• CMake2.8+
• Windows:
  • Microsoft Visual Studio 2010+ and Intel Fortran compiler (ifort) 12.0+
  • or CLion and mingw64 (with gfortran 4.8+)
• Linux/macOS:
  • GCC (with gfortran installed) 4.8+
  • ifort 12.0+

• common commands

  cd <path to SWAT>
  mkdir build
  cmake ..
  make && make install

Take VS2013 and Intel_Parallel_Studio_XE_2017 (Intel 17.0.4) as an example.

• Open "Intel compiler 17.0 Update 4 Intel(R) 64 Visual Studio 2013" from start menu.
• cd to the compile destination folder. e.g., cd D:/compile/SWAT_ifort
• Run cmake <path to SWAT src path>. e.g., cmake C:\z_code\Hydro\SWAT
  • Compile 64-bit version: cmake -G "Visual Studio 12 2013 Win64" C:\z_code\Hydro\SWAT
• Open the project SWAT2012rev664.sln, and do what you want!

If you prefer the command line, the common commands above should be OK. Note that if you want specify a Fortran compiler, please add the following command before cmake command.

export FC=/path/to/your/own/Fortran/compiler
# e.g., ifort
export FC=/share/soft/intel/composer_xe_2011_sp1.6.233/bin/intel64/ifort
# e.g., gfortran
export FC=/home/zhulj/gcc4.8.4/bin/gfortran

However, if you want a user-friendly IDE for to learn and improve the SWAT model, I recommend the cross-platform IDE CLion with Fortran plugin.

CLion use CMake to manage projects. Under Windows, you may also install mingw64 (or mingw) for the gfortran compiler.

Using CLion is quite easy and intuitive. Just open the SWAT path from File -> Open.... Then CLion will automatically load the project by CMakeLists.txt existed in SWAT directory. Now, you can build SWAT model by typing Ctrl+F9 or clicking the build button.

In order to make it easier to track code changes and keep up with newer revisions, I use subtree to manage the SWAT source code from tamu.

• Set subtree as swat_src(only do once at the very beginning of this repository)

   git remote add -f swat_src [email protected]:crazyzlj/swat_src_tamu.git
   git subtree add --prefix=swat_src swat_src master --squash

• Do any modification to the swat_src to meet our specific needs.

• If the SWAT source is updated we should pull the latest code from swat_src_tamu and merge it.

  git fetch swat_src master
  git subtree pull --prefix=swat_src swat_src master --squash

• 9/11/2017: Bugs fixed or code improvement. Cross-platform compilation.

  • Code improvement:

    !! 1. Error: Symbol 'XXX' at (1) has no IMPLICIT type
    !! 2. Function 'XXXX' at (1) has no IMPLICIT type

  • Bugs:

    !! 1. Typo
    !! e.g., hhwatqual.f
    if (orgpin < 1.e-6) orgnpin = 0.0
    !! should be
    if (orgpin < 1.e-6) orgpin = 0.0
    !! 2. Float equal
    if (rg_orifice(i,kk)==1) then
    !! changed to
    if (abs(rg_orifice(i,kk)-1.)<1.e-5) then
