- Study of estimating instantaneous unit hydrograph applying genetic algorithm
遗传算法在估计瞬时单位线参数中的应用 - Forest ecosystem ; hydrological system ; global change ; guandaushi watershed ; instantaneous unit hydrograph
森林生态系、水文系统、全球变迁、关刀溪集水区、瞬时单位历线 - According to the collected data in first two years , the study tried to simulate the runoff model by the instantaneous unit hydrograph theory and analyzed the data , the results were shown as follows
本文系以瞬时单位历线为基础,进行迳流历线之模拟,同时将分析整理前两年之观测资料,所得之初步结果列述如下: - The instantaneous unit hydrograph theory would be suitable for the high antecedent baseflow and the high rainfall intensity to estimate the direct runoff , but it still needs to prove its fitness with much more cases
在临前基流量较大或降雨强度较大时,应用瞬时单位历线理论分析迳流特性之准确性较高,然确实之适用条件仍有待进一步之研究。 - 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。
