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.

USGS developed, in cooperation with the Office of Surface Mining Reclamation and Enforcement, “user-friendly” aqueous geochemical modeling tools to simulate changes in water quality during passive and active treatment of acid mine drainage.

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...

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.

Understanding how data are used across the scientific community provides many benefits to data authors, including building a better awareness and comprehension of 1) a dataset's scientific impact, 2) use cases to direct future versions, and 3) related efforts. Effectively tracking when and how data are used in the literature through time can be challenging. This is in part due to a lack...

The Python GIS Flood Tool (pygft) was designed to process stream, catchment, and elevation datasets in order to assess the extent and depth of flooding for each stream reach. The model itself is light-weight, created with the capability to scale to larger regions or CONUS (conterminous United States) scales.

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...

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.

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...

In cooperation with StreamStats, the runoff modeling services were developed using RESTful principles in order to assist engineers and watershed managers by calculating peak runoff for small watersheds.
