Log-Pearson Type III 및 GEV분포모형에 의한 강우의 지점 및 지역빈도 비교분석
Comparative Analysis of regional and at-site analysis for the design rainfall by Log-Pearson Type III and GEV Distribution
초록
This study was conducted to draw design rainfall for the regional design rainfall derived by the optimal distribution and method of frequency analysis. The design rainfalls were calculated by the regional and at-site analysis for Log-Pearson type III and GEV distributions and were compared with Relative efficiency(RE) which is ratio of Relative root-mean-square error(RRMSE) by the regional and at-site analysis for Log-Pearson type III and GEV distributions. Consequently, optimal design rainfalls following the regions and consecutive durations were derived by the regional frequency analysis for GEV distribution and design rainfall maps were drawn by GIS techniques.
