中文摘要 | 本研究為探討適合臺灣雨量資料之機率分布,藉以訂定頻率估計標準,以供有關單位決策實施之參考,並藉此使實際之工程設計規劃問題可尋求此規範解決,避免眾說紛歧之現象發生。研究中以合成資料探討有關頻率分析之問題,並為分析實測資料之依據。研究結果顯示,當著眼於全省、中區及南區時宜採用LN3分布、海生(Hazen)點繪法及修正資料之偏態係數。另當著眼於北區及東區時,宜採用PTⅢ分布、海生(Hazen)點繪法及修正資料之偏態係數。 |
英文摘要 | The objective of this research reported herein was to investigate the most appropriate probability distribution for the rainfall data in Taiwan. Hopefully, the guidelines for hydrologic frequency analysis could then be setup. In the present study, the synthetic data were generated and used to investigate the relevant problems in frequency analysis. Meanwhile, the results obtained from the study of synthetic data were directly employed for the analysis of the real data. The results indicated that the 3-parameter lognormal distribution with modification of the estimated skewness coefficient and the Hazen plotting position should be used when the analyzed rainfall data chose from the central and southern Taiwan area. Furthermore, the Pearson type Ⅲ distribution with the modification of the estimated skewness coefficient and the Hazen plotting position should be used when the analyzed rainfall data comes from the northern and eastern Taiwan area. |
