同時，為研究城市下墊面的產匯流特性研製了一套人工模擬降雨系統，並對相關評價指標進行了實測校驗。在此基礎上，進行了200多場降雨實驗，分析了雨強、歷時、土壤前期含水量、溫度、降雨量、不同下墊面和不同覆蓋度等對產匯流的影響，及各種因素對徑流系數的影響和相關性，建立了一定條件下歷時徑流系數，雨強徑流系數，流量徑流系數的函數模型。 -
The paper analyzes and summarizes the following laws of distinctive sediment yield produced in storm floods of the region based on predecessors ' study : storm is the main dynamic force of erosive sediment yield and storm, flood and sediment exist an inevitable relation ; the flood occurring time is concentrated with high peaks and huge volume, suddenly rising and suddenly falling and has decisive influence to the formation of a major flood peak in the middle yellow river ; the main reasons of concentrated coarse sediment of the river is severe erosive sediment yield, strong sediment transporting capacity and high sediment concentration ; the important influence of frequent or continued storm floods happened in he - long reach especially in coarse sediment concentrated region to the sediment transport of the yellow river and ; along with the increase of harnessing, regional flood trend is becoming smaller but the variation of sediment quantity is not obvious and the reaction of peak discharge and flood runoff of majority tributaries are not sensitive, showing that a general and normal engineering works can not effectively control regional major floods especially the sediment of an extraordinary flood
摘要在前人研究的基礎上分析總結了該區特有的暴雨洪水產沙規律：暴雨是侵蝕產沙的主要動力，暴雨、洪水、泥沙之間存在著必然的關系；洪水發生時間集中，峰高量大，暴漲暴落，對黃河中游大洪峰的形成具有決定性影響；侵蝕產沙強烈而粗泥沙集中，輸沙能力強，洪水含沙量高，是黃河粗泥沙的集中來源地；河龍區間特別是粗泥沙集中來源區頻繁或連續的暴雨洪水對黃河輸沙有重要影響；隨著治理水平的提高，區域洪水有減小趨勢，但泥沙量變化不明顯，大部分支流的洪峰流量、洪水含水量反應不敏感，說明一般規模和水平的治理工程還不能有效控制區域大洪水特別是特大洪水的泥沙。 -
In low developed non - karat mountain area, the main water supply patten is fetching water from a river, water - fetching building is built mostly on the bank or at the bottom of the river, it seemed to be fetching water from underground, but the quantity of the water depends on the runoff of the river, so it has close relationship with surfacewater actually
摘要人類利用開發程度較低的非巖溶山區一般以近河取水為主要供水方式，取水建築物多位於河岸或河底，從供水形式上看屬于取用地下水，但取水量的大小依賴于河流流量，因此實質上和地表水關系更加密切。 -
According to the three rives ( liaojaogang, fanshen, yanggang ) in haian county, this paper concluded the quantity of field water pollution source by on the point water monitoring, through respective analysis of direct runoff in urban and countryside
摘要以海安縣城鎮「三河」 （洋港河、翻身河、老焦港河）流域為例，分別對城市地表徑流、農村地表徑流進行了分析、測算，並通過對水質現場監測，給出了「二河」流域內的面源污染量。 -
Therefore, the optimization of the forward electric quantity of entan hydropower station is mainly studied with the model of optimizing annual forward electric quantity constucted based on the forecasting inflow runoff to reservoir, the model is solved by using niche genetic algorithm and the results can be taken as the basis for the owner to sign the forward market contract
因此本文重點研究了二灘水電站的年期貨電量的優化問題，建立了年期貨電量優化模型，以基於徑流趨勢預測方法選用的入庫徑流量為依據，用小生境遺傳演算法對模型進行求解，計算結果可作為該公司簽訂期貨合同的依據。 -
When precipitation rainfall is of the same quantity, the area there is steep grade is easier to give birth to runoff than where is flat grade
當降雨量相同時，坡度大的地區較坡度小的地區容易產生徑流。 -
Through the statistics and analysis of runoff and amount of sand lost in the downstream of weihe in recent years, it is discovered that in the downstream of weihe the magnitude sand season was ahead of the main flood season relatively within the year ; variation tendency of annual runoff and amount of sand lost was identical basically, and the quantity of water and sand at huaxian gauging station was tailing - off continuously from the 1960 to 2005 ; there was direct relation between the situation of rushing or silting deposits and rainfall at this section of the river : the river depositing in the year which is rich rainfall, the eroding in the poor rainfall
摘要本文通過對近6年渭河下游水沙量數據的統計和分析得出，渭河下遊河段年內多沙期較河流主汛期有所提前；年徑流量和年輸沙量的變化趨勢基本一致，而且自60年代至2005年華縣站的水沙量持續呈遞減趨勢；河流的沖淤情況與該河段的降雨量有著直接的關系，當年平均降雨量小的時候河流以淤積為主，當年平均降雨量大的時候河流以沖蝕為主。 -
It could be seen that the influence of human activity on stream runoff is very obvious. the quantity of downstream flow depends on precipitation over a catchment and withdrawal from the upstream
