SIR2016-5029_cfwgoshor_2: Flood Inundation Depth for a Flow of 15,000 cfs at the Gage Coast Fork Willamette River at Goshen, Oregon

The domain of the model is as follows: Row River from Dorena dam to the confluence with the Coast Fork; Coast Fork from Cottage Grove dam to the confluence with the Middle Fork; Silk Creek from River Mile 1.7 to the confluence with the Coast Fork. The basis for these features is the Willamette Flood Insurance Study – Phase One (2013). The hydraulics and hydrology for the FIS were reused in the production of these polygons; the reports and information associated with the FIS are applicable to this product. The Digital Elevation Model (DEM) utilized for the Willamette FIS submittal was produced by combining multiple overlapping topographic surveys for the Middle Fork and Coast Fork of the Willamette River. This DEM was created from four [...]

该模型覆盖的流域范围如下：多里纳大坝（Dorena dam）至与海岸叉河汇流处的罗河（Row River）；科蒂奇格罗夫大坝（Cottage Grove dam）至与中叉河汇流处的海岸叉河；河英里1.7处至与海岸叉河汇流处的希尔溪（Silk Creek）。上述流域特征的划定依据为《威拉米特洪水保险研究——第一阶段（2013）》（Willamette Flood Insurance Study – Phase One (2013)）。本次生成此类地理多边形要素时复用了该洪水保险研究（Flood Insurance Study, FIS）中的水力学与水文学数据，该FIS配套的相关报告与信息同样适用于本数据集产品。用于威拉米特河FIS提交工作的数字高程模型（Digital Elevation Model, DEM），通过整合威拉米特河中游支流与海岸叉河的多份重叠地形测量数据制作完成。该DEM由四份[...]
