- Example Sentences:
| 1. | 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。 | | 2. | The reason is that the quality and function of current forest can not match the natural primeval forest with perfect soil conservation effectiveness . because unitary surface material and less land surface roughness which can not retain runoff lead to short confluence time , quick delivery of flood , easy superposition of floods , and result to flood disaster
原因是目前的森林质量和功能都无法与具有水土保持功能的原始森林相比，其地表组成物质太少且单一，地面粗糙度低，起不到对地表径流的阻挡作用，致使地面径流汇流时间缩短，洪水下泄快并容易形成洪水叠加，导致洪涝灾害加剧。 | | 3. | 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 。 |
