| 摘要： | This report presents the findings of a study that examined three transportation projects in Alaska for potential vulnerability to climate change and extreme weather events. The study was initiated jointly by the Alaska Department of Transportation and Public Facilities (AKDOT&PF) and the United States Federal Land Management Agencies (FLMAs) through a grant provided by the Federal Highway Administration (FHWA). The focus of the study was to better understand changing climate conditions in Alaska and how this understanding could potentially lead to more informed decisions on transportation asset investments, both capital investment and operation/maintenance decisions. The three case studies included an examination of roadway exposure to permafrost thaw, airport runway exposure to sea level rise and changing wind and sea ice patterns, and slope instability related to permafrost thaw and more intense precipitation. An eleven-step process developed by FHWA for engineering vulnerability assessment was used to develop the findings for each case study. |
