Science-based Management of Ravens Tool (SMaRT) Science-based Management of Ravens Tool (SMaRT)
The Science-based Management of Ravens Tool (SMaRT) supports a science-based adaptive management framework that incorporates recent quantitative analyses and mapping products for addressing areas with elevated common raven (Corvus corax) numbers and minimizing potential adverse impacts to sensitive species, agricultural damage, and human safety (Dettenmaier et al. 2021). This is a web...
Code to analyze Capture-Mark-Recapture data of San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) Code to analyze Capture-Mark-Recapture data of San Francisco gartersnakes (Thamnophis sirtalis tetrataenia)
Code files "growth_analysis.R" -An R script to fit the von Bertalanffy growth model to growth data from San Francisco gartersnakes. The von Bertalanffy growth model is fit using JAGS software (Plummer 2003), and is based on the model presented in Armstrong and Brooks (2013). "survival_analysis.R" -An R script to fit the robust-design Cormack-Jolly-Seber model to capture-mark-recapture...

GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool
The Groundwater/Surface-Water Method Selection Tool (GW/SW-MST) is a spreadsheet-based tool to help practitioners identify methods for use in groundwater/surface-water (GW/SW) exchange and hyporheic studies. GW/SW exchange and hyporheic processes are topics receiving increasing attention from the hydrologic community. Hydraulic, chemical, temperature, geophysical, and remote sensing...
MODFLOW-NWT: A Newton Formulation for MODFLOW-2005 MODFLOW-NWT: A Newton Formulation for MODFLOW-2005
MODFLOW-NWT is a Newton-Raphson formulation for MODFLOW-2005 to improve solution of unconfined groundwater-flow problems. MODFLOW-NWT is a standalone program that is intended for solving problems involving drying and rewetting nonlinearities of the unconfined groundwater-flow equation.
