erosion caused by meaning in English
磨蚀原因
Examples
- In recent years , walls and fir saplings have been positioned around the valley to prevent erosion caused by excessive tree cutting in the past
近年来，墙（挡土）和枞树的树苗被用于山谷周围的护坡，以此来防止以前过度砍伐树木留下的后果。 - According to the investigation of the dykes in xinxiang reach of the yellow river , the annual volume of soil erosion caused by storm runoff amounted to 0 . 07 million cubic kilometres
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。 - 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。 - ( 2 ) the results of the rainfall - affected runoff scouring experiments in lab . when the rainfall intensity was less than l . omm / min , the soil erosion caused by the combination of rainfall and the upslope runoff was more than that caused by only the simulated rainfall . when the rainfall intensity was more than 2 . 0mm / min , the upslope runoff strengthened the effect of the runoff yielded in the local area on the dyke slope surface , and the effect increased with an increase of rainfall intensity
2 、室内模拟降雨+放水冲刷试验结果雨强小(如i 1 . 0mm min )时，上游注入水量对戗坡侵蚀作用比降雨在戗坡上所产生径流的侵蚀大；雨强大时( i 2 . 0mm min ) ，上游水量下泄与当地降雨径流一起增强对戗坡面的侵蚀作用，雨强越大，侵蚀作用也越大。
