Code to fit an occupancy model to trapping data for the northwestern pond turtle and red-eared slider in the Sacramento Valley (2018) and Sacramento-San Joaquin River Delta (2019) Code to fit an occupancy model to trapping data for the northwestern pond turtle and red-eared slider in the Sacramento Valley (2018) and Sacramento-San Joaquin River Delta (2019)
Code to reproduce analyses of turtle occupancy in the Sacramento Valley and Sacramento-San Joaquin River Delta
plumeria PMAP software release 1.0.3 plumeria PMAP software release 1.0.3
The PMAP tool is a one-dimensional plume model that predicts ash aggregation within an erupting volcanic plume. The tool was developed by D. W. Hoffman at Stanford, extending from the Plumeria model written by L. G. Mastin at USGS CVO. The code operates using Matlab. The purpose of this repository is to present the code used in the following publication, currently under review at Journal...
Workflow to acquire and process large spatial data and build complex models Workflow to acquire and process large spatial data and build complex models
This software involves R scripts to download and process large-scale spatial data defined by an extent input by the user. The code then resamples data to the desired resolution, downloads metadata from a public website on West Nile virus prevalence in mosquito pools, then extracts spatial layer data as covariates for each record. Also, this software involves R script to fit models of...
GSFLOW: Coupled Groundwater and Surface-Water Flow Model GSFLOW: Coupled Groundwater and Surface-Water Flow Model
Groundwater and Surface-water FLOW (GSFLOW) was developed to simulate coupled groundwater and surface-water resources. The model is based on the integration of the U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) and the U.S. Geological Survey Modular Groundwater Flow Model (MODFLOW).
Analysis of Grass Carp eDNA Data Analysis of Grass Carp eDNA Data
This product contains code to analyze a dataset that was collected to compare a LAMP assay and a qPCR assay for Grass Carp in a pond study. This repository contains the RMarkdown and R files used to analyze the data. It was created to allow for reproducible results. The code assumes the user is experience with R, especially the Tidyverse, and Stan.
