# Reactive transport modelling in 1D, 2D and 3D

### Description

R-package ReacTran contains routines that enable the development of reactive transport models in aquatic systems (rivers, lakes, oceans), porous media (floc aggregates, sediments,...) and even idealized organisms (spherical cells, cylindrical worms,...).

The geometry of the model domain is either one-dimensional, two-dimensional or three-dimensional.

The package contains:

Functions to setup a finite-difference grid (1D or 2D)

Functions to attach parameters and properties to this grid (1D or 2D)

Functions to calculate the advective-diffusive transport term over the grid (1D, 2D, 3D)

Utility functions
