In DMMF: Daily Based Morgan-Morgan-Finney (DMMF) Soil Erosion Model

Example data from the convex potato field from Arnhold et al. (2013)

Description

Example input data for running the DMMF function. This data is based on the field data from the convex potato field described in Arnhold et al. (2013) with optimized parameters described in Choi et al. (2017).

Usage

data(Potato.Convex)
