ABSTRACT The Longwood Institute of Archaeology conducted the Vulnerability, Potential and Condition (VPC) assessment of shoreline archaeological sites along 1990 km (1237 miles) of the Chesapeake Bay in Virginia. VPC assessment involves a three-pronged approach that includes (1) the assessment of site vulnerability due to changing shorelines using an analytical package called Analysing Moving Boundaries Using R – AMBUR, (2) the assessment of potential shoreline site locations through predictive modelling using Weights of Evidence – WofE – analysis, and (3) the assessment of current conditions of known sites through direct observation. Vulnerability assessment results indicated that 49% of site shorelines in the project area are moving landward. Potential assessment located high-probability site locations with an 83% efficiency. Condition assessment, conducted using standard field protocols, provided feedback of the sites’ current conditions. The intended outcome of this method is to provide resource managers with information needed to make informed, data-driven management decisions.

图书馆着火了，现在怎么办？评估损害及其处理方法：切萨皮克湾的案例研究

摘要Longwood考古研究所对弗吉尼亚州切萨皮克湾1990公里（1237英里）沿岸的考古遗址进行了脆弱性，潜力和条件（VPC）评估。VPC评估涉及三个方面的方法，其中包括（1）使用名为R – AMBUR的分析移动边界的分析包来评估由于海岸线变化引起的站点脆弱性，（2）通过使用权重的预测建模来评估潜在的海岸线站点位置证据– WofE –分析，以及（3）通过直接观察评估已知地点的当前状况。脆弱性评估结果表明，项目区域49％的工地海岸线正在向陆地移动。潜力评估以83％的效率定位在高概率站点位置。使用标准现场协议进行的状况评估可提供站点当前状况的反馈。该方法的预期结果是为资源经理提供做出明智的，数据驱动的管理决策所需的信息。
