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.

MODFLOW is a popular open-source groundwater flow model distributed by the U.S. Geological Survey.

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...

This software was used to make derivatives of the features in the NHDPlusV2 geospatial dataset for use in hydrologic model applications. It is not intended for users to deploy/use and may produce unexpected results outside the workflow and environment in which it was implemented. For users seeking to deploy a version of this software, please see https://github.com/noaa-owp/hydrofab. The...

ModelMuse is a graphical user interface (GUI) for the U.S. Geological Survey (USGS) models MODFLOW 6, MODFLOW–2005, MODFLOW-LGR, MODFLOW-LGR2, MODFLOW-NWT, MODFLOW-CFP, MODFLOW-OWHM versions 1 and 2, MODPATH, ZONEBUDGET, PHAST, SUTRA 2.2, SUTRA 3.0, SUTRA 4.0, MT3D-USGS, and WellFootprint and the non-USGS programs MT3DMS and PEST.

This software release contains code to create the fractional intersectional weights used to crosswalk data from the National Water Use Program to the National Integrated Water Availability Assessment (IWAAs) projects. The Watershed Boundary Dataset (WBD) contains polygons that define the spatial boundaries of hydrologic units. These are periodically updated as these boundary definitions...
