East Fork White River near Seymour, IN, processed DEM

This is a lidar DEM originally downloaded from Open Topography, a bathymetric surface has been added to the river from survey data collected in October 2016, and roadways have been cut out at select locations so that water can be conveyed across the floodplain surface at culverts that could not otherwise be added to a 2D HEC-RAS model.

本数据集为从Open Topography原始下载的激光雷达数字高程模型（DEM），其中加入了2016年10月收集的测量数据所形成的河床地形，并在特定位置裁剪了道路，以便水流能够通过无法添加至二维HEC-RAS模型的涵洞穿越洪水平原表面。
