Water resources planning requires very good data set and accurate analyses, one of which is a trend identification procedure. Different trend analyses are available in the literature and one of the most commonly used one is the Mann-Kendall trend analysis. The biggest problem of this analysis is that trends change with the selection of different time periods. Although many researchers have tried to find different solutions to this problem, in this study, trends are set for all combinations of the available data to cover at least 10-year periods and the results are displayed on a 3-dimensional checkerboard. For the application precipitation and temperature data are considered from 5 meteorology stations in the Akarcay, Turkey.
