Choi, K; Huwe, B; Reineking, B: Commentary on "Modified MMF (Morgan--Morgan--Finney) model for evaluating effects of crops and vegetation cover on soil erosion" by Morgan and Duzant (2008), Geophysics (physics.geo-ph), http://arxiv.org/abs/1612.08899 (2017)
Abstract:
The Morgan-Morgan-Finney (MMF) model is a widely used semi-physically based soil erosion model which has been tested and validated in various land use types and climatic regions. The latest version of the model, the modified MMF model, improved its conceptual physical representations through several modifications of the original model. However, the modified MMF model has three problematic parts to be corrected: 1) the effective rainfall equation, 2) the interflow equation, and 3) the improperly normalized C-factor of the transport capacity equation. In this commentary, we identify and correct the problematic parts of the modified MMF model, which should result in more accurate estimations of runoff and soil erosion rates.
