| 摘 要： | 以沿渡河流域为例,提出了同时考虑地形和降雨特性的汇流速度计算方法,引入半经验公式确定TOPMODEL模型中的地表径流演进速度,基于曼宁公式和连续性方程构建了降雨强度、地表坡度和汇流面积与地表径流演进速度的多元相关关系,并与采用单一平均汇流速度的TOPMODEL模型计算结果做了对比.结果表明,该方法模拟效果更好.

| Abstract: | Taking the Yanduhe Basin for an example,this paper proposes a new method to calculate concentration routing velocity by considering the topographic characteristics and rainfall properties.The surface routing velocity in TOPMODEL model is determined by semi-empirical formula,which the Manning formula and continuity equation are used to establish multivariant relationship between rainfall intensity,the slope of surface,concentration area and surface runoff routing velocity.The results are compared with those ... |
