American Recovery and Reinvestment Act 2009 Section 110 Compliance Report for the U.S. Army Corps of Engineers, Omaha District, NHPA, Cultural Resources Investigations, Technical Report No. 26, Geographic Information Systems and Bank-Recession Modeling along the Missouri River Reservoir System

Between July 20 and September 3, 2010, Statistical Research, Inc. (SRI), conducted geomorphic investigations of a sample of reservoir banks located on U.S. Army Corps of Engineers (USACE) fee-title land around three reservoirs administered by the USACE, Omaha District (NWO): Lake Sakakawea in North Dakota, Lake Oahe in North and South Dakota, and Lake Francis Case in South Dakota. SRI investigated a total of 105 field stations in order to develop field data in support of operationalizing in a geographic information system (GIS) an existing geomorphic model for predicting bank recession. As requested, the model variables and equations were operationalized in a GIS and evaluated for each of the three lakes by SRI and their subcontractor Miratek Corporation.2010年7月20日至9月3日，统计研究公司（Statistical Research, Inc., SRI）针对由美国陆军工程兵团（U.S. Army Corps of Engineers, USACE）奥马哈分局（Omaha District，NWO）管理的三座水库周边的USACE完全产权土地上的水库岸线样本开展地貌学调查，涉及的三座水库分别为北达科他州的萨卡加维亚湖（Lake Sakakawea）、横跨北达科他州与南达科他州的奥希湖（Lake Oahe），以及南达科他州的弗朗西斯·卡斯湖（Lake Francis Case）。 SRI共计调研了105处野外站点，旨在采集野外数据以支撑在地理信息系统（Geographic Information System, GIS）中部署现有用于预测岸坡后退的地貌模型。应相关要求，SRI及其分包商米拉泰克公司（Miratek Corporation）已将模型变量与方程集成至GIS平台，并针对上述三座湖泊逐一完成了模型评估。
