Numerical model of coastal Erosion by Waves and Transgressive Scarps (NEWTS) Numerical model of coastal Erosion by Waves and Transgressive Scarps (NEWTS)
The Numerical model of coastal Erosion by Waves and Transgressive Scarps (NEWTS) model is a framework to simulate the erosion of a closed-basin coastline through time by fetch-dependent erosion or uniform erosion. The model is written in MATLAB and the MATLAB Image Processing Toolbox and a MEX compiler are required.
Chronic Wasting Disease Surveillance Optimization Software Version 2 Chronic Wasting Disease Surveillance Optimization Software Version 2
The Chronic Wasting Disease Surveillance Optimization Software Version 2 computes sampling recommendations to detect chronic wasting disease (CWD) in white-tailed deer (Odocoileus virginianus). Driven by a combinatorial optimization algorithm, the software maximizes the return-on-investment to the wildlife agency while keeping the overall surveillance program within budget. The software...
Chronic Wasting Disease Modeling for Bridger Teton National Forest Structured Decision Making (cwd-btnf-sdm-v2) Chronic Wasting Disease Modeling for Bridger Teton National Forest Structured Decision Making (cwd-btnf-sdm-v2)
This software release contains the code necessary to run the chronic wasting disease (CWD) and elk habitat selection models used to support the U.S. Forest Service decision on whether to continue to permit supplemental feeding of elk on USFS land. The models allow for four different management alternatives: continued feeding, emergency feeding, phase-out after three years, or no feeding...
Optimal harvest of a theoretical population under system change Optimal harvest of a theoretical population under system change
This code solves optimal harvest policies under different scenarios of system change, represented as changes in demographic parameters over time. This document contains code to solve policies using backwards iteration stochastic dynamic programming, project populations forward to simulate the policies, and generate figures.
R Code Supporting the Manuscript: Using Stochastic Point Pattern Analysis to Track Regional Orientations of Magmatism During the Transition to Cenozoic Extension and Rio Grande Rifting, Southern Rocky Mountains R Code Supporting the Manuscript: Using Stochastic Point Pattern Analysis to Track Regional Orientations of Magmatism During the Transition to Cenozoic Extension and Rio Grande Rifting, Southern Rocky Mountains
This repository contains code that supports ongoing research in the southern Rocky Mountains in Colorado and northern New Mexico. This region hosted intracontinental magmatism that developed during a tectonic transition from shortening (Laramide orogeny, ca. 75 to 40 Ma) through extension and rifting. The code in this repository presents a novel approach that uses stochastic weighted...
SAS: Software Application for SMASH (Spectral Mixture Analysis for Surveillance of Harmful Algal Blooms) SAS: Software Application for SMASH (Spectral Mixture Analysis for Surveillance of Harmful Algal Blooms)
The Software Application for SMASH (Spectral Mixture Analysis for Surveillance of Harmful Algal Blooms), or SAS for short, is an application to facilitate mapping of potentially harmful algal blooms in reservoirs, rivers, and lakes from remotely sensed data. More specifically, SAS is designed to exploit the detailed observations of reflectance available within a hyperspectral image to...
