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

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.

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...

Automate production of metadata following the USGS geospatial metadata format.

The U.S. Geological Survey Search API is a custom JavaScript library useful for creating a location search widget in a webpage, typically in conjunction with a web map. The widget connects to a database created for the API, or Application-Programming Interface, to quickly find and suggest locations as the user enters text to navigate to areas of interest.

Petroleum resource assessments provide statistical insight into the scale and spatial occurrence of oil and gas accumulations. Similarly, environmental or ecological assessments provide insight into the extent and patterns of ecological resources associated with ecosystems in a region. energySim is an implementation of an approach to link subsurface petroleum resources with ecological...
