- Import in an empty 2d_bc_empty.TAB layer from within the TUFLOW\model\mi\empty folder and save as 2d_bc_hxi_FMT_001.TAB.
- Open the 1D_2D_Points.TAB GIS layer from Module_Data\Module_01\mi folder. Select all objects from within this layer, copy and paste into 2d_bc_hxi_FMT_001.TAB.
- Interrogate one of the digitised points and inspect the attributes. The ‘type’ attribute is ‘ZP’ to denote that it is a z-point. The ‘f’ attribute is the elevation of the bank link in mAOD.
- Export to .MIF format in preparation for reading into TUFLOW. Please return to the Flood Modeller Tutorial Model module 1 page here.
Introduction
In this section we will define the bank elevations of the watercourse. These are the elevations of the 1D/2D boundary cells that link the 1D Flood Modeller watercourse to the 2D TUFLOW floodplain. Note that it is these cell elevations that determine whether out of bank flooding occurs and not the left/right bank elevations with the Flood Modeller 1D cross-sections.
Method
