GRATE has been in development since 2006 - it has had many incarnations for different applications in gravel bed sediment routing problems. The code provided here is built on the Qt Open Source framework; you will need Qt Creator and associated libraries to compile the GUI version of the code. There is also a commond line (headless) version that builds with no dependencies on Qt. In both cases the CMake build system is used. While I have worked on development of this particular strand of the code, I acknowledge my collaborators Jeremy Walsh and Murray Hicks from NIWA Christchurch, who have been key developers and mentors in getting this project off the ground.

The code is inspired by Gary Parker's classic 1D sediment transport formulations (e.g. ACRONYM; see Gary's Morphodynamics Web Page: http://hydrolab.illinois.edu/people/parkerg/), though it employs many routines that have been developed in the intervening 25 years or so, including cross-section and floodplain specification, tributary additions, non-erodible sections, gravel abrasion, multiple lithologies, and optimisation of channel width. The abrasion and lithology routines are based on Cui et al. (e.g. TUGS, DREAM). The width optimisation model is based on algorithms developed by Brett Eaton (https://blogs.ubc.ca/beaton/working-code/). For calculating the water energy profile, one has the choice of employing a standard explicit backwater formulation based on Parker's model, or an implicit formulation that is based on Chaudhry (2008).

Application of the code can be found in Tunnicliffe and Church, 2015 (doi:10.1002/2014JF003370) and Tunnicliffe, Eaton, Fuller, Marden and Peacock (2018; forthcoming).

The code has been developed using the Qt open source IDE (https://www1.qt.io/download/). While the key algorithms are written in fairly generic C++, the 'main' header, 'mainwindow.cpp' and 'RwaveWin.ui' elements link operation to a GUI-based framework, allowing for easy model execution and observation of the evolving river profile. The latest version of the code (Nov 2017) has been compiled with Qt 5.9 (QtCreator 4.4). If you have the Qt framework installed, you can open 'CMakeLists.txt' as a project, and compile and run from QtCreator. Otherwise, see below for more information about building the code.

The code consists essentially of five modules - MainWindow, Model, RiverProfile, Hydro and Sed. MainWindow sets up the Qt graphical interface and handles user input, including start of the simulation. Model runs the simulation. RiverProfile builds the data object that contains all of the cross-section and river profile information. It reads in the model setup information from a .dat file. The Hydro and Sed modules handle all of the routines that relate to hydraulics and sediment transport, respectively.

As development work proceeds, more documentation will be provided here.

Building the code

CMake and a C++ compiler are required. Qt is optional (only required if you want to build the GUI)

QtCreator (Windows, Linux, Mac)

Load CMakeLists.txt as a project in QtCreator.

Command line (Linux, Mac)

Install the dependencies. For example on a Mac one could install homebrew and then install CMake and qt with brew install cmake qt.

Build with CMake:

mkdir build && cd build  # create a directory for the build and change to it
cmake ..                 # configure the build (both the GUI and CLI builds will be compiled by default)
make                     # build the code
ctest                    # test the code

This will build two executables; GrateRip is the GUI version, GrateRipCLI is the command line version. The same input file works with both.

The CLI/headless version has no dependency on Qt or any other libraries. To disable the GUI version (and build without any dependency on Qt) specify the configuration options:

...
cmake .. -DBUILD_GUI=OFF
...

This will build only the GrateRipCLI command line version.

If you just want to build the GUI version and not the CLI version, the configuration line is:

cmake .. -DBUILD_CLI=OFF

Different compilers can be specified at the configure step by setting the CXX environment variable. For example, if you have the Intel C++ compiler (icpc) installed and wish to use it:

...
CXX=icpc cmake .. [OTHER_OPTIONS]
...

See the .travis.yml file for an example of building on Linux.

CMake (Windows)

It should be possible to build the CMake version on Windows too. This has been tested with QtCreator and MSVC both using CMake.

To build with MSVC one should first install and run CMake.

  1. Select the source directory and an empty build directory
  2. Select the 64 bit build
  3. Run configure
  4. If it fails due to not finding Qt, add a new variable called CMAKE_PREFIX_PATH equal to the Qt install (e.g. C:\Qt\5.12\msvc2017_64) and the rerun configure
  5. Next generate, this should generate the MSVC project files that can be loaded into MSVC

Load the project file in MSVC.

You may need to add the Qt binary directories to PATH so they can be found at runtime. For example, append the following directories:

  • C:\Qt\5.12\msvc2017_64\bin
  • C:\Qt\5.12\msvc2017_64\plugins\platforms
