TUFLOW CATCH Tutorial Introduction
Introduction
The following tutorial models are aimed at new and experienced users, stepping through the process of building and running TUFLOW CATCH together. These tutorials aim to demonstrate the power and flexibility of TUFLOW CATCH in simulating catchment-wide hydrologic, hydraulic, pollutant export, and receiving waterway processes. TUFLOW CATCH enables detailed simulation of surface and subsurface flows, pollutant transport, and downstream environmental impact without relying on lumped or average assumptions.
Note, if you are not already familiar with TUFLOW, we recommend first completing Module 1, 2, 3 and 6 of the TUFLOW Tutorials to establish an understanding of 1D and 2D modeling, as well as direct rainfall models.
Software Requirements
TUFLOW uses QGIS as its Graphical User Interface (GUI), in combination with text editor and spreadsheet software, for its model creation and result viewing. The group of software creates an extremely workflow efficient and flexible modeling environment. Notably, QGIS does not experience the data load/visualization lag and display issues some other hydraulic modeling software GUI's are limited by when working with larger datasets.
| Requirement | Brief Description | Download |
|---|---|---|
| TUFLOW | TUFLOW is a computer program for simulating depth-averaged, one and two-dimensional free-surface flows such as occurs from floods and tides, with the 2D solution occurring over a regular grid or quadtree mesh of square elements. It is recommended to always use the latest release version of TUFLOW. This tutorial model does not require a TUFLOW license. This tutorial is configured to use a NVIDIA GPU card. If this is not available, your CPU can be used via the Hardware command. |
The TUFLOW executable is provided within the Tutorial Download Dataset. |
| QGIS QGIS TUFLOW plugin QGIS TUFLOW CATCH plugin |
QGIS is the Geographic Information System (GIS) Graphical User Interface (GUI) used to build models and view results. The QGIS TUFLOW plugin includes numerous tools to increase workflow efficiency. The QGIS TUFLOW CATCH plugin includes CATCH specific tools.
This tutorial was developed using QGIS 3.42, QGIS TUFLOW plugin 3.14 and QGIS TUFLOW CATCH plugin 0.48. Please use these or newer versions of QGIS and the plugins. |
Latest 64-bit version of QGIS. QGIS TUFLOW Plugin Installation. QGIS TUFLOW CATCH Plugin. For instructions on installing a plugin from a ZIP, see Install from ZIP. |
| NotePad++ Syntax Highlighting |
A text editor is required for creation of the TUFLOW control (script) files. This tutorial was developed with NotePad++. Ideally a text editor should be able to:
TUFLOW color coding can be enabled using syntax highlighting. |
Latest 64-bit version of Notepad++. TUFLOW syntax highlighting for Notepad++. For instructions on configuring Notepad++ for TUFLOW modeling, see Notepad++ tips. |
| Microsoft Excel | A spreadsheet software is required for working with tabular data and .csv files. This tutorial has been created using Excel. |
Tutorial Data
To build the tutorial model, download the dataset below. This includes a digital elevation model (DEM), aerial photography, background model data for the tutorial model and a working version of the model. GeoPackage database has been used as the GIS format for the model build tasks. For tips on using GeoPackage databases see GeoPackage Tips.
Tutorial Modules
The download dataset contains the input files and working version of the tutorial model for reference. Results and check files are not included to keep the size of the download file manageable; they will be created when running the model simulations. The folder should be placed in a location with write permissions.
The tutorial model is presented in several modules. All modules can be completed independently, however new users are encouraged to undertake the modules in sequence:
- TUFLOW SWMM Module 1 - 1D SWMM Culverts
- TUFLOW SWMM Module 2 - 1D SWMM Pipe Network / 2D TUFLOW Direct Rainfall Hydrology
- TUFLOW SWMM Module 3 - 1D SWMM Pipe Network / 1D SWMM Urban Hydrology
- TUFLOW SWMM Module 4 - 1D SWMM Pipe Network / 1D SWMM Urban Hydrology: Executing multiple different event simulations from a single model control file.
