Setting Up Heterogeneities and Remediation Schemas for Contaminant Plumes with MODFLOW + MT3D

Aquifers can be porous, fractured or karstic. Due to the geological setup and processes related to the formation of the porous media, these acuifers can present a high degree of heterogeneity that affect/impact the groundwater flow patterns and contaminant transport and distribution.

Contaminant plumes for puntual/aerial sources interact with aquifer heterogeneities and anisotropies. Understanding and conceptualizing the distribution of the different hydrogeological units and their properties on the subsurface is a challenge for hydrogeologist, numerical modelers and remediation specalists.

This tutorial shows a procedure to insert low hydraulic conductivity (low K) areas on the aquifer model and analyze the development of the contaminant plume around this area. Options for aquifer remediation as interception wells are also implemented on the model and its performance is evaluated based on the contaminant transport model results.

Geometry construction and implementation of boundary conditions were developed on another tutorial. For more information please follow this link:
