What is a G03 file

G03 files mostly belong to HEC-RAS by U.S. Army Corps of Engineers. Hydrologic Engineering Centers River Analysis System (HEC- RAS) is a one-dimensional steady flow hydraulic model designed to aid hydraulic engineers in channel flow analysis and floodplain determination. The results of the model can be applied in floodplain management and flood insurance studies. These files can have extensions from G01 through G99.

How can I open a G03 file?

You need a suitable software like HEC-RAS to open a G03 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your G03 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a G03 file directly in the browser:. Just drag the file onto this browser window and drop it.
