WASH_2D
WASH_2D solves governing equations (parabolic partial differential equations) for two-dimensional movement of water and solute in soils with the finite difference method.
There are two variants:
- FreePascal(Lazarus) version: more featured version written in FreePascal with an integrated development environment named Lazarus including new modules (submodels) such as:
- C/C++(Qt) version: less featured, but written in more popular language, C/C++(Qt), source codes would be more easily readable and modifiable than the former.
