ANALYSES OF INTENSITY PRECIPITATION FOR THE DIMENSIONING OF DRAINAGE FACILITY OF RAINFALL ON THE AREA TOWN DARUVAR

Za potrebe dimenzioniranja objekata odvodnje oborinskih voda područja grada Daruvara provedena je vremensko-prostorna analiza oborinskih osobina, koristeći povijesne podatke mjerenja kratkotrajnih oborina s meteorološke stanice Daruvar. Na primjeru meteorološke stanice Daruvar prikazani su osnovni klimatski podaci i hidrološke osobine prostora na kojemu se vrši dimenzioniranje objekata odvodnje, kao i načini te metode mjerenja oborina na meteorološkoj stanici. Obavljena je analiza oborina sa meteorološke stanice Daruvar iz povijesnog razdoblja mjerenja (1991-2010), te izvršen proračun vjerojatnosti maksimalnih intenziteta kiše trajanja od 10 min do 60 min. Proračuni vjerojatnosti pojave maksimalnih količina oborine obavljeni su statističkom analizom sastavljenog uzorka primjenom empirijskih i teoretskih funkcija raspodjele vjerojatnosti.For the purposes of dimensionings drainage facilities of the rainfall of area the town Daruvar has been carried out time-space analyses of rainfall characteristics, using historical data of measurements of short-term rainfalls with the weather station Daruvar. On the example of weather station Daruvar has been presented basic climatic data and hydrological characteristics of space on which perform dimension drainage facilities, as well as approach measurement method of rainfall on the weather station. Has been performed analyses of rainfalls with the weather station Daruvar from the historical measurement period (1991-2010), also performed the calculation of probabilities of the maximum intensities rain duration from 10 minute to 60 minute. Calculations of probability maximum rainfall have been performed by the statistical analysis of constituted sample by using of empiria and theoretical function of probability distribution
