TUFLOW CATCH Tutorial M04 Draft

Page Under Construction

Introduction

In this module, a TUFLOW CATCH integrated model with interventions is developed.

TUFLOW CATCH Tutorial Module 4 is built from the model created in TUFLOW CATCH Module 3. The completed TUFLOW CATCH Module 03 is provided in the TUFLOW_CATCH_Module_04\Modelling folder of the download dataset as the starting point for this tutorial. If you are not already familiar with TUFLOW CATCH, we recommend completing TUFLOW CATCH Module 1, TUFLOW CATCH Module 2 and TUFLOW CATCH Module 3 prior to starting this tutorial.

GIS Inputs

Create, import and view input data:

• QGIS GIS Inputs

Simulation Control Files

The following steps will require use of a text editor. The tutorial demonstration uses Notepad++. For its configuration information refer to Notepad++ Tips.

TUFLOW CATCH Control File (TCC)

Global Settings

For this tutorial, leave all commands as is. This section of the .tcc was populated in TUFLOW CATCH Tutorial 1.

Catchment Hydraulic Model

For this tutorial, leave all commands as is. This section of the .tcc was populated in TUFLOW CATCH Tutorial 3.

Pollutant Export Model

This block contains commands that control the pollutant export (and other constituent) simulation. For this tutorial, the pollutant export model block must be updated to include interventions.

1. Save a copy of TC03_001.tcc as TC04_001.tcc in the TUFLOW_CATCH_Module_04\Modelling\TUFLOWCatch\runs folder. Open TC04_001.tcc in a text editor.
2. In the 'Interventions' section, update the following command to reference the interventions (2d_im) layer created earlier in this tutorial.
   Read GIS Intervention == ..\..\TUFLOW\model\gis\2d_im_TC04_001_L.shp ! GIS layer defining interventions
   
3. In the 'Mass Removal Properties' section, add the following device block. This block defines the default (or spatially uniform) mass removal methods ?for all pollutants? for all devices. Including it is considered best practice, as it ensures that all devices have their mass export properties specified. For more information on the mass removal parameters, please refer to the section of the catch manual.
