Protection of the city of Novi Sad from floods relies mainly on levees along the banks of the Danube River. These levees were reconstructed after a great flood in 1965, when they were designed to protect the city from a 100-year flood level. This design flood level was the result of frequency analysis of annual maximum water stages for a 21-year long record (1947-1967). Such a choice of the observed record for frequency analysis resulted in levee heights that secured additional protection of Novi Sad from floods in last 40 years. Any other choice of record length and period would have resulted in lower design levels and poorer protection from floods. The paper discusses the effects of the choice of the subrecord on design flood level by investigating results of flood frequency analysis for different periods of observed water stages of the Danube at Novi Sad. The results show that the level of flood protection of the city of Novi Sad is now lower then designed 40 years ago.
