    根据我们对新乡地区内沿黄大堤的调查,每年暴雨径流侵蚀大堤的土方量约达7 104m3以上。
  • In order to eliminate the hidden trouble caused by storm runoff erosion , the mechanism of the storm runoff erosion on the slope surface of the yellow river dykes has been studied in this thesis . through the simulation rainfall experiments and field observations , the formation mechanism of storm runoff scouring , rills and sockets have been opened up . meanwhile the possible control measures have been suggested
    为了防治黄河大堤由于暴雨径流冲刷造成的不安全隐患,本文针对黄河大堤上的暴雨径流侵蚀进行了实地设站观测及室内模拟降雨侵蚀试验,通过揭示大堤暴雨冲刷过程机理,查清水沟、水穴(浪窝)等的成因,提出相应的防治对策。
  • In light of current using situation and drawing on the experience of many scholars researched methods and viewpoints , this thesis made com land , fallow land , orchard , grass land as experimental field in black soil region jlau , which carried out experiment by applying different amounts of n and p fertilization in corn field . by means of collecting the samples of rainfall runoff , erosion silt and surface layer soil before and after rainfall for one year nature precipitation in field , we study the effect of surface runoff on n and p nutrient and fertility degeneration . the results showed : ( l ) there are lots of factors which affect soil erosion and losses of n and p , in which rainfall and rainfall intensity were more important , while rainfall intensity is the most important meteorological phenomena factor
    针对当前黑土利用现状,本文借鉴众多学者的研究方法和观点,在吉林农大黑土区选择利用方式不同的玉米地、休闲地、果园、草地,在玉米区进行了不同数量的施肥,通过野外试验,采集一年自然降雨产流及泥沙样品,同时采集降雨前后的耕层土壤样品,研究了黑土区地表径流对氮磷养分特征及肥力退化的影响,结果表明:土壤侵蚀和氮磷的流失受诸多因素的影响,降雨量、降雨强度是重要因子,而降雨强度是影响农田地表径流养分流失的最重要的气象因子,特别是暴雨,暴雨径流中氮磷浓度较平时高得多;随作物生长,覆盖度逐渐增加以及不同利用方式下表现的覆盖度差异,氮磷流失都表现为显著的差异。
  • However , it lacks runoff data in absolutely most areas where culvert and small bridge locate . some traditional design method , such as the methods of statistic zone parameter , modification by catchment area , rainfall - runoff , reasoning formula and empiric equation et al , are used to estimate flood flow through culvert or bridge
    然而,绝大多数中小桥涵所在地却没有可利用的径流资料,通常采用统计分区法,面积改正法、暴雨径流法、推理公式和经验公式等传统设计方法,这些方法一般比较繁琐、精度较低、设计的流量偏大,导致工程造价偏高而浪费资金。
  • Climate in this valley changes sharply with vertical difference and rainfall increases with the height . calculation indicates that the design day rainstorm amount reaches 133mm , the rainfall intensity of day storm reaches 6 . 05mm / h , the design storm peak discharge is 239 . 7m3 / s and 753 . 0
    在计算泥石流峰值流量时,因考虑到泥石流固体物质的前期含水量、泥石流堵塞断流增加的暴雨径流量、泥石流间歇性阵流的迭加流量都会使泥石流流量增加,需要在计算公式中引入一个泥石流流量积累系数。
