This standalone software application provides an integrated set of tools for inferring river discharge Q from remotely sensed data based on critical flow theory, a method introduced by Legleiter et al. (2025). This approach can yield accurate streamflow estimates in rivers with well-defined standing wave trains, referred to as undular hydraulic jumps (UHJ's). Once an image with clearly...

SURF is an algorithm to generate 3D fault models. This algorithm utilizes open-source, well known and documented packages, to generate fault models that require very few user input parameters.

Land managers seek to understand whether treatments they implement effectively achieve their goals to support, or at least not negatively impact, species of concern. This power analysis identifies minimum data collection needs to estimate treatment impacts when baseline species community information is lacking, and when there is significant risk of violating the species exchangeability...

This code uses Nimble to run a Bayesian hierarchical model using both linear and nonlinear features. The model assesses the effects of various changes in white-tailed deer (Odocoileus virginianus) harvest regulations on realized annual antlerless harvest. Eight states participated in this analysis and all data was unified to a common definition through extensive consultation with experts...

ezMCDA is a user-friendly software to conduct Multicriteria Decision Analysis (MCDA) while considering uncertainty and nonlinear utility functions.

This product is a series of Jupyter Notebook tutorials that are designed to help researchers preprocess data and statistically compare modelled and observational precipitation, temperature, and radiation data. The first notebook walks researchers through setting up their environment, important concepts, querying data sources, and filtering their data to the same temporal and spatial...

The Articulated Barrier Shoreface (ABSF) Model is a framework to simulate the transgression of a barrier island under sea-level rise, including a dynamic upper (US) and lower (LS) shoreface and overwash components. The model is written in MATLAB and in python, both versions included in this release.

Code for implementation of the Dynamic Surface Water Extent algorithm in Google Earth Engine. Multiple scripts allow the creation of single-scene or composited Dynamic Surface Water Extent (DSWE) images from Landsat (updated for Collection 2 imagery) and MODIS data. All code is written for use in Google Earth Engine in the JavaScript API.

This script simulates data under an example scenario and applies a model to the simulated dataset to estimate trend, thus evaluating the power to detect the trend. The study was designed to evaluate various scenarios (sampling designs, as well as biological parameters that differ between the two study lagoons).

The Export Helper is a GUI tool designed to be embedded in the Agisoft Metashape application for flexible automation of batch exports.

D-Claw is a software library for the simulation of dense granular flows over spatially variable topography. D-Claw builds on clawpack, is written in Fortran, and has a python wrapper. The code is hosted on code.usgs.gov and mirrored on github. D-Claw is supported on Linux/Unix only.

This repository provides the R scripts and stan files to fit hierarchical logistic regression models, using a regularized horseshoe prior on regression coefficients, to examine spatial drivers of DELT occurrence in fishes in the Chesapeake Bay Watershed, USA.
