| 2. | Abstract : since the 20th century , a great progress has been made in research on infiltration and runoff yield
文摘: 20世纪以来，入渗与产流研究取得了长足进展。 |
| 3. | Based on the results obtained as stated , it is thus suggested that with improvement in data conditions , runoff yield could be calculated on grid format and results for both models appropriately enhanced
同时结果还表明，在资料条件允许下，产流可以基于单元格计算，这样两个模型的结果都会得到改善和提高。 |
| 4. | An omnibus model is used to calculate runoff yield . it consists of two runoff yield patterns . one is swb model , which means the runoff yields at the time when the rainfall intensity exceeds the infiltration intensity
本文采用垂向混合产流模型进行产流计算，采用简单水量平衡模型swb来计算超渗产流，然后按蓄满产流模型来计算蓄满产流。 |
| 5. | Some developments and results in influence factors of infiltration , computation and analysis of infiltration , hillslope runoff yield and watershed runoff yield in china and other countries are introducted , and some brief reviews on them are given
该文从入渗影响因素、入渗计算与分析、坡地产流、流域产流4个方面，着重介绍了国内外研究的若干成果和进展，并做了简要的评述。 |
| 6. | ( 2 ) the effects of rainfall on the runoff and sediment in the weihe river are studied . it is pointed out that the rainfall is much less than the average . especially during the flood season , which results in the lower runoff yield
( 2 )分析了降雨特点及对渭河流域水量的影响，指出90年代全流域降水量比多年平均值偏少，尤其汛期雨量偏少较多，因而同样降雨条件下，产流量偏少。 |
| 7. | Considering that the infiltration capacity curve can ' t express the actual infiltration capacity , the authors develop the surface runoff yield models that combine with the infiltration capacity curve , unstable raining process and antecedent soil moisture in each rainfall or over a duration time
考虑到流域实际的下渗能力，建立了将下渗能力曲线、不稳定降雨过程和前期土壤含水量有机联系起来的流域场（时段）暴雨地表径流计算模式。 |
| 8. | Abstract : in accordance with the problems in the system of well storing rainfall at present , based on the experiments of artificial simulating rainfall , and assistance with the measures of natural rainfall , the relationships among the surface runoff yield , silt concentration , catching runoff efficiency and the material of surface , slope gradient , rainfall intensity are analysed systematically . then , the best slope gradient and material of surface are chosen , in condition of which surface rainfall yield is the largest and silt concentration is the smallest . this is a beneficial study for the practical use of the rainwater catchment plot in furture
文摘:针对当前旱井集雨系统存在的问题，利用人工降雨试验，并辅以天然降雨观测，系统分析了旱井集流区的产流量、含沙率、集流效率与下垫面材料、坡度、降雨强度的关系，进而选出了最优坡度及最优下垫面材料，为今后旱井集流区的应用研究做了有益的探讨。 |
| 9. | ( 2 ) the results of the rainfall - affected runoff scouring experiments in lab . when the rainfall intensity was less than l . omm / min , the soil erosion caused by the combination of rainfall and the upslope runoff was more than that caused by only the simulated rainfall . when the rainfall intensity was more than 2 . 0mm / min , the upslope runoff strengthened the effect of the runoff yielded in the local area on the dyke slope surface , and the effect increased with an increase of rainfall intensity
2 、室内模拟降雨+放水冲刷试验结果雨强小(如i 1 . 0mm min )时，上游注入水量对戗坡侵蚀作用比降雨在戗坡上所产生径流的侵蚀大；雨强大时( i 2 . 0mm min ) ，上游水量下泄与当地降雨径流一起增强对戗坡面的侵蚀作用，雨强越大，侵蚀作用也越大。 |
