PlumeCalc

The PLUMECALC application determines resident or flux-averaged concentrations in groundwater flow models using the results from a random-walk particle tracking model simulation. The model assumes that the particle tracking simulation accurately characterizes the transport solution to the Advection-Dispersion equation (ADE) for one or more source locations. These particle tracking results, combined with solute input information such as mass flux input functions, sorption, diffusion, and decay parameters, are used to resolve the concentration within the model system or at fluid exit points. The code was initially developed to be compatible with the FEHM fluid flow and random- walk particle tracking model (Dash, 2003). Therefore, the code requires auxiliary input information related to the flow and transport model, such as the grid geometric information. The code implements the Convolution-Based Particle Tracking (CBPT) method.

• Version 2.3.3 (May 2011)

"Version_notes.txt"

This latest version of PLUMECALC corrects a subgridding issue that lead to an over calculation of concentration no matter what level of subgridding was used. This problem has been corrected by doing the time delay calculations after the subgridding. The problem was found and corrected by using subgridding in PLUMECALC on a simple model that used FEHM streamline particle tracking with dispersion.

The manual V2.3.2 was not updated because the updates did not change how the code is run or basic functionality.

• Version 2.3.2 (April 2011)
