| 摘 要： | 本文应用隐含马尔柯夫链的概念,阐明了地貌特征瞬时单位线的基本原理,推导了三、四、五级流域的数学模型.用南方和北方地区六个流域的93次实测洪水资料对模型进行了检验,结果表明,地貌IUH计算的洪峰流量的合格率达到80%以上.本文还建议了对无资料地区推求作为动力特征的特征流速的方法.

| Abstract: | Applying the concept of the imbedded Markov process, this paper describes the elements of Geomorphologic Instantaneous Unit Hydrogroph and gives the mathematical models for 3, 4 and 5-order basin. 93 flood events from 6 basins of Southern and Northern region are tested by comparing the observed runoff with the calculated one. The agreement between both seems remarkable, A proposed method about the estimation of characteristic velocity as a main parameter of IUH for the region which has no discharge record is also presented. |
