Comments on “Comparison of Mann–Kendall and innovative trend method for water quality parameters of the Kizilirmak River, Turkey (Kisi and Ay, 2014)” and “An innovative method for trend analysis of monthly pan evaporations (Kisi, 2015)”

Abstract

Şen (2012) proposed the innovative trend analysis methodology and gave its fundamentals in a simple way based on logical deductions. Later, this methodology has been applied by many writers to different data as mentioned by Kisi and Ay (2014) and Kisi (2015), who also implemented the same methodology. In one of illustrations in their paper (Kisi and Ay, 2014) there are incorrectly scattered data and this comment includes the correction for the illustration. Additionally, Kisi’s (2015) application of innovative trend method, as explained in detail by Şen (2012, 2014, 2015), has invalid confidence limits (bands) and the invalidation is explained in the comment.
