Introduction
QGIS is used to import the check files and review the dam break.
Method
This tutorial introduces:
Review the check files:
- Open the following files from the Module_10\TUFLOW\check folder:
- M10_5m_001_DEM_Z.tif
- M10_5m_001_zsh_zpt_check_P.shp
- M10_5m_001_vzsh_zpt_check_P.shp
- M10_5m_001_sh_obj_check_R.shp
- M10_5m_001_grd_check_R.shp
- M10_5m_001_bcc_check_R.shp
- M10_5m_001_sac_check_R.shp
- Use the 'Apply TUFLOW Styles to Open Layers'.
- The DEM_Z grid shows the final elevations (at time 0) used for the model calculations. The elevation changes due to the dambreak are inspected in the Results section.
- The zsh_zpt_check file contains the Zpts modified by the 2d_zsh layers with updated elevation, change in elevation and source layer. The Shape_Width attribute is specified the same as the cell size, a thick breakline is used with entire cells being modified. The TUFLOW style colour codes the symbols based on the amount raised, or lowered.
- The vzsh_zpt_check file contains information on the elevation points that change over time, elevation change, final elevation and trigger conditions.
- The sh_obj_check file displays the TIN triangles created by TUFLOW during the model initialisation and is useful to review for all merge polygons.
- The grd_check is the 2D grid defined by the 2d_code layer and contains a region object for each cell with attributes, e.g. the IWL.
- The sac_check contains information on the lowest cells for each SA boundary region. The upstream 2d_bc QT inflow was replaced with a 2d_sa inflow.
- The bcc_check contains information on the 2D boundaries, it shows the cells conveying water out of the model selected by the 2d_bc HQ type boundary (based on a slope).
Conclusion
- The topographic modifications representing the dam wall, dam break and initial water level were inspected.
