SeismoTectonic Regime Earthquake Calculator (STREC)

Automatically determines the earthquake type (subduction zone interface, active crustal shallow, stable continental region, etc.) and the earthquake focal mechanism.

Composite Raster and Divergence Tool

ArcGIS ArcMap add-in, when using this tool, a user can: 1) create a date prioritized composite raster from a collection of raster layers 2) create a lookup raster for the composite raster that identifies which input layers were used to create the composite raster 3) create a divergence raster where pixel values represent the divergence from a user specified value

Composite Raster and Divergence Tool

The Composite Raster and Divergence Tool is an ArcGIS ArcMap add-in

SPARROW modeling: Estimating contaminant transport

SPARROW (SPAtially Referenced Regression On Watershed attributes) models estimate the amount of a contaminant transported from inland watersheds to larger water bodies by linking monitoring data with information on watershed characteristics and contaminant sources.

Chemical Mixtures Software

The chemical mixtures software is a collection of computer programs for investigating the composition, occurrence, distribution, and potential toxicity of chemical mixtures.  The software is designed to assist with selecting specific mixtures for future research, identifying the causes for the occurrence of specific mixtures, and discovering the effects of mixtures. 

MODPATH: A Particle-Tracking Model for MODFLOW

MODPATH is a particle-tracking post-processing model that computes flow paths using output from MODFLOW.

Metadata Wizard

The MetadataWizard is a useful tool designed to facilitate FGDC metadata creation for spatial and non-spatial data sets.

fatalityCMR

Capture-recapture software to correct raw counts of wildlife fatalities using trial experiments for carcass detecition probability and persistence time.

CE-QUAL-W2 - Hydrodynamic and Water Quality Model

CE-QUAL-W2 is a water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic eutrophication processes such as temperature-nutrient-algae-dissolved oxygen-organic matter and sediment relationships.

MODFLOW-USG: An Unstructured Grid Version of MODFLOW for Simulating Groundwater Flow and Tightly Coupled Processes Using a Control Volume Finite-Difference Formulation

MODFLOW-USG is an unstructured grid version of MODFLOW for simulating groundwater flow and tightly-coupled processes using a control volume finite-difference formulation.

eDNAoccupancy

This repository contains the source code and package for the eDNAoccupancy package. This readme file contains the installation instructions for the package. The purpose of the R package is to fit three-level occupancy models. Although designed with eDNA-based observations, the package can be used for any occupancy situation with sampling and sub-sampling.

landslides-mLS

mLS is a function that estimates the landslide magnitude (mLS) from cutoff (smallest area that follows power law), beta (power-law exponent), and an array of areas derived from a landslide inventory following the methods of Tanyas and others (in prep). The function plots the best power-law fit for the medium and large landslides and the frequency-area distribution of the analyzed inventory. It als
