HEC-2 and HEC-RAS data library

Content

Here you can look at the HEC-2 and HEC-RAS files and download them for further study.

These files contain data for the HEC-2 and HEC-RAS hydraulic models developed by the US Army Corps of Engineers Hydrologic Engineering Center. The data were used to calculate water surface elevations in the creeks for previous flood insurance studies in Santa Clara County.

Please click the HEC-2 and HEC-RAS data library then select the appropriate creek from the list . If you are not sure about the name of a creek, select the general area of interest by clicking on the watershed map provided.

Note that these data files may be 20-25 years old and may not reflect the current creek condition. The District also maintains HEC-RAS and HEC-2 files that are generated in District's flood control projects. If you need those data, please contact Liang Xu at [email protected].
