The simulation of solute transport in groundwater flow systems has evolved rapidly in recent years, driven by the increased interest in knowledge of aquifer pollution. The design of remediation systems for groundwater contamination requires a broad understanding of how various processes –advection, dispersion and chemical reactions– interact with the movement and fate of contaminants. The MT3DMS package, implemented by MODFLOW, provides a tool for synthesizing these processes, evaluating their interactions and testing the effectiveness of groundwater remediation measures.

Hatarilabs offers the virtual course of Contaminant Transport Modelling using MODFLOW and MT3DMS for students and professionals from any country. Now you can be trained in contaminant transport modelling using MODFLOW and Model Muse anywhere without any pre-set schedule. To access the available material and receive support, you just have to make a payment. The course includes certification.

Objectives

The six-session course provides the participant with essential knowledge of the basic principles governing the transport of contaminants. At the end of the course the participant will be able to:

Understand the processes of advection and dispersion transport, such as the chemistry that influences them.
Develop MODFLOW models that represent the contaminant transport conditions in groundwater regimes.
Perform visual post-processing to the transient flow of the contaminant plume.
