OneD

Excel implementation of analytical solutions for one-dimensional transport of solutes in groundwater.

These solutions are capable of representing the following physical transport processes:
  • One-dimensional advection;
  • One-dimensional dispersion (mechanical dispersion and molecular diffusion);
  • Linear, equilibrium sorption; and
  • First-order transformation reaction.

ONED_1:
Excel - Based Analytical Solution for One-Dimensional Solute Transport with a Type 1 (Dirichlet) Boundary Condition at the Inlet.

​Key Features

  • General time-varying source concentration history can be specified, with the automatic creation and display of the source history
  • A non-zero initial concentration may be specified
  • User- Friendly Input / Output
  • Breakthrough curve and concentration-profile plot output in Excel and .PNG formats

 

ONED_3:
Analytical Solution for One-Dimensional Solute Transport with a Type III (Cauchy, Robbins, radiation, natural) Boundary Condition at the Inlet

​Key Features

  • General time-varying source mass flux history can be specified, with the automatic creation and display of the source history
  • A non-zero initial concentration may be specified.
  • User- Friendly Input / Output
  • Breakthrough curve and concentration-profile plot output in Excel and .PNG formats​
