Basic Concepts of Groundwater Modeling with MODFLOW and Model Muse

MODFLOW is a software for groundwater modeling developed by the USGS. The software is capable of representing conditions related to groundwater flow such as evapotranspiration, recharge, drainage, river interaction among others. Its finite different approach gives the capability to calculate the flow regime with exceptional control on water budget discrepancy. With MODFLOW one can rely on that the flow going in the model is the same as the flow going out of it, from the regional scale and on cross sections.

MODFLOW was designed to calculate water heads and groundwater flow regimes, and it can be coupled with a strong transport model as MT3DMS. A good tool for particle tracking modeling is MODPATH, this software is capable of calculating flow lines and time related to particles on groundwater flow.

The latest and most comprehensive pre-processing software is MODEL MUSE, which implements most features of MODFLOW and MT3DMS.

MODEL MUSE has a high performance due to the “design by objects” concept that optimizes the conceptualization of boundary conditions edges and other hydraulic parameters, reducing model construction time and improves output data interpretation.

Tutorial Seawater Intrusion in Coastal Aquifers with MODFLOW-SWI2

Continue exploitation of groundwater in arid climates generates extreme scenarios of groundwater flow and storage. As pumping rate increase, inflows from recharge, storage and seawater increase.  With time, seawater is introduced into the aquifer, reaching its wells and affecting water quality. This tutorial shows the impact of intense groundwater exploitation of 50 wells in a simulation period of 60 years.

Tutorial to transform a 3D into a 2D Dam Seepage Model with MODFLOW

Interesting tutorial for the transformation of a 3D numerical groundwater flow model done with MODFLOW into a lightweight 2D model. The case of study is a groundwater flow model of tailing seepage done with horizontal discretization from 50 to 12.5m and 21 layers. The tutorial cover spatial object and dataset treatment together with some discussion on the model construction and discretization.

Tutorial: Well Interference Modeling and Interpretation with  MODFLOW

Interesting modeling exercise of groundwater well interference with MODFLOW. This tutorial is made from the ground up with the input files and a discussion over the results. Three pumping were considered with rates form 5 to 10 l/s. Simulation period was set up to 15 years  and interference was analysed over 1, 3, 5,10 and 15 years.
