Reactive Transport Modelling in 1d, 2d and 3d R package ReacTran version 1.4.3.2 CRAN Task View: DifferentialEquations (https://CRAN.R-project.org/view=DifferentialEquations) Routines for developing models that describe reaction and advective-diffusive transport in one, two or three dimensions. Includes transport routines in porous media, in estuaries, and in bodies with variable shape.
