-criterion analysis of forest...
Resource Type:: Dissertation

Creator:: Thompson, Matthew P.
Abstract:: One of the basic questions facing transportation planners and road managers is how to provide and maintain a road system that provides efficient access to the forest while limiting adverse effects roads can have on water and soil resources. The purpose of this study is to develop decision support models...

Full Text:: regular maintenance, upgrading, and road removal. The first chapter describes the challenges

Creator:: Levesque, Stephen P.
Abstract:: Because of their potential for adversely affecting aquatic resources, increased rates of erosion and sedimentation associated with low-volume forest roads have recently gained the attention of land managers in the Pacific Northwest. For example, on the Tongass National Forest in Southeast Alaska, there is an urgent need to explore the...

Creator:: Feeney, Daniel John
Abstract:: This thesis describes the results of a project conducted to determine the economics of forest road maintenance alternatives between periods of timber harvesting. An open road and a closed road alternative will be compared to the economics of clearcutting an entire area and obliterating the road system until reentry at...
Resource Type:: Masters Thesis

Creator:: Akay, Abdullah Emin
Abstract:: The systems currently available for forest road design are not capable of making computer-aided design judgments such as: 1) automated generation of alternative grade lines, 2) optimizing vertical alignment, 3) minimizing total cost of construction, maintenance, and transportation costs, and 4) aiming for least environmental impacts. In recent years, advances...
