查询词典 runoff

And it has given the effects of the all factors on the runoff by 1D river networks mathematical model. Due to the natural and artificial influences, the water-sediment transport has greatly changed. It is characterized by marked decrease in runoff and sediment diverted from these outfalls and increase in water-sediment transport of main stream. The key factors causing these changes are aggradation of the three outfalls channels and Jingjiang river cutoff work.

同时研究还发现，雅鲁藏布江干支流在20世纪60年代左右径流量较大，但在进入60年代中后期之后，年径流量呈逐渐减小的趋势，这种趋势在80年代附近达到极小值，此后径流量逐渐回升，并在90年代后逐渐进入相对丰水期。

It was found that, for the control treatment the average runoff depth was 3.72mm per 10mm, the water loss index was 37.2%, the average soil erosion was 43.6 kg*hm-2*10mm-1, and the soil erosion modulus was 7.42 t*km-2*a-1, which are all high in the 4 treatments. For the other three treatments, the surface runoff and the average soil erosion amount were 2.20%-67.08%and 43.81%-90.83%lower than those of the control, respectively. The most effective pattern for soil conservation was the artificial forest with underbrush treatment, and the best water conservation pattern was the treatment of planting tea bush on contour terrace.

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 result showed that hole shape and banding shape of soil preparation could significantly decrease runoff and soil erasion amount,and hole shape of soli preparation was the best to decrease runoff and soil rasion amount by 34% and 42% respectively.

结果表明，穴状整地林和带状整地林对减少地表径流和土壤侵蚀均具有明显的作用，对减少营养元素的流失量作用显著，年减少土壤养分流失量为79.75～135.40kg·hm－2·a－1。

Based on the mentioned above ideas, it describes a method to determine the parameters involved in the hydrologic models when considering the effect of human activity on runoff. By the approach, the runoff is more clearly revealed. The concept of pattern unit hydrograph and its estimation method are presented.

基于上述思想，阐述了考虑人类活动影响的流域水文模型参数的确定方法，将人类活动影响纳入流域水文模型参数的确定过程中去，可以更深刻地了解流域水文的基本规律，揭示人类活动对其径流的影响。

Firstly, this paper studies the trend of the natural runoff of Huayuankou station, and then studies changing characteristic of runoff of Huayuankou station under the human activities. These human activities include runoff retention and use, growing industrial, agricultural and domestic water demands, water conservancy project and interlatitudinal water transfer project.

首先以花园口站为例，分析其天然径流的变化趋势，然后从黄河流域径流拦蓄及利用、工农业及城乡用水量的增加、水利水保工程措施运用及流域调引水等因素中，分析近年来人类活动的加强对花园口站径流规律特性的影响及变化规律。

Statistical analysis shows that bulk density, saturated hydraulic conductivity, and dust on road surface have significant effects on runoff and soil loss. Stone cover may increase surface runoff, but vegetation cover is very effective in erosion control and runoff reduction.

土质道路的容重和路面浮土与径流系数和土壤流失量呈显著正相关，饱和导水率则呈显著负相关；路面杂草能显著减少径流，防治路面侵蚀。

By theory analyzing and example calculation and comparison, the conclusion is obtained that the traditional inferential method can be applied in the design flood peak flow calculation, yet it cannot truly express the runoff process of the rain drainage inlet, the instantaneous unit hydrograph depending on the real and actual datum is different to be used in the runoff discharge hydrograph calculation, and the no linearity reservoir means and the isochronal method have some physics base and its parameters easily evaluated and its runoff discharge hydrograph still more is close to practice.

5通过城市雨水地表汇流特性及计算方法的理论分析、实例计算和对比得出：传统推理法可应用于城市设计洪峰流量的计算，但不能真实地反映雨水口径流流量过程；瞬时单位线法等对实测资料有较大依赖，难以应用于城市径流流量过程线的计算；非线性水库法和等流时线法的径流流量过程线接近实际。

Compared with the exponent function, the power function can be more suitable for fitting the change of chemicals concentrations in runoff under unsaturated conditions from the loess slope,as well as,the mass loss of potassium and bromine in runoff,but not for initial phase. The study offered a reference for developing the model of soil nutrient in runoff transport of the loess slope.

同时利用两种类型描述径流养分浓度模型对实测资料进行分析，结果显示与指数函数模型相比较，采用幂函数模型能够较好地模拟黄土坡面非饱和条件下径流溶质浓度变化过程，同时幂函数模型也能够较好地描述径流中钾离子和溴离子的质量变化过程，为进一步完善黄土坡面径流养分迁移模拟模型提供了参考。
