Geospatial data sets and hydraulic models for selected streams in Stark County, Ohio

Digital flood-inundation maps for selected streams in Stark County were created by the U.S. Geological Survey (USGS) in cooperation with the Muskingum Watershed Conservancy District and the Stark County Commissioners as part of a Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The flood-inundation maps show estimates of the areal extent corresponding to the 1% and 0.2% annual-exceedance probability floods. Flood profiles were computed for the stream reach by means of the one-dimensional step-backwater model.

美国地质调查局（U.S. Geological Survey, USGS）联合马斯金格姆流域保护区与斯塔克县委员会，作为联邦紧急事务管理局（Federal Emergency Management Agency, FEMA）洪水保险研究（Flood Insurance Study, FIS）项目的组成部分，制作了斯塔克县内选定溪流的数字洪水淹没地图。该洪水淹没地图展示了年超越概率分别为1%与0.2%的洪水对应的淹没范围估算值。研究人员借助一维回水模型，对所涉河段的洪水剖面进行了计算。
