Penentuan Jenis Distribusi Dan Uji Kesesuaian Smirnov Kolmogorov Data Hujan Das Taratak Timbulun Kabupaten Pesisir Selatan

Abstract: Rain significantly represent input component in hydrologi proses. Mostly, rain characteristic are intensity, duration and depth. Data of rain available to calculate floods discharge. Floods discharge data are needed to calculate water construction dimension in planning. Plan of rains is calculated by applying frequency distribution analysis such normally distribution, log normally distribution, gumbel distribution, frechet distribution, pearson III distribution, log pearson III distribution and others. Unequal results occur from each distribution analysis. Therefore, this research is supposed to determine suitable distribution to calculate plan of rains. Distribution type researchs conduct by calculating statistic parameter (Mean x , Standard Deviation S, Coeffisient of Variation Cv, Coeffisient of Skewness Cs, Coeffisient of Kurtosis Ck). It results suitable distribution for Log Pearson III in Catchment Area Taratak Timbulun. According to Smirnov Kolmogorov suitability test and drawing at probability sheets result Log Normal and Log Pearson III in Catchment Area Taratak Timbulun.
Key word: frequency distribution, probability, Smirnov Kolmogorov
