Introduction

QGIS is used to import the check files and review the quadtree nesting.

Method

This tutorial introduces:

Review the check files:

  1. Open the file, either:
    • Within the QGIS Browser Panel, navigate to Module_07\TUFLOW\check\M07_5m_001_Check.gpkg and double click the following layer, or
    • M07_5m_001_grd_check_R
    • In File Explorer, navigate to the Module_07\TUFLOW\check folder, drag and drop the M07_5m_001_Check.gpkg into the QGIS workspace and select the layer above.
  2. Use the 'Apply TUFLOW Styles to Open Layers'.
  3. The grd_check is the 2D grid defined by the 2d_code and 2d_qnl layers, it contains a region object for each cell. It is useful to understand how the model is orientated, the cell size in relation to the hydraulic features and where certain calculations occur in the model. In this tutorial, the level 1 grid cell size is 10m, the level 2 grid cell size is 5m.
