It is well-known that precipitation events may intensify due to climate
change, potentially affecting maximum precipitation values, essential for
hydrological design and water resources management applications. For this
reason, it is important to determine the changes in the maximum precipitation
series. Trend analyses were conducted using the Mann-Kendall (MK), innovative
trend analysis (ITA), and improved visualization of innovative trend analysis
(IV-ITA) methods to detect changes in maximum precipitation series from five
meteorological observation stations operated in Kastamonu Province, northern
Turkey, namely: İnebolu, Bozkurt, Devrekani, Kastamonu, and Tosya, being
vulnerable to floods. The data cover a period from 1989 to 2020, including 14
standard durations from 5 min to 24 hrs. Considering the MK test results, no
significant trend mainly was found. On the other hand, according to innovative
methods, increasing/decreasing trends were revealed, with a majority of
increases. The station operated in Bozkurt district, which has been very sensitive
to floods, showed increasing trends in short durations of precipitation and
decreasing trends in medium and long durations of precipitation.
