河道汇流 meaning in English
concentration of channel
Examples
- Through examination of the recession limbs of the observed hydrographs , during periods with no rain and thus no surface runoff , one can determine the value of . for this catchment , a value of 0 . 8 is obtained . the simulated subsurface runoff at each grid is routed to the outlets through a unit - hydrograph method for overland flow and the linear saint - venant equation for channel flow to get the discharge at xixian station
对所研究的流域而言,经过估算消退系数为0 . 8 .耦合着这两种不同地下径流机制的clm模型都可以计算出每个网格的地表地下径流深,采用dag lohman 34 , 35发展的汇流模型进行汇流由于是研究地下径流,所以取每个网格的地表径流为0 ,该模型采用单位线计算坡面汇流线性圣维南saint - venant equation进行河道汇流 - Based on studying of the unequal rainfall in space - time and the asymmetry physical geography parameters in space , which can influence the process of the runoff , this paper puts forward a sort of slope conflux and watercourse conflux simulating model based on grid , and that gains flux at random time and grid in basin
本模型针对降雨时空分布不均匀与下垫面自然地理参数空间分布不均匀，对产汇流形成过程的影响，提出了一种基于栅格的坡面产汇流与河道汇流的数值模拟模型。 - A new method is presented . the travel time , including the time delays associated with overland folw pathways , is obtained . it is expected that the hillslope velocity and the stream velocity are different , and different equation is used . in the method , the fact that velocity increases going downstream in river systems is taken into account . after the travel time of each cell being calculated , the frequency distribution of the times of arrival of individual water droplets at the catchment outlet - giuh , is obtained
提出了一种汇流时间计算方法，汇流时间中包括坡地漫流时间和河道汇流时间。方法中坡地单元的汇流速度与河道单元的汇流速度采用不同的计算公式，同时考虑流速沿河道向下游的变化。流域中每一个网格单元的汇流时间得到后，将其看作随机变量，进行统计分析后，得到汇流时间的频率分布? giuh 。 - Geography position and meteorology character in gongboxia watershed are analyzed , according to which the excess of infiltration and instantaneous unit hydrograph are used in runoff and affluence models , and muskingum routing method in river course affluence , kalman filtering technique and least square method in real - time correction
分析公伯峡流域所处地理位置及该流域内的气象特征，确定产、汇流模型采用超渗产流和瞬时单位线，河道汇流采用马斯京根法，实时校正法由卡尔曼滤波和最小二乘法组成。
