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...
