Thresh - Software for Tracking Rainfall Thresholds for Landslide and Debris Flow Occurrence, Code Repository

The precipitation tracking program, thresh, is a Fortran program designed for computing various measures of precipitation for comparison against established or trial thresholds for landslide occurrence. The program computes cumulative precipitation and precipitation intensity and duration and compares them to thresholds to identify periods of threshold exceedance for use in landslide early warning

USGS StreamStats for Idaho

StreamStats is a Web application that incorporates a Geographic Information System (GIS) to provide users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes.

R code for fitting and simulation study for zero-augmented beta model with errors

Code for implementing the Zero-Augmented Beta Model with Errors (ZABE) , simulation study code, and code for assessing trade-offs in study design via simulations.

ViTexOCR -- a script to extract text overlays from digital video

The ViTexOCR script presents a new method for extracting navigation data from videos with text overlays using optical character recognition (OCR) software. Over the past few decades, it was common for videos recorded during surveys to be overlaid with real-time geographic positioning satellite chyrons including latitude, longitude, date and time, as well as other ancillary data (such as speed, hea

Pedestrian Evacuation Analyst Tool

The Pedestrian Evacuation Analyst is an ArcGIS extension that estimates how long it would take for someone to travel on foot out of a hazardous area that was threatened by a sudden event such as a tsunami, flash flood, or volcanic lahar. It takes into account the elevation changes and the different types of landcover that a person would encounter along the way.

Evolutionary Ecology Software

The programs perform input file formation, distribution visualization, individual-based dynamic population simulation, pedigree accuracy assessment, effective population si

CRT: Cascade Routing Tool to Define and Visualize Flow Paths for Grid-Based Watershed Models

The U.S. Geological Survey Cascade Routing Tool (CRT) is a computer application for watershed models that include the coupled Groundwater and Surface-water FLOW model GSFLOW and the Precipitation-Runoff Modeling System (PRMS). CRT generates output to define cascading surface and shallow subsurface flow paths for grid-based model domains. 

Random Landscape Tool 10.5

Random Landscape Tool uses a raster data source and a table of classifications to create a random landscape. The classification table allows the user to weight the probability of occurrence to certain classes and to spatially restrict the distribution of classes to certain areas (zones).  

nshmp-haz-v1

U.S. Geological Survey (USGS) National Seismic Hazard Mapping Project (NSHMP) code for performing probabilistic seismic hazard (PSHA) and related analyses. These codes are intended for use with seismic hazard models developed by the NSHMP for the U.S. and its territories.

GRIDGEN: A Program for Generating Unstructured Finite-Volume Grids

GRIDGEN is a program for generating layered quadtree grids for MODFLOW-USG.

New York Streamflow Estimation Tool

The New York Streamflow Estimation Tool produces a complete estimated daily mean time series from which daily flow statistics can be estimated and a means for quantitative flow assessments at ungaged locations to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters.
