小范围强降雨或超强降雨引起的突发性、量大、持续时间短的局部洪涝灾害增多，对自然环境、人类生命、公众健康和财产等构成最大的潜在威胁。这类山洪具有径流和泥石流迅速上升的特点，几乎没有预警，以防洪灾破坏。通过对小流域长期观测雨量资料的降雨-径流模型所生成的过程线特征进行量化，通过求取相同尺度相对严重度因子的平均值，建立了洪水指数，并给出了降雨特征与洪水指数之间的回归方程。研究目的是将降雨强度-历时-频率关系与概率降雨资料中的洪水指数相结合，建立洪水指数-历时-频率关系曲线，以评估设计暴雨对极端洪水的易损性。这项研究是对现有和计划中的防洪设施设计暴雨的山洪严重程度进行量化的初步努力，以应对近年来频繁发生的极端山洪造成的残余洪水风险。
There has been an increase in the occurrence of sudden local flooding of great volume and short duration caused by heavy or excessive rainfall intensity over a small area, which presents the greatest potential danger threat to the natural environment, human life, public health and property, etc. Such flash floods have rapid runoff and debris flow that rises quickly with little or no advance warning to prevent flood damage. This study develops a flash flood index through the average of the same scale relative severity factors quantifying characteristics of hydrographs generated from a rainfall-runoff model for the long-term observed rainfall data in a small ungauged study basin, and presents regression equations between rainfall characteristics and the flash flood index. The aim of this study is to develop flash flood index-duration-frequency relation curves by combining the rainfall intensity-duration-frequency relation and the flash flood index from probability rainfall data in order to evaluate vulnerability to extreme flash floods in design storms. This study is an initial effort to quantify the flash flood severity of design storms for both existing and planned flood control facilities to cope with residual flood risks due to extreme flash floods that have ocurred frequently in recent years.
