Software

We present software that creates least-cost path spanning trees, a least-cost path minimum spanning tree, and graph theory centrality measures. The software was developed to support identification of population structures--specifically, greater sage-grouse (Centrocercus urophasianus), but also support other species or graph theory applications where least-cost paths are desired. We used...

The Mercury Condition Index Tool uses existing data of mercury concentrations in invertebrates, fish, and birds within national parks to estimate a park level Condition Index (and associated uncertainty) for mercury, based on its potential risk to fish and wildlife health. The tool employs a series of logic steps to convert provided data into standardized units, based upon both basic...

Model Viewer, a graphical user interface for three-dimensional visualization of ground-water results, has been updated to support reading the results from the U.S. Geological Survey’s MODFLOW 6 program. Two examples are included. The example ex-gwf-csub-p04 illustrates the use of the new DIS6 grid format. The second example ex-gwf-disvmesh demonstrates the ability to load and display the...

The code runs a population viability assessment simulation and analyzes the simulated output for Gopher Tortoise Metapopulations in the South Eastern US.

ModelMuse is a graphical user interface for several different groundwater modeling programs. ModelMuse has been updated to generate the input files for the parameter estimation software suite PEST when used with MODFLOW or SUTRA models, run PEST-based parameter estimation, and display the updated model inputs after parameter estimation. The PEST input files can also be used with PEST++...

This version of ModelMuse fixes a serious bug in ModelMuse version 5.1.

ModelMuse version 5.1 updates version 5.0 by adding support for the groundwater transport process and time series files in MODFLOW 6.

MODFLOW 6 - LACP uses the MODFLOW 6.4.0 source code and modifies the Horizontal Flow Barrier (HFB) package to allow simulation of vertical hydraulic conductance (CV) by connection rather than by cell, an option available for previous versions of MODFLOW (USG). The MODFLOW 6 - LACP HFB package is used to simulate thin, vertical, and low-permeability geologic features (barriers) and acts...

The MODFLOW One-Water Hydrologic Flow Model (MF-OWHM) is an integrated hydrologic model designed for the analysis of conjunctive-use management.

MODFLOW-NWT is a Newton-Raphson formulation for MODFLOW-2005 to improve solution of unconfined groundwater-flow problems. MODFLOW-NWT is a standalone program that is intended for solving problems involving drying and rewetting nonlinearities of the unconfined groundwater-flow equation.
