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.

我们发现了 Majhi 等人的研究。（2021）非常有趣。作者出色地评估了在印度进行的 100 项基于 USLE 的土壤侵蚀研究，并概述了在估计这些研究中的 USLE 侵蚀因素时遇到的问题和错误。根据作者的说法，几乎所有 100 项研究的研究都检查了高估或低估了五个因素中的至少一个。我们感谢 Majhi 等人的出色工作。（2021 年）。他们的研究证明了之前使用基于 USLE 的模型来估计土壤侵蚀的研究中的缺陷正是我们需要的工作类型。但是，我们担心 Majhi 等人。(2021) 在评估基于修正傅立叶指数的降雨和径流因子 (R) 方程时也犯了错误。我们强调了本次讨论中的细节。
