QRev 4
QRev is a software package for processing streamflow measurements made using an acoustic Doppler current profiler (ADCP) from a moving-boat. QRev was developed by the USGS to provide for more consistent review of ADCP discharge measurements and to gain efficiency. QRev supports both SonTek and Teledyne RD Instruments ADCPs.
ORByT - Optical River Bathymetry Toolkit
The Optical River Bathymetry Toolkit, ORByT, is an application to facilitate mapping water depth in river channels from passive optical image data. ORByT provides an integrated workflow for image processing, depth retrieval, and export of results.
StreamStats Data Preparation Tools, version 4
A Python package to pre-process and hydro-enforce digital elevation models using hydrography features for use in the U.S. Geological Survey (USGS) StreamStats project.
Annual Management Unit Summary Code
The Phragmites Adaptive Management Framework (PAMF) is an adaptive management program created to improve the efficacy and efficiency of Phragmites management efforts throughout the Great Lakes region. Managers enroll Phragmites stands, report the management techniques they used, and monitor the invasion status of Phragmites on their site (management unit - MU). Through a systematic approach, PAMF
QRev
The software program, QRev, written in Python, computes the discharge from moving-boat ADCP measurements using data collected with any of the Teledyne RD Instrument (TRDI) or SonTek bottom tracking ADCPs. The computation of discharge is independent of the manufacturer of the ADCP because QRev applies consistent algorithms independent of the data source. In addition, QRev automates filtering and qu
DTSGUI
DTSGUI is a public-domain software tool to import, manage, parse/cull, georeference, analyze and visualize fiber-optic distributed temperature sensor (FO-DTS) data. Visualization can efficiently be accomplished in the form of heat maps of temperature (as color) versus distance and time, and in map view plots of georeferenced data on land-surface orthoimagery. The code is written in object-oriented
Precipitation Runoff Modeling System (PRMS) version 5.1.0
The need to assess the effects of variability in climate, biota, geology, and human activities on water availability and flow can be assessed with computer models that simulate the hydrologic cycle at a watershed scale. The Precipitation-Runoff Modeling System (PRMS) is a deterministic, distributed-parameter; physical process-based modeling system developed to evaluate the response of various comb
Summarize raster layers within overlapping polygons
Python code generated for the purpose of summarizing a defined set of discrete/categorical and/or continuous raster layers within zones that may be overlapping. Many widely used GIS tools to summarize raster layers within zones are not capable of handling overlapping zones. This code also allows for the computations to be completed over a number of separate raster layers at once and compiles the o
Software for the analytical code PAT (Purge Analyzer Tool) for computation of in-well time of travel of groundwater under pumping conditions
Purge Analyzer Tool - For computation of in-well time of travel of groundwater under pumping conditions.
RESTORE/fdclmrpplo, Source code for estimation of L-moments and percent no-flow conditions for decadal flow-duration curves and estimation at level-12 hydrologic unit codes along with other statistical computations
The RESTORE/fdclmrpplo repository contains R language source code used for estimation of the L-moments and percent no-flow conditions (no-flow fractions) for decadal flow-duration curves and estimation at streamgages and level-12 hydrologic unit codes using generalized additive models and censored generalized additive models. The source code is designed to streamline the workflow for the Gulf Coas
PRMS version 5.0.0: Precipitation-Runoff Modeling System
The need to assess the effects of variability in climate, biota, geology, and human activities on water availability and flow requires computer models that simulate the hydrologic cycle at a watershed scale. The Precipitation-Runoff Modeling System (PRMS) is a deterministic, distributed-parameter; physical process based modeling system developed to evaluate the response of various combinations of
GSFLOW: Coupled Groundwater and Surface-Water Flow Model, version 2.1.0
GSFLOW is a coupled Groundwater and Surface-water FLOW model based on the integration of the USGS Precipitation-Runoff Modeling System (PRMS-V) and the USGS Modular Groundwater Flow Model (MODFLOW-2005 and MODFLOW-NWT). GSFLOW was developed to simulate coupled groundwater/surface-water flow in one or more watersheds by simultaneously simulating flow across the land surface, within subsurface satur
