Numerical Simulation of 1D Advection-Dispersion Equation of Conservative Tracer with Oscillating Tidal Flows

Model archive for a numerical simulation of the one-dimensional advection-dispersion equation of a conservative tracer with oscillating tidal flows. The numerical simulation was used to examine how a conservative tracer evolves along a tidal channel. Scenarios were run to examine the effects increased dispersion, increased and decreased mixing at a channel junction, and increased advection. Code for the model was developed in Matlab (MathWorks® Inc., 2019). Model code, input and output files, and plotting scripts are available with this release. Details of the parameters used in the simulation and results are described in Stumpner et. al 2020. The README.doc file contains description of files provided and instructions to run the model.
