Version 2.3.0 of Coupled Ground-Water and Surface-Water Flow Model Based on the Integration of the Precipitation-Runoff Modeling System (PRMS) and the Modular Ground-Water Flow Model Version 2.3.0 of Coupled Ground-Water and Surface-Water Flow Model Based on the Integration of the Precipitation-Runoff Modeling System (PRMS) and the Modular Ground-Water Flow Model

GSFLOW is a coupled Groundwater and Surface-Water Flow model based on the integration of the U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS; Markstrom and others, 2015) and the U.S. Geological Survey Modular Groundwater Flow Model (MODFLOW-2005, Harbaugh, 2005; MODFLOW-NWT, Niswonger and others, 2011). In addition to the basic PRMS and MODFLOW simulation methods...

Code for: Leveraging local efforts to solve regional-scale ecological questions: using multiple sources of data and a multi-species occupancy model to explore bee-plant interactions Code for: Leveraging local efforts to solve regional-scale ecological questions: using multiple sources of data and a multi-species occupancy model to explore bee-plant interactions

This repository contains all of the scripts to reproduce the analyses, figures, and tables associated with the manuscript Lee et al. in prep. The scripts are organized in the order in which they should be run. Briefly, the files do the following: format the data, fit the model, create the figures, and create the tables.

UASmagpy: Python code for compensating rotary-wing sling-load UAS aeromagnetic data UASmagpy: Python code for compensating rotary-wing sling-load UAS aeromagnetic data

This notebook implements the processing of UAS aeromagnetic total magnetic intensity data as described in Phelps and others (2022). After low-pass filtering the raw data and applying a diurnal magnetic correction, a heading and altitude correction model is applied to the data, solved using regularized regression methods; heading refers to the direction in which the sensor is flying. The...

DataRetrieval.jl DataRetrieval.jl

DataRetrieval.jl is a Julia alternative to the R dataRetrieval package for obtaining USGS water data directly from web services.

Coregonid Coregonid

This repository contains code for the analysis from a study that examined mortality and qPCR detection in 4 groups of fish: an uninfected control group, an infected control group, and two treatment groups. The main goals were to determine if their were differences in mortality and qPCR detection of the parasite among the differing groups. Mortality was addressed using a Generalized...

Software for SIR 'Effect of Data Pooling on Predictions From the Three-Part Method for Quantitative Mineral Resource Assessment-An Investigation of a Previous U.S. Geological Survey Assessment' Software for SIR 'Effect of Data Pooling on Predictions From the Three-Part Method for Quantitative Mineral Resource Assessment-An Investigation of a Previous U.S. Geological Survey Assessment'

The Three-Part Method for Quantitative Mineral Resource Assessment has been used by the USGS to predict mineral resources since at least 1975. These predictions use pooled data, and the effects of the pooling on the predictions is investigated and reported in the forthcoming USGS publication. The calculations and figures for this report are performed with software that will be...
