Comment on “Towards improved USLE-based soil erosion modelling in India : a review of prevalent pitfalls and implementation of exemplar methods” by Majhi et al. (2021), Earth-Science Reviews 221, 103786

We found the study of Majhi et al. (2021) very interesting. The authors did an excellent job of evaluating the 100 USLE-based soil erosion studies undertaken in India and outlining the problems and errors encountered while estimating the USLE erosion factors in these studies. According to the authors, practically every study of the 100 research examined either overestimated or underestimated at least one of the five factors. We appreciate the excellent work of Majhi et al. (2021). Their research demonstrating the flaws in previous studies that employed USLE-based models to estimate soil erosion is precisely the type of work we need. However, we fear that Majhi et al. (2021) also made an error while evaluating the rainfall and runoff factor (R) equations that were based on the Modified Fournier Index. We highlighted the details in this discussion.
