One-dimensional longitudinal dispersion model

Hello everyone

I would like to simulate water quality in a river.

and I want to program and solve this equation (attached file) only in 1D.(where C is the concentration that im looking for, Dx, Vx,K,Sinterne are constantes that I can calculate them using simple equations)

Im a geologiste so I have a limited knowledge of maths.

As I read before, this equation can be solve in Matlab using PDE solver (https://fr.mathworks.com/help/matlab/ref/pdepe.html).

Can you please give me some advices about how I can make this simulation?

Best regards

Ismail

You forgot to attach the file. You will need initial and boundary conditions to solve the equation.
