Peak Flow Frequency R EXtensions Peak Flow Frequency R EXtensions

R tools to assist with peak-flow frequency analysis using the USGS PeakFQ software.

National Streamflow Statistics (NSS) Application National Streamflow Statistics (NSS) Application

The National Streamflow Statistics (NSS) Application is an online computer application that provides a simple method for applying regional flood-peak streamflow estimates and low flow frequency/duration streamflow estimates.

ObsNetQW---Assessment of a water-quality aquifer monitoring network ObsNetQW---Assessment of a water-quality aquifer monitoring network

The establishment of an efficient aquifer water-quality aquifer monitoring network is a critical component in the assessment and protection of groundwater quality. A periodic evaluation of the monitoring network is mandatory to ensure effective data collection and possible redesigning of existing network. This package assesses the efficacy and appropriateness of an existing water-quality...

Reston Stable Isotope Lab Laboratory Information Management System (LIMS) for Lasers & Light Stable Isotopes Reston Stable Isotope Lab Laboratory Information Management System (LIMS) for Lasers & Light Stable Isotopes

The Reston Stable Isotope Laboratory LIMS (Laboratory Information Management System) software suite is available for download: 1) LIMS for Lasers 2015 for off-axis and cavity ring-down laser absorption spectrometers, 2) LIMS Data Viewer, a companion utility that allows read-only access to LIMS for Lasers data, and 3) LIMS for Light Stable Isotopes for isotope-ratio mass spectrometers.

mapRandomForest---Monthly flow estimation in the Mississippi Alluvial Plain by means of Random Forest Modeling mapRandomForest---Monthly flow estimation in the Mississippi Alluvial Plain by means of Random Forest Modeling

The code included in this package, when combined with data retrieved from an associated ScienceBase archive, is designed to allow for reasonable monthly total and baseflow volumes to be estimated at arbitrary locations within the Mississippi Embayment as part of the Mississippi Alluvial Plain (MAP) Project. The resulting surface water volume estimates were used as inputs to associated...

grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases

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...

Multi-grid Analysis of Point Stability Tool Multi-grid Analysis of Point Stability Tool

Elevation-change datasets can also be used to identify stable and unstable areas of the seafloor. The Multi-grid Analysis of Point Stability (MAPS) program was created to automate this process. This program is used to locate persistent areas of user-defined seafloor stability and/or instability at common geographic locations from multiple elevation-change datasets (grids) representing...

MetaIPM MetaIPM

MetaIPM is a Python package (Python Software Foundation 2020) that models meta-population dynamics and continuous growth rates via an integral projection model (IPM) for species living in distinct habitat patches. The package stems from a model that compares invasive carp population control strategies. The package supports differing sex and any organisms living in distinct habitat...

gfail_lifelines gfail_lifelines

gfail_lifelines is a package for estimating lifeline impacts caused by earthquake-triggered ground failure. It currently contains one module, gfroads, that combines the USGS earthquake-triggered landslide model (the Nowicki Jessee et al. 2017 model) estimates of areal coverage with Open Street Map roads to estimate the probability of a given road segment being affected.

Stochastic Empirical Loading and Dilution Model (SELDM) software archive Stochastic Empirical Loading and Dilution Model (SELDM) software archive

The Stochastic Empirical Loading and Dilution Model (SELDM) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to transform complex scientific data into meaningful information about the risk of adverse effects of runoff on receiving waters, the potential need for mitigation...
