Climate variability and change effects each parameter of hydrological cycle. Intensity, duration and frequency of precipitation is the basic information used in the design of bridges, culverts, city storm drainages. In this study, trend analysis of standart duration maximum precipitation was performed for 7 meteorological station equipped with pluviograph and located in İstanbul and around. Data series were divided two equal periods and precipitaion intensity-duration and frequency curves were developed. Except for Kartal MGI, significant increase trend were detected in 6 stations (Sarıyer, Kumköy, Florya, Çorlu, Göztepe ve Şile). As an example, relative difference between first and second half is 30% 5 hour standart duration and 2 years frequecy maximum precipitation for Sarıyer MGI and Q500 design flood discarge increased 60% Bekar Creek in Sarıyer.
