This pipeline analyzes estimates of streamflow, evapotranspiration, soil moisture, and snow water equivalent among other hydrologic states and fluxes from two national hydrologic models: the National Hydrologic Model application of the Precipitation-Runoff Modeling System (NHM-PRMS) and the Weather Research and Forecasting hydrologic modeling system (WRF-Hydro). Both of these models are...

This pipeline uses the data from the 2012 regional Sparrow models (see **Input datasets** below) to produce four types of outputs: 1. Maps of SPARROW-estimated total nitrogen, total phosphorus, and total suspended-sediment yields and concentrations across the conterminous United States (CONUS); 2. Bar plots showing the amount of total nitrogen, total phosphorus, and suspended sediment...

PHREEQC Version 3 is a computer program for speciation, batch-reaction, one-dimensional transport, and inverse geochemical calculations.

PHAST Is a computer program for simulating groundwater flow, solute transport, and multicomponent geochemical reactions.

This software release contains code to process and create pie and bar charts that display high, moderate, and low concentrations of groundwater constituents across principal aquifer locations in the conterminous United States for the National Integrated Water Availability Assessment (IWAAs) Water Quality Chapter. Data are processed from Lindsey et al., 2022 and Belitz et al., 2022. Water...

This software release provides a means of inferring river discharge from remotely sensed data based on critical flow theory. This approach is only applicable to rivers with well defined standing waves and involves measuring their wavelength and the width of the channel. These data are then used to calculate flow velocity, water depth, and river discharge based on an assumption of...

This is the software release of SUTRA version 4.0.0.

SutraSuite is a collection of software for groundwater modeling in both two spatial dimensions (2D) and three spatial dimensions (3D). It includes the SUTRA groundwater model, the SutraGUI pre-processor, the SutraPrep text-based preprocessor, and the SutraPolot post-processor.

There is a need for water professionals to provide water information in maps and graphics that contextualize data for real-time decision-making. hyswap (HYdrologic Surface Water Analysis Package), is a Python package that provides a set of functions for manipulating and visualizing USGS water data. Specifically, a number of functions for calculating statistics (e.g., exceedance...

This pipeline calculates a simple monthly water budget that includes water supply and consumptive use for thermoelectric, irrigation, and public supply for 12-digit Hydrologic Unit Codes (HUC12) across the conterminous United States for water years 2010-2020. Water budget results also include an assessment of supply and use imbalances within the context of historical climatic conditions...

This software release provides a means of inferring the acquisition time of an image using the sundial method. This approach involves measuring the orientation of a shadow on the image and using the calculated solar geometry for that date to identify the time at which the sun would have been positioned so as to cast the observed shadow. The shadow orientation measurement can be made on...

A series of Jupyter notebooks describing the application of uniform manifold approximation and projection (UMAP) to streamflow in hydrologic catchments (examples given for Upper Colorado River Basin) and evaluation of manifolds from modeled and observational data. UMAP produces features that are robust, meaning the resulting images will look similar, even though the underlying data may...
