  • prompt subsurface flow

例句与用法

  • Effect of pipe flow on interflow on granite slope in three gorges area of yangtze river
    长江三峡花岗岩坡面管流在壤中流中的作用
  • On the development process , the rills were influenced by rainfall runoff on slope , but the sockets were the result of the long - term repetitious action of rainfall and runoff and subsurface flow
    在发展过程上,前者受降雨径流侵蚀作用时间集中;后者是在长期多次降雨形成地面径流和壤中流侵蚀的共同作用下,逐渐发展起来。
  • On the formation mechanism , the rills were mainly formed by the concentrated action of the runoff on dyke slope , while the formation of socket mainly depended on surface runoff , subsurface flow and the existing defects within the dykes such as crack , mouse hole , fox and brocks dens
    在成因上,前者主要是降雨形成超渗地面径流的集中对戗坡的侵蚀作用而形成;后者主要与坡面径流、壤中流,以及土堤的薄弱点(如裂缝、鼠洞、狐1一灌洞等)有关。
  • When soil antecedent condition is dry and the initial rainfall intensity is high , peak surface runoff also considerably lag behind that of rainfall , because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response , only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism , and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h , indicating the existing of macropores and pipe flow in cultivated layer
    2 )耕作制下紫色土的产流主要机制是: 1 )当雨前土壤含水量未达到饱和状态时,表面产流起始时间有明显滞后现象,这与紫色土的快吸水性和较多非毛管孔隙密切相关;当雨前土壤较干燥,降雨初期雨强较大时,易形成临时相对不透水表层,表面产流峰也有明显滞后现象。 2 )表面径流的产流方式主要是超渗产流,当土壤达到饱和状态后,有四川大学博士学位论文小部分回归流发生,但主要是饱和超渗产流发生,因为紫色土的相对不透水层和其它透水障碍层不明显。 3 )壤中流主要是饱和产流,与降雨过程有明显的滞后,而且雨停后的壤中流产流历时与降雨特征无关。
  • For the soil infiltration , generally , the order of the original and stable infiltration speed from big to small is the inner , the outer space and the paludal trace , as well as layer a b . in the view of the rainfall balance of the wildwood , the canopy interception is averagely 61 . 10 % of the rainfall , the trunk runoff 0 . 80 % , the inner 38 . 10 % , the surface and the litter evapotranspiration 18 . 00 % , the surface runoff does n ' t appear in the forest , and the interflow is also very small , which is 0 . 30 % of the total rainfall ; the conflux is 21 . 10 %
    原始森林的水量平衡中,林冠截留量平均占降雨的58 . 27 ,树干径流量占降雨的0 . 80 ,林内降雨占降雨的40 . 93 ,地表蒸发及地被物蒸散量占总降雨的20 . 13 ,林内很少发生地表径流,壤中流量也极少,只占总降雨的0 . 07 ;汇流量占总降雨的21 . 43 。
