This repository contains R scripts, YAML files, and BASH code to run simulations and evaluate the case study described in "Evaluating alternative methods for modeling trap efficiencies of outmigrating juvenile salmonids" (Walden and Som 2026), and depends on data files available in the accompanying data release https://doi.org/10.5066/P1PN4IHO. The R scripts can be run directly in R (instructions below) or can be used with the YAML files and BASH commands to run the simulations on a supercomputing cluster.
