Software

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.
