TUFLOW SWMM FAQ: Difference between revisions

ArcGIS Pro supports GeoPackages so this data can be viewed and edited in ArcGIS Pro. The simplest option would be to do conversions in QGIS and then work in ArcGIS Pro but would require closing the files in QGIS before working with them in ArcGIS Pro. If you have python experience, it should be possible to run the conversion tools using the ArcGIS Pro python environment but this has not been tested.

TUFLOW-SWMM is a natural choice for migrating existing XPSWMM models. It uses the same 2D engine with SGS and Quadtree and a newer version of the same 1D engine, so generally results should be nearly identical when converted. There may need to be some setup changes that might lead to minor differences in results. There are tools to convert existing models that do most of the work during a conversion, so it is quite easy. Uncommonly used features may require manual editing. Reach out to [mailto:support@tuflow.com support@tuflow.com] for assistance.

Depending on how the model was archived, this is possible. There are two parts to converting an XPSWMM model. The hydrology and 1D portions and the 2D model data. The hydrology and 1D model components can be written using the XPSWMM Viewer (2024+) without a license. The 2D model data is written by XPSWMM when running the model and is required for a full conversion. If these were not kept when the model was run, the model will need to be rerun from a licensed version of XPSWMM before conversion. Because XPSWMM writes these files using absolute paths, the file paths in the file will need to be modified if converting on a different machine or file path than was used when running the model.
