QGIS SWMM GeoPackage Add Sections

From Tuflow
Jump to navigation Jump to search


This tool adds tables representing SWMM sections to an existing GeoPackage. The formatting is compatible with the TUFLOW-SWMM tools for writing SWMM inp files. It is recommended to use this tool in conjunction with the GeoPackage - Create processing tool to eliminate potential future errors.

Note: This tool updates the existing GeoPackage file. If a selected SWMM section already exists in the GeoPackage, the tool replaces it, resulting in the loss of any saved data in that section.


This tool, GeoPackage - Add sections, can be found in the QGIS processing toolbox panel under TUFLOW >> SWMM. To open the Processing Toolbox panel, navigate to 'Processing' in the menubar and select 'Toolbox'.
