查询词典 runoff primary

The results showed that covering the dich slopes with shrub could significantly increase soil shear strength, compactness and moisture content, and the formed vegetation had significant effects on retarding runoff and removing TSS (P.05). Applying live fascines could significantly increase soil shear strength and TSS removal rate (P.05), but its effects on increasing soil compactness and moisture content and retaining runoff were not significant.

The research quantified the effects of geographical environment factors about runoff and sediment generation to provide rationable foundation to differentiate cell of runoff and sediment generation and to the construction of ecological environment in a watershed.

定量评价影响渭河流域产水、产沙的地理环境要素因子，为渭河流域产水、产沙格局划分及流域生态环境建设提供理论依据。

During the establishment of sediment yield dynamic model at the watershed outlet, it was difficult for us to carry out dynamic monitoring of each impact factors in the whole basin, because it was a long time research and was in very large-scale watershed. Taking into account the interannual variability of sediment yield mainly affected by hydrological conditions of rainfall - runoff and underlaying surface changes caused by soil conservation measures, a combined influence factor which is related to surface runoff modulus and the implementation time of the water and soil conservation project was proposed for the first time. Furthermore, its specific expression was determined through dimensional analysis and non-linear regression multianalysis.

在流域输沙量动态模型的建立中，由于研究时段长、研究流域尺度大，对输沙量各影响因子进行全流域逐年动态监测十分困难，考虑输沙量的年际变化主要受降雨-径流水文条件和水土保持措施等土地管理活动的影响，首次提出与地表径流模数和治理时间相关的综合影响因子，并通过因次分析法和二元非线型回归法确定了具体的表达式。

Wavy distribution of soil water along hillslope resulted from the fluctuation of runoff, upslope runoff infiltration, lateral downslope flow, and the difference of infiltration rate and evapotranspiration.

4土壤水分沿坡面呈&波浪形&分布是坡面径流的波动性、上方来水的沿程入渗、侧向沿坡向下流以及坡面各处入渗性能和蒸发蒸腾作用的差异等综合作用的结果。

The pollution caused by the washoff of urban stormwater runoff from surface is the critical part of the non-point pollution. With deepened the control of the point pollution, it is serious day by day that the receiving water is polluted by urban stormwater runoff.

城市雨水径流冲刷地面而引起的污染是面源污染的重要部分，随着点源污染治理的深入，城市雨水径流对受纳水体的污染己日益凸现。

As this method calibrates all the model parameters in one procedure, and there is no need to separate the runoff, it can reduce the error caused by model parameter calibration due to intentionally separate runoff.

由于该方法同时优选所有模型参数，不需要对实测径流进行分割，从而可避免人工分割径流而出现的参数率定误差。

The experimental results show that there is no runoff on test slops of any declivities with rainfall less than 9mm, and the runoff efficiency and rainfall are in direct proportion with rainfall larger than 9mm, which is more obvious on slope than on flat land.

试验结果表明，降雨量小于9mm时试验坡度的草坪绿地均不产流；次降雨量大于9mm时，绿地的径流效率与次降雨量成正比，而坡地上二者的相关性比平地更加显著。

Modeling and test are carried out in a group of series tanks separately in seven sub-valleys. After emending the parameters to every single tank using the hybrid genetic algorithm, the general runoff by way of adding all the runoff in every tank in the sub-valley has been acquired.
