流域出口 meaning in Chinese
basin outlet
watershed outlet
Examples
- Surface runoff was measured by an automatic gauge and a thin triangle weir vertically installed at the outlet of the watershed
在小流域出口处设置90薄壁三角堰和水位计记录了地表径流过程，分析了优先流和渗流、地表径流之间的关系。 - It can forecast flood real - timely and a course of any prospective flood . simulation model of runoff regards a drainage area as a system , simulating how one rainfall comes into being runoff in a basin . the import of system is rainfall , and the export is runoff
本文洪水预报采用产汇流模拟模型可以模拟任一时刻任一断面的径流量，对洪水进行实时预报，系统的输入是降水量，输出为流域出口的流量过程。 - 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。 - The results indicate that : only with a few rain gauges to adjust the radar estimated rainfall , authors could simulate the runoff as good as that from rain - gauge - network - measured rainfall ; the accuracy of radar rainfall estimation to heavy rain acts as a more important role than that of light rain ; the estimation error of amount precipitation over a period can be treated as an index for runoff simulation ability
在1500小时时间序列的比较试验表明，雷达估测面雨量和雨量计测量的面雨量都能较好地模拟每小时流域出口蒋集的出流量，数值试验还表明，雷达估测面雨量在某一时段上的均值误差作为一个指标可以较好地反映其应用于降水径流模拟时的精度总雨量和强降水的估测精度是雷达估测面雨量能否用于径流模拟的关键。 - The optimum interpolation method is used to estimate radar measured rainfall which then be applied to topmodel to simulate discharge of shiguanhe catchment during the summer of 1998 in game hubex project . comparison of simulated discharges between radar and rain gauge implements over a 1500 - hour series
运用雷达联合少量雨量计方法估测流域面雨量，结合game hubex国际合作项目1998年加强观测期在史灌河流域获取的水文观测资料和topmodel进行降水径流模拟，并与稠密雨量计站网测量的面雨量进行流域出口流量模拟的对比试验。
