What can MODFLOW be used for?
MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.
What is MODFLOW model?
MODFLOW is the U.S. Geological Survey modular finite-difference flow model, which is a computer code that solves the groundwater flow equation. The program is used by hydrogeologists to simulate the flow of groundwater through aquifers.
Is MODFLOW free software?
Because it’s free and has no charge. MODFLOW, being developed by a public U.S. institution, is distributed freely. There are commercial pre and post interfaces; nevertheless, USGS has developed a high performance pre and post interfase called Model Muse.
What is MODFLOW Surfact?
MODFLOW-SURFACT™ is a powerful 3D finite-difference flow and transport modeling code for analyzing subsurface systems. MODFLOW-SURFACT™ includes advanced computational modules that are based on robust, efficient, mass-conserving algorithms, making it faster and more accurate than its transport modeling counterparts.
How do I run a MODFLOW model?
To run MODFLOW from the command line, you must first open a command line window. In Windows, select Start|Run. Then in the “Run” window, type “cmd” and click OK. In the command line window, you must first navigate to the folder that contains the MODFLOW input files.
Who developed MODFLOW?
Visual MODFLOW (VMOD) is a graphical interface (GUI) for the open source groundwater modeling engine MODFLOW. VMOD was developed by Waterloo Hydrogeologic and first released in 1994, the first commercially available GUI for MODFLOW.
How do I download MODFLOW software?
This software package can be downloaded from the website “http://water.usgs.gov/ogw/mod- flow/MODFLOW. html#downloads“. Navigate to this site and click on “MODFLOW-2005 v. 1.11.
What is groundwater model calibration?
A model that is “calibrated” is required to address many hydrologic problems. Model calibration in its most limited meaning is the modification of model input data for the purpose of making the model more closely match observed heads and flows.
How do you cite a MODFLOW?
Report Citation for MODFLOW-2005 Harbaugh, A.W., 2005, MODFLOW-2005, the U.S. Geological Survey modular ground-water model — the Ground-Water Flow Process: U.S. Geological Survey Techniques and Methods 6-A16.
What is a groundwater flow model?
A groundwater flow model is a mathematical representation of groundwater flow through an aquifer, which is composed of saturated sediment and rock. models integrate and assure consistency among aquifer properties, recharge, discharge, and groundwater levels.
What is Visual MODFLOW Flex?
Built and designed on the latest in 3D visualization technology, Visual MODFLOW Flex allows you to effectively present and communicate your data to colleagues and stakeholders with impressive visual renderings of your hydrogeologic model.
What is a MODFLOW model?
MODFLOW is a popular open-source groundwater flow model distributed by the U.S. Geological Survey. Growing interest in surface and groundwater interactions, local refinement with nested and unstructured grids, karst groundwater flow, solute transport, and saltwater intrusion, has led to the development of numerous MODFLOW versions.
Where can I find a MODFLOW-2005 user guide?
The MODFLOW-2005 guide can be found online. An online guide is not presently available for MODFLOW 6; an up-to-date user guide is included in the MODFLOW 6 distribution. Successful use of MODFLOW typically requires a college-level modeling course or professional training on groundwater modeling.
Can I visualize groundwater-flow model results in visit?
i’ve seen a couple of mentions ( like this one) to the VisIt user forum regarding visualizing groundwater-flow model results in VisIt. while there are many options to visualize the input and output data from a MODFLOW groundwater-flow model, here we’re going to explore one that uses the VTK file format.
