Modeling Software. The USGS has been a. Multidimensional Surface-Water Modeling System. PHAST is a 3D groundwater flow and solute transport. Software 3D Modelling Geology and Mining. A methodology and associated software tool for 3D geological modelling which enables you to quickly and intuitively.

The Global Climate Change Viewer The Global Climate Change Viewer (GCCV) is used to visualize future temperature and precipitation changes simulated by global climate models in the Coupled Model Intercomparison Project Phase 5 (CMIP5). The application allows the user to visualize projected climate change (temperature and precipitation) for each country, for all available models and all Representative Concentration Pathways (RCP) emission scenarios (2.6, 4.5, 6.0 and 8.5).

ModelMuse ModelMuse is a graphical user interface (GUI) for the U.S. Geological Survey (USGS) models MODFLOW-2005, MODFLOW-LGR, MODFLOW-NWT, MODPATH, ZONEBUDGET, and PHAST and for MT3DMS. This software package provides a GUI for creating the flow and transport input file for PHAST and the input files for MODFLOW-2005.

In ModelMuse, the spatial data for the model are independent of the grid, and the temporal data are independent of the stress periods. Being able to input these data independently allows the user to redefine the spatial and temporal discretization at will. This report describes the basic concepts required to work with ModelMuse. These basic concepts include the model grid, data sets, formulas, objects, the method used to assign values to data sets, and model features. For more information and to download the software. MODFLOW-NWT MODFLOW-NWT, a Newton Formulation for MODFLOW-2005, is a standalone program that is intended for solving problems involving drying and rewetting nonlinearities of the unconfined groundwater-flow equation. MODFLOW-NWT must be used with the Upstream-Weighting (UPW) Package for calculating intercell conductances in a different manner than is done in the Block-Centered Flow (BCF), Layer Property Flow (LPF), or Hydrogeologic-Unit Flow (HUF; Anderman and Hill, 2000) Packages.

PHAST PHAST is a 3D groundwater flow and solute transport model that has extensive capabilities to simulate water-rock and biogeochemical reactions that include all of the reactions available in PHREEQC. Simulations of reactive-transport of are useful for studies of naturally occurring toxic substances, such as selenium and arsenic, and anthropogenic organic and inorganic contaminant plumes. Phast4Windows is a Windows-based, intuitive, 3D graphical user interface for defining model features and execution of PHAST.

For more information and to download the software. PHREEQC PHREEQC is a general purpose geochemical model for reactions in water and between water and rocks and sediments. Reactions include aqueous equilibria, mineral dissolution and precipitation, ion exchange, surface complexation, solid solutions, gas-water equilibrium, and kinetic biogeochemical reactions. PHREEQC has been applied to regional aquifer studies, nuclear waste disposal, carbon sequestration, acid mine drainage, and a multitude of other environments as diverse as paper making, concrete science, and dental research. IPhreeqc and IPhreeqcCOM are interfaces that allow PHREEQC to be implemented in other software. PhreeqcI is a Windows-based user interface that allows defining input, running simulations, and plotting results.

Water, Energy, and Biogeochemical Model (WEBMOD) The Water, Energy, and Biogeochemical Model (WEBMOD) uses the framework of the U.S. Geological Survey (USGS) Modular Modeling System (MMS) to simulate fluxes of water and solutes through watersheds. WEBMOD divides watersheds into model response units (MRU) where fluxes and reactions are simulated for the following eight hillslope reservoir types: canopy; snowpack; ponding on impervious surfaces; O-horizon; two reservoirs in the unsaturated zone, which represent preferential flow and matrix flow; two reservoirs in the saturated zone, which also represent preferential flow and matrix flow.
