Santa Clara River Flood Assessment
Hydronia assisted Kasraie Consulting with a two-dimensional model analysis for the Santa Clara River in Ventura County, CA. The reach studied extended from the Freeman Diversion Structure to Hwy 118 Bridge downstream. The purpose of the model was to verify and/or validate FEMA's recent floodplain mapping using the latest topographic elevation data and DTM, and updated hydrology based on the HSPF model. Using a highly detailed mesh with the RiverFlow2D GPU, the model was able to capture the terrain and buildings on the floodplain.
