We obtained bathymetry data of this section of the Yahara River from John Reimer. In addition to the local bathymetry data, we also used LIDAR elevation data of the surrounding area. We combined the data using Global Mapper into a single elevation file.
After importing the local elevation data into RAS MAPPER, we manually defined the river center-line, the right and left river banks, and the floodplain.
There are 11 bridges along this section of the Yahara River. We created these bridges in the geometry file with some general assumptions about the bridges. We assumed the road deck to be six feet tall, and the bottom of the bridge to be three feet above the riverbank. A more detailed bridge analysis could be conducted in the future to expand upon this model.
