    遗传算法在估计瞬时单位线参数中的应用
  • Study on the real time checking model of procedure forecasting of unit line method
    单位线法汇流过程预报的实时校正模型探讨
  • Application of the c . o . clark unit hydrography to the flux computation in a small scale basin of the loess plateau
    单位线在黄土高原小流域汇水演算中的应用
  • The results show that the minus value and fluctuation of unit hydrograph can be mitigated and the error of observed discharge can be withstood using the robustified ridge estimation
    最后采用抗差岭估计来推算单位线,该方法既可以解决共线性的问题,也可以抗御粗差的影响,得到比较稳定的单位线。
  • All the methods can calculate the flood based on the storm data . the software can be used in henan province . additionally , the rational formula method and the plain drainage method can be used in other regions near henan province , even farther regions
    软件包括推理公式法、单位线法、平原排涝公式法三种由暴雨资料推求设计洪水的计算方法,除了适用于河南省中小流域设计洪水外,推理公式算法、平原区排涝公式算法也可在邻近省市和更大的范围内推广使用。
  • 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
  • The geomorphological instantaneous unit hydrograph ( giuh ) is viewed as the frequency distribution of the times of arrival of individual water deoplets at the catchment outlet . the travel path , for a typical hillslope cell . consists of a hillslope fraction , corresponding to overland flow and a stream fraction , corresponding to concentrated channeled flow . to obtain the time of travel , velocities must be defined . hillslope and stream velocities vary with location and must be strongly correlated with slope , and therefore a spatial distribution of velocities and hence of travel times could be obtained . the present methods of giuh neglect any time delays associated with overland flow pathways
    地貌单位线被看作是流域上各水质点在弱相互作用下,到达流域出口汇流时间的频率分布。对于一个典型的山坡型网格单元,汇流路径由两部分组成,即坡地部分和河道部分,为了得到汇流时间,必须首先确定汇流速度。坡地和河道的汇流速度随着区域位置而变,并且必然与坡度有关,因此,可首先计算流速的空间分布,进而得到汇流时间的空间分布。
  • 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。
