An Advection Diffusion Equation Finite Difference Model for predicting transverse concentration profiles from variable depth, velocity, and transverse dispersion coefficient profiles.

The MATLAB function ADE_FDM provides an implementation of the double sweep algorithm to numerically solve the 2D Advection-Diffusion Equation, Equation 3, in finite difference form, Equation A1 from West et al., 2021 in the MATLAB programming language.

This deposit includes the model code, ADE_FDM.m as well as the FDMdemo.mlx live script and FDMdemo.pdf version of the live script demonstrating the use of the model code.
