Code to assist the USFWS with eDNA field sampling designs for eDNA Code to assist the USFWS with eDNA field sampling designs for eDNA

This code supports the manuscript "Refinement of eDNA as an early monitoring tool at the landscape-level: Study design considerations". The code fit a three-level occupancy model with two detection assays in the program Stan through R. We programmed this code for a specific project with the USFWS and it will likely not generalize to other situations. The primary purpose of releasing this...

Basin Characterization Model (BCM) Basin Characterization Model (BCM)

The Basin Characterization Model (BCM) models the interactions of climate with empirically measured landscape attributes including topography, soils, and underlying geology. It is a grid-based model that calculates the water balance for each 18-acre cell (270m resolution) in a given watershed in set time steps for the entire area.

Coupled-Ocean-Atmosphere-Wave-Sediment Transport (COAWST) Modeling System Coupled-Ocean-Atmosphere-Wave-Sediment Transport (COAWST) Modeling System

The Coupled- Ocean- Atmosphere- Wave- Sediment Transport ( COAWST) Modeling System is an agglomeration of open-source modeling components that has been tailored to investigate coupled processes of the atmosphere, ocean, and waves in the coastal ocean.

An Open Source Spreadsheet for Calculation of Equivalent Freshwater Altitude in Brackish Water Mixing Zone of an Aquifer with Documentation on Appropriate Use An Open Source Spreadsheet for Calculation of Equivalent Freshwater Altitude in Brackish Water Mixing Zone of an Aquifer with Documentation on Appropriate Use

This software release documents an open source spreadsheet that was developed by the USGS in 2007 and modified herein for general use for calculation of equivalent freshwater altitude at wells where the water quality data indicate the well is tapping brackish areas of an aquifer system. One example of this includes coastal wells in the diffusion/mixing or transition zone of the aquifer...

Point-Source Load Estimation Tool (PSLoadEsT) Point-Source Load Estimation Tool (PSLoadEsT)

Software for generating reproducible load calculations for point source dischargers. Includes features to manage common data challenges such as duplicates, incompatible input tables, and missing nutrient concentration or effluent flow data.
