Visualizations of water quality across the conterminous United States using SPARROW 2012 simulated nutrient load estimates Visualizations of water quality across the conterminous United States using SPARROW 2012 simulated nutrient load estimates
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...
Climate-driven declines in fish abundance workflow and analysis Climate-driven declines in fish abundance workflow and analysis
This repository provides the necessary R and stan scripts to fit a joint species, spatially dependent physiologically guided abundance (jsPGA) model (Custer et al. 2024) to fishes from over 11,000 Midwestern US lakes in an effort to predict the effects of climate change on their abundance, distributions, and extirpation probabilities.
Atlas of Breeding Sites for Waterbirds in the Northern Gulf of America Atlas of Breeding Sites for Waterbirds in the Northern Gulf of America
The Atlas of Breeding Sites for Waterbirds in the Northern Gulf of America is an effort to map the breeding locations of coastal breeding waterbirds in the northern Gulf of America from 2010-2022. The Atlas was developed to provide stakeholders in the region with a means to readily access the location and status (both recent and current) of sites used for breeding activities by a wide...
Code for Missouri Stream Conservation and Connectivity Prioritization Tool: Improving and Expanding Existing Conservation Networks Code for Missouri Stream Conservation and Connectivity Prioritization Tool: Improving and Expanding Existing Conservation Networks
The Missouri Stream Conservation and Connectivity Prioritization Tool can be used to identify the number and nature of barriers to fish movement between stream reaches. This data can be used to target stream reaches for protection, conservation, and reestablishing connectivity within and between existing conservation networks. The tool allows users to select a subset of stream reaches...
Socioeconomic effects of bison and elk management alternatives on National Elk Refuge Socioeconomic effects of bison and elk management alternatives on National Elk Refuge
The purpose of this software is to develop predictions about future changes in the social and economic benefits provided by bison and elk and their management on the National Elk Refuge. The effects are estimated as a function of changing wildlife populations under different management alternatives. For additional detail on the methodology and case study, please refer to: McEachran, M.C...

Evaluating high, moderate, and low concentrations of groundwater constituents across principal aquifer locations in the conterminous United States Evaluating high, moderate, and low concentrations of groundwater constituents across principal aquifer locations in the conterminous United States
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...
critFlowQ critFlowQ
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...
SUTRA 4.0.0 SUTRA 4.0.0
This is the software release of SUTRA version 4.0.0.
SUTRA: A Model for 2D or 3D Saturated-Unsaturated, Variable-Density Ground-Water Flow With Solute or Energy Transport SUTRA: A Model for 2D or 3D Saturated-Unsaturated, Variable-Density Ground-Water Flow With Solute or Energy Transport
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.
