What is a BASIN file?

BASIN files mostly belong to Hydrologic Modeling System (HEC-HMS) by U.S. Army Corps of Engineers. The Hydrologic Modeling System (HEC-HMS) is designed to simulate the precipitation-runoff processes of dendritic watershed systems.

How to open BASIN files

You need a suitable software like Hydrologic Modeling System (HEC-HMS) to open a BASIN file.

Can't Open Your .BASIN File? Try These Steps

Because .BASIN files can originate from different specialized programs, they aren't universally openable by standard applications.

Identify the Source: If received from a hydrologist or civil engineer, it is likely a Basin Model Settings file used in watershed simulations.
Check the Header: Open the file in a text editor to inspect the first few lines.
- Plain text with parameters suggests a standard HEC-HMS model file.
- "PK" or garbled characters indicate a compressed or proprietary binary format.
Use the Original Software: You usually need the original program to open it properly; try the U.S. Army Corps of Engineers' Hydrologic Modeling System (HEC-HMS), or ask the sender for the required software.
Use this Webpage: Drag and drop your .BASIN file into our viewer to detect its exact format, extract readable text, and preview its contents.
