Tutorial to simulate a contaminant plume from a waste dump with MODFLOW MT3DMS
/
Quick tutorial for the simulation of a contaminant plume from a waste dump.
This tutorial cover the following parts:
Review of the groundwater flow regime
Water table plot on cross section
Set up of MT3DMS packages (ADV, DSP, SSM) and the contaminant species
Setup of MODFLOW time
Run the groundwater flow model
Definition of hydraulic parameters and background concentration
Implementation of the Waste Dump as a source on the Water Table
Run the mass transport simulation
Import results
The simulated species on this tutorial and their background concentration / source concentrations in mg/l are listed below
Sulphate: 0.448 / 1290
Fe: 2.61 / 286
Some other parameters related to the contaminant transport are:
Longitudinal Dispersivity: 10
Porosity: 0.02

FloPy is the Python library that builds and executes MODFLOW models; this library has been enhanced to provide full support of MODFLOW 6 with most of its recent development is related to functionality for MODFLOW 6, tools to use vector and raster spatial data and common plotting and export functionality.
