U.S. Geological Survey (USGS) National Seismic Hazard Model Project (NSHMP) codes for performing probabilistic seismic hazard (PSHA) and related analyses. These codes are intended for use with seismic hazard models developed by the NSHMP for the U.S. and its territories. This project includes a variety of command line applications and web service classes and relies on the nshmp-lib...

nshmp-lib is a USGS developed Java library that supports probabilistic seismic hazard (PSHA) and related analyses. This project includes all the code required to load, process and query USGS National Seismic Hazard Models (NSHMs). nshmp-lib is used by command line applications and web services found in the nshmp-haz project. See that project for running PSHA calculations.

R-based script used to simulate patterns of co-occurrence among two hypothetical species under patterns of avoidance, aggregation, and independence when the closure assumption is met or not, analyze simulated patterns with two-species occupancy models, and summarize the results.

The ToxMixtures R-package includes a set of functions to analyze, visualize, and organize measured chemical concentration data as it relates to chemical mixtures. ToxMixtures combines outputs from the R-package toxEval with open access sources on molecular biology to provide information on potential biological effects of chemicals detected in environmental matrices. To use ToxMixtures...

The culvert analysis program (CAP) version 2021 updates and corrects know errors in standalone versions 98-07c or earlier and iRIC version 3.X or earlier.

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...
