變煥法에 의한 設計渴水量의 誘導 = Derivation of design low flows by transformation method

다국어 초록 (Multilingual Abstract)

Derivation of reasonable design low flows was attempted by comparative analysis of design low flows derived by Power and SMEMAX transformations for the normalization of skewed distribution in the four watershed of main river basins in Korea.
The results were analyzed and summarized as follows.
1. Basic statistics of annual low flows for the selected watersheds were calculated by using Power and SMEMAX transformations.
2. Power transformation has found to be the best for the normalization of skewed distribution among others including Log, Squareroot and SMEMAX transformations.
3. Design low flows for the seleted watershed were derived by the Power and SMEMAX transformations.
4. Judging by the relative suitablities for the Power and SMEMAX transformations, it was found that design low flows using two methods are closer to the observed data within 10 years of the return period, and those of Power transformation can be acknowledged as a reasonable one in comparison with SMEMAX transformation over 10 years of the return period.
