  • 例句與用法
  • Study of estimating instantaneous unit hydrograph applying genetic algorithm
    遺傳算法在估計(jì)瞬時(shí)單位線參數(shù)中的應(yīng)用
  • Forest ecosystem ; hydrological system ; global change ; guandaushi watershed ; instantaneous unit hydrograph
    森林生態(tài)系、水文系統(tǒng)、全球變遷、關(guān)刀溪集水區(qū)、瞬時(shí)單位歷線
  • 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
    本文系以瞬時(shí)單位歷線為基礎(chǔ),進(jìn)行逕流歷線之模擬,同時(shí)將分析整理前兩年之觀測資料,所得之初步結(jié)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
    在臨前基流量較大或降雨強(qiáng)度較大時(shí),應(yīng)用瞬時(shí)單位歷線理論分析逕流特性之準(zhǔn)確性較高,然確實(shí)之適用條件仍有待進(jìn)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
    地貌單位線被看作是流域上各水質(zhì)點(diǎn)在弱相互作用下,到達(dá)流域出口匯流時(shí)間的頻率分布。對于一個(gè)典型的山坡型網(wǎng)格單元,匯流路徑由兩部分組成,即坡地部分和河道部分,為了得到匯流時(shí)間,必須首先確定匯流速度。坡地和河道的匯流速度隨著區(qū)域位置而變,并且必然與坡度有關(guān),因此,可首先計(jì)算流速的空間分布,進(jìn)而得到匯流時(shí)間的空間分布。
  • 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
    分析公伯峽流域所處地理位置及該流域內(nèi)的氣象特征,確定產(chǎn)、匯流模型采用超滲產(chǎn)流和瞬時(shí)單位線,河道匯流采用馬斯京根法,實(shí)時(shí)校正法由卡爾曼濾波和最小二乘法組成。
