Hi there, I have read your project of "Numerical Study of Longitudinal dispersion in open channels" with deep interest.
It seems you want to compare the empirical , numerical and exact values of the concentration. I have done similar works
[login to view URL] my portfolio for details. I suspect you want to solve a 1D advection -dispersion equation(ADE) which is used
to predict the concentration/pollutants. I will deliver quality work in record time. Chat with me for further details of budget and deadlines and of course the model equation and initial conditions(IC) and boundary conditions(BCs). I will useExplicit Finite difference formulations with keen consideration of stability criterion. Thanks. Albert.
