Extract text from HydroCAD unit hydrographs (HUH)
To convert HUH unit hydrographs to another format, you need HydroCAD or other Data software.
To convert other file formats to the "Hydrograph Definitions Data" file type, you need software like HydroCAD or a similar tool.
The .huh file is a HydroCAD Unit Hydrograph Definitions file. It stores mathematical models and coordinate data used by civil engineers to calculate stormwater runoff behavior.
This format is developed exclusively for HydroCAD, a specialized hydrology and hydraulics design application.
The primary disadvantage of the .huh format is its closed, proprietary nature. Files are essentially locked to the HydroCAD ecosystem, which requires an expensive commercial license. You cannot open these files natively in web browsers, and standard spreadsheet software cannot read the raw proprietary data structure without prior formatting.
To share this engineering data with clients or regulatory agencies, you must convert the file to widely supported formats like CSV (for data analysis) or PDF (for reporting).
Because this is a closed engineering format, standard online converters fail to process it. Our tools can inspect the underlying file code. If the file contains unencrypted text or embedded data, we can help you extract the raw numbers even without the original software.
Convert.Guru analyzes your HUH file, detects the exact format, and lets you read the text inside.
Users also converted HCI, HCE and HCU files.
If you want to convert HUH file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use HydroCAD or similar software from the "Stormwater Runoff Mathematical Modeling" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to HUH, try HydroCAD or another comparable tool in the "Stormwater Runoff Mathematical Modeling" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our HUH converter.
