| 摘 要： | 以重庆市开县温泉流域(984km2)为研究区域,利用自动雨量站资料作为TOPMODEL(TOPography based hydrological MODEL)降水一径流模型的输入,以08:00 BST观测的流域出口流量作为模型率定的依据,探讨了用小时面雨量和08:00流量资料和TOPMODEL水文模型进行小流域流量模拟的可行性.结果表明,以08:00流量为依据对TOPMODEL水文模型进行率定后,模型效率系数达到0.872.结果表明,TOPMODEL在所研究的流域基本上是适用的.此工作是自动雨量站资料、天气雷达定量测量降水产品等用于小流域山洪预报的基础工作之一.

| Abstract: | The rainfall runoff model TOPMODEL (TOPography based hydrological MODEL) is use
d to simulate the hourly runoffs for Wenquan catchment (984km2) in Kaixian, Ch
ongqing Municipality. The performance of TOPMODEL in the study area is addressed
based on the rain gauge observations and 08:00 BST runoff data. It mani
fests that the TOPMODEL performed well in the study catchment, and the Nash and
Sucliffe efficiency criterion is 0.872 when calculated with 08:00 BST runoff dat
a. Since the method is simple and the data are easily obtained, th
is presentation is one of the foundational studies for the developments in the u
se of rain gauge observations and radar rainfall estimates for flash flood analy
sis and forecast. |
