Abstract

This resource contains the inputs and outputs for soil erosion and runoff models using the Water Erosion Prediction Project (WEPP). The simulations cover 3 HUC12 watersheds within or near the Minnesota counties of Dodge, Goodhue, and Stearns for 3 separate time periods: 1965-2019, 2020-2059, and 2060-2099. Two CMIP5 climate models (GFDL-ESM2G and HadGEM2-CC) were used to generate the WEPP climate inputs, and two relative concentration pathway (RCP) scenarios were used for each model. The WEPP management, slope, and soil inputs were provided by Daryl Herzmann and Brian Gelder from the Daily Erosion Project (DEP) at Iowa State University. The management input files were edited to include a number of different adoption rate scenarios for perennial crops, cover crops, and reduced tillage systems. These datasets are part of a master's thesis project conducted by Garner Kohrell (student) and Dr. David Mulla (Advisor). The chapters of this thesis are in the process of being published. The GitHub repository containing code associated with this project can be found here: https://github.com/garnerkohrell/Thesis_Appendix_Code.git
