-R code to create and fit dynamic occupancy models to Dixie Valley Toad survey data in JAGS and produce useful summaries of model results. This script will perform the Gibbs Variable Selection (GVS) using the initial set of environmental covariates, and then fit the "final" model using only important environmental covariates. The dynamic occupancy model is adapted from the model...

The covMRVAgen1 repository contains R (primarily), Mermaid, Perl, and Python language source code that can be used the construction of input tables of monthly groundwater levels (response variable) and predictor variables (covariates) for statistical modeling of water levels in the Mississippi River Valley alluvial aquifer within the Mississippi Alluvial Plain, south-central United...

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.

This is a repository with R code for CWD simulation models and interactive Shiny applications. Currently there are deterministic and stochastic models that are intended to model hunting scenarios for a 5 to 10 year time horizon. The models are sex and age structured with direct and indirect transmission.

The U.S. Geological Survey (USGS) developed an R package called dataRetrieval to help simplify the process of discovering and retrieving water quality sample data, streamflow, groundwater, and other data available from Federal hydrologic web services such as National Water Information Systems (NWIS), the EPA Water Quality Exchange (WQX) System, and the National Hydrologic Dataset via the...

Estimating the number of birds or bats killed at a wind power facility involves adjusting observed carcass counts to account for imperfect detection. To account for carcasses that lie outside the searched area, the count is adjusted by dividing by the estimated proportion of carcasses lying within the searched area or the density-weighted proportion (dwp). The dwp package provides tools...

Did You Feel It? (DYFI) collects information from people who felt an earthquake and creates maps that show what people experienced and the extent of damage.

This application was created to visualize and interact with the ecological data from the ongoing monitoring effort on two previously restored streams in Reston, Virginia - Snakeden Branch and The Glade. The “Reston monitoring program” includes the measurement of hydrologic, water-quality, and ecological data and evaluations of changes in these measurements over time. For more information...

The Gage Statistic (GageStats) Services were developed to provide gage characteristics and streamflow statistics to support the StreamStats application via RESTful principles. The StreamStats application uses GageStats Services to display the gages and related gage pages. These services provide U.S. Geological Survey developed and published gage characteristics such as drainage area or...

The Interagency Flood Risk Management (InFRM) team’s Flood Decision Support Toolbox is designed to accept flood map library submission from external agencies wishing to contribute to the web application. The geoprocessing of geospatial data comprising the flood map libraries follows set guidelines to facilitate the submission process to the web application. However, the InFRM team...

This tool is being provided free to the public in support of GIS specialists who calculate summary information.

Greater sage-grouse (Centrocercus urophasianus) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the western United States. They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great Plains of the United States. Sage-grouse are one of the most...
