摘要

简要介绍了一种新的结合物理过程的尺度模型，并分析比较了应用尺度模型和传统频率分析方法（即直接计算法）来计算设计降雨的优劣势。使用香港新界北雨量站数据，发现尺度模型在降雨历时120

360

720和1 440 min范围内比较合理，计算得出的设计降雨比直接计算法得出的要小，且随着重现期的增加，两者的差异也相应地增加。结合了物理特性的尺度模型相较直接计算法更加合理，可以作为传统频率分析方法的一种替代或补充方案来计算设计降雨值。

Abstract

Incorporating physical characteristics of processes in hydrological analysis is one of the focuses of hydrological field. A scale model is introduced and its merits and limitations in calculating design rainfall depths

compared to traditional frequency analysis (direct method)

are analyzed in this paper. The data were collected from rainfall gauges of Hong Kong New Territory. It is found that the scale model is applicable for rainfall durations of 120

360

720 and 1 440 min. The calculated rainfall depths are smaller than those from the direct method. The differences between rainfall depths increase with return periods. It is concluded that the scale model is more reasonable than traditional frequency analysis and can be used as an alternative or complement to design rainfall depth calculation.
