/The MODFLOW SUB-WT code has been developed to simulate vertical compaction in regional groundwater flow models due to pumping.
MODFLOW SUB-WT can simulate changes in groundwater storages and compaction in discontinuous layers or extensive confining units. The MODFLOW SUB-WT modeling code considers the compaction of a particular layer of the numerical model as a function of effective effort changes in the layer.

/When I was in second semester of my master degree, the course director gave me this advice: “Learn MODFLOW and you will have a job”. That was a small and sincere advice that helped me on the last eight years as hydrogeologist – numerical modeler. Nowadays, I want to give the guidelines for people interested in how to be a senior hydrogeologist in 6 years.
Read MoreWhy is MODFLOW better than other softwares for groundwater modelling?
/MODFLOW is the groundwater modelling software developed by the U.S. Geological Survey (USGS). It appeared in 1984 and has had a constant developement till now. MODFLOW’s capacities allow the representation of regional or local groundwater flow and its interaction with superficial water bodies.
Read MoreOverview of the “Radius of Influence”
/Since an homogenous aquifer was modelled, there is an interest in comparing the results with an analytical solution. Some formulas give the drawdown value into the well for a steady flow in confined and unconfined aquifers that are homogeneous, isotropic and infinite in the horizontal extent with a single full penetrating well.

/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.
Read MoreMain factors affecting groundwater regime
/The concept of a groundwater regime is based on the fact that the occurrence and distribution of groundwater is not merely a product of chance, but the result of a combination of climatic, hydrologic, geologic, topographic and soil-forming factors that together form an integrated dynamic system. These factors are interrelated in such a way that each provides some insight into the functioning of the total system and thus serves as an indicator of local conditions of groundwater occurrence and distribution (PAEL, 1993).
Read MoreMain predictive simulations for an EIA in mining
/Impact assessment of mining projects on groundwater resources can be a challenging task due to uncertainty on groundwater flow regime, the complex numerical tools to successfully simulate stresses on groundwater resources posed by the mining projects, timeframe and budget of EIAs.
In this article, we will call EIA the document issued before the mine begins for regulatory official approval and social license.

/MODFLOW-CFP is an efficient tool that helps us to model karstic conduits and learn about their interaction with groundwater flow.
Read MoreRegional Groundwater Modeling with MODFLOW and Model Muse
/Groundwater 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.
