The United States Geological Survey (USGS) has just released a new MODFLOW version: MODFLOW-6. This one comes with new functionalities to make it easier to create input files and perform simulations. Among the downloaded MODFLOW-6 files, there is an executable file to convert MODFLOW-2005 files to the new MODFLOW-6 format. In this tutorial we will show you how to do this.

Read MoreMODFLOW is a versatil and applied computer code written in Fortran capable of modeling groundwater flow on steady and transient conditions. MODFLOW can simulate a diverse sort of groundwater flow management cases due to its packages and solvers. This tutorial shows the application of MODFLOW for the simulation of radial drains in a mine tailings facility. The simulation considers 16 drains of 60 m length over a simulation period of 1000 days.
Read MoreNowadays, water resources management requires a better understanding of nature and a superior evaluation of the impacts caused by humans. We are concerned and focused on sustainability because we live on a planet with limited resources and changing environments. In some way, we know that the actual changes are results from past and present actions along with the effect of nature cycles.
Read MoreIf we want to talk about concentrations, solutes and contaminant transport in groundwater, we need to mention the Source/Sink concepts and natural concentrations in groundwater. Sources represent solute mass entering the system, which could be representing spills or natural lixiviation processes. Sinks are the zones where water with solute concentrations leave the system.

Read MoreInteresting 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.
Read MoreInteresting 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.
Read MoreContinue 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.
Read MoreMODFLOW 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.
Read MoreGroundwater modelling can be done on multiple temporal and spatial scales, from a laboratory setup to a complete basin, from steady-state to thousands of years. Each modelling requirement has a specific discretization and boundary condition setup. This tutorial cover a regional groundwater modelling example on a andean basin on steady state conditions, the tutorial covers the whole set of modelling steps as grid generation and elevation import as well as the model simulation and result evaluation. Numerical modelling was done in open source software as MODFLOW with Model Muse, both developed by the USGS.
