runoff erosion meaning in Chinese
径流侵蚀
Examples
- Based on the analysis of the data and information from the field observations and lab experiments , the results were as follows : ( 1 ) the results of the simulated rainfall and runoff erosion experiments in lab . under the design experiment conditions including the constant rainfall intensities of 1 . 0 , 2 . 0 , 3 . 0mm / min and the rainfall durations of 30 , 70 minutes and with soil moisture content 9 . 5 % or 10 . 0 % for dry situation , as well as with the soil moisture content 19 . 0 % or 20 . 0 % for wet situation , the soil erosion increased nonlinearly with the rainfall intensity , and the rainfall duration . the results of the experiments indicated that the amount of soil erosion caused by the simulated rainfall and runoff on the dry - soil slope was more than that on the wet - soil slope
通过实地观测及室内试验资料分析，得到如下研究成果： 1 、室内模拟降雨径流对戗坡的侵蚀试验研究结果在定雨强为1 . 0 、 2 . 0 、 3 . 0mm min ，降雨历时30 、 70分钟，干土含水量为9 . 5 10 . 0 ，湿土含水量为19 . 0 20 . 0的条件下，侵蚀量与雨强成非线性正比关系；雨强大，侵蚀量大；降雨历时长，侵蚀量也大；堤坡含水量大时，侵蚀量小，堤坡含水量小时侵蚀量大。 - The hillslope erosion processes include soil separation , sediment transport and sediment precipitate , which these three process result from the rainfall splash erosion and runoff erosion . to study and analyze the happening and developing conditions of hydraulic , soil and terrain , and the mechanisms of transitions and influences of these processes each other is the prerequisite to set up physical model of soil erosion
坡面侵蚀过程包括降雨溅击和径流冲刷引起的土壤分离、泥沙输移和沉积3大过程，研究和分析这些过程发生、发展的水力、土壤、地形条件以及各过程间相互转化、相互影响的机理，是建立土壤侵蚀物理模型的前提条件。 - 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。
