ORUSpy A Python version of the ORUSCAL (Orchard RUSle CALibration) model to automate soil erosion risk assessment at field level using the RUSLE methodology

This document describes how to use ORUSpy. This model was developed based on ORUSCAL (Gómez et al., 2020), an Excel tool that was built to evaluate soil erosion risk at field level. Details are provided about how to download the model, set up the input data required for the simulation and how to interpret the outputs. More detailed information on calculation procedures and model parametrisation can be found in the "Science Documentation" and the "User's Reference Guide" for the Official NRCS RUSLE2 Program developed by the USDA and the associated citations that can be found in the reference list at the end of the document.
