General Comments:This Letter to the Editor is included in the database because the original article that the author is commenting on is already included in the database. The author states that 335 searched documents (11% of 3057 documents) were unrelated to “non-point source pollution” due to the search methods used in Web of Science in the original study. He cites several example studies that were wrongly included in the original overall analysis including two SWAT review articles that are both included in the literature database; i.e., Gassman et al. (2007) and Arnold et al. (2012). However, it is not clear exactly what the author's argument is, at least regarding the two SWAT studies, because the Gassman et al. (2007) and Arnold et al. (2012) studies both provide extensive review of SWAT nonpoint source pollution applications and/or issues.
