Water Use Site Retrieval - Lower Mississippi Gulf Arkansas Water Use Site Retrieval - Lower Mississippi Gulf Arkansas

In 1977, the Congress of the United States recognized the need for uniform, current, and reliable information on water use and directed the U.S. Geological Survey (USGS) to establish a National Water-Use Information Program (NWUIP) to complement the Survey's data on the availability and quality of the Nations water resources.

WinSLAMM (Source Loading and Management Model): Parameter and standard land-use files for Wisconsin WinSLAMM (Source Loading and Management Model): Parameter and standard land-use files for Wisconsin

The SLAMM model is used to identify sources of pollutants in urban stormwater runoff and to evaluate management alternatives for reduce pollutants. These files provide stormwater flow and pollutant-concentration data for calibrating and verifying SLAMM for use in Wisconsin (WinSLAMM).

Graizer-Kalkan (2015) Ground Motion Prediction Equation Graizer-Kalkan (2015) Ground Motion Prediction Equation

Graizer-Kalkan (2015) ground motion prediction equation (GMPE) is designed to predict peak-ground acceleration and 5% damped pseudo-spectral acceleration response ordinates for shallow-crustal continental earthquakes to be used in earthquake-engineering applications including probabilistic and deterministic seismic hazard analyses.

GWM: Groundwater Management Process for MODFLOW Using Optimization GWM: Groundwater Management Process for MODFLOW Using Optimization

GWM is a Groundwater Management Process for the U.S. Geological Survey modular three-dimensional groundwater model, MODFLOW.

LOLASURVIV LOLASURVIV

Computes estimates of survival and capture probability for open capture-recapture models when sex is not allways known.

GENCAPH1 GENCAPH1

Generates capture-history data for given s,theta,p,c.

HyDroDSS: Hydrologic Drought Decision Support System - Software page HyDroDSS: Hydrologic Drought Decision Support System - Software page

The HyDroDSS is designed to provide water managers with risk-based information for balancing water-supply needs and aquatic-habitat protection goals to mitigate potential effects of hydrologic drought.

Laharz Laharz

Laharz is a Geographical Information Systems tool for automated mapping of lahar inundation hazard zones.

nestAbund nestAbund

An R package to estimate nest abundance using a state-space superpopulation capture-recapture approach in which inference about detection probability is based on the age at first detection, as opposed to the sequence of re-detections in standard capture-recapture models.

SLAMMER SLAMMER

SLAMMER is a Java program that facilitates performing a variety of sliding-block analyses to evaluate seismic slope performance.
