QGIS SWMM Junctions Convert HX Nodes to Storage

From Tuflow
Jump to navigation Jump to search

Introduction

This tool converts junctions attached to HX connections (embankment culverts) to storage nodes. This is necessary to accurately represent storage in the system as HX cells do not track storage. The use of storage nodes also improves model stability. Note: Pyramidal storage shapes with 0.0 inverse slope (vertical) that are approximately the typical area of connected HX nodes should be used by default. If there are large differences in areas within the model, these values can be modified to better represent outliers.

Usage

This tool, Junctions - Convert HX nodes to storage, 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'.
