Output Files
FM2PROF generates a set of output files that can be used to set up 1D hydraulic models. This page describes the output files that are generated and their purpose.
Output Directory Structure
After running FM2PROF, the output files are organized in subdirectories:
output/
├── fm2prof.log
├── dflow1d/ # D-Flow 1D format files
│ ├── CrossSectionLocations.ini
│ ├── CrossSectionDefinitions.ini
│ ├── roughness-Main.ini
│ ├── roughness-FloodPlain1.ini
│ ├── roughness-FloodPlain2.ini
│ └── volumes.csv
└── dhydro/ # D-Hydro (1D) format files
│ ├── crsloc.ini
│ ├── crsdef.ini
│ ├── roughness-Main.ini
│ ├── roughness-FloodPlain1.ini
│ ├── roughness-FloodPlain2.ini
│ └── volumes.csv
└── debug/ # Optional debug files (if enabled in configuration)
├── cross_section_volumes.geojson
├── face_output.geojson
└── edge_output.geojson
Note
The "dflow1d" format is only used by the SOBEK 3 software from version 3.5 and higher. Support for SOBEK 3.4 and lower has been dropped since FM2PROF version 2.5
File Differences between dhydro and dflow1d (SOBEK 3)
The dhydro and dflow1d formats are alternative output formats with slightly different file naming conventions. The dflow1d is used by SOBEK 3, while dhydro is used by the D-Hydro 1D2D software.
dflow1d |
dhydro |
Description |
|---|---|---|
| CrossSectionLocations.ini | crsloc.ini | Cross-section locations |
| CrossSectionDefinitions.ini | crsdef.ini | Cross-section definitions |
| roughness-*.ini | roughness-*.ini | Roughness files (same naming) |
| volumes.csv | volumes.csv | Volume comparison (same naming) |
Output Format
The D-Flow 1D format is the default output format and generates files compatible with Deltares D-Flow 1D software.
CrossSectionLocations.ini / crsloc.ini
This file contains the spatial locations of the cross-sections along the river or channel network.
Example:
CrossSectionDefinitions.ini / crsdef.ini
This file contains the geometrical definitions of each cross-section, including the shape and dimensions.

roughness-x.ini
This file contains roughness coefficients for a section of the cross-section. Valid sections are "main", "floodplain1" and "floodplain2". FM2PROF always output the values as Chézy coefficient.
