坡地沖刷作用 的英文怎麼說
中文拼音 [pōdechōngshuāzuòyòng]
坡地沖刷作用
英文
hillwash-
( 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 、室內模擬降雨+放水沖刷試驗結果雨強小（如i 1 . 0mm min ）時，上游注入水量對戧坡侵蝕作用比降雨在戧坡上所產生徑流的侵蝕大；雨強大時（ i 2 . 0mm min ） ，上游水量下泄與當地降雨徑流一起增強對戧坡面的侵蝕作用，雨強越大，侵蝕作用也越大。The characteristic of top soil will changed by splash erosion and surface erosion, accordingly to alert the route of runoff and seepage and work to unconsistenty of soil erosion
棄土場坡面地表土壤特性隨著降雨擊濺和徑流沖刷的作用而發生變化，從而影響區域內徑流和滲流途經，造成坡面產流的不一致性。Through analysis, we conclude that washing action of wave and flow is main power of evolvement of region of interest landform, structure lead to the fact that water area around shallow structure in cheng dao sea field has an increase about 0. 3m / a through actual measurement, water depth increase rate around foundation is 0. 25m / a, slope gradient of side slope averagely has a decrease of 5 % o a year, however marine hydropower wash rate through compute is 0. 2m / a on underwater bottom, the wash rate on structure foundation is 0. 35m / a
分析認為，浪流的沖刷作用是研究區水深地形演化的主要動力，構築物的存在，使埕島海域淺水區人工構築物周邊水域實測年水深增加幅度約0 . 3m a ，地基附近水深增加速率0 . 25m a ，邊坡坡度平均每年以5減緩，而計算得出的海洋水動力沖蝕速率在水下底坡為0 . 2m a ，在構築物地基沖蝕速率達0 . 35m a 。By means of prototype observation, analysis with materials and theories, and laboratory test, the author deeply analyzed the causes and procedure of canal cross section erosion, and obtained eight causes which resulted the canal deform including flow, seepage, runoff, collapse of bank, dry effect, human activity, wave flush, frozen, and then stressed to discuss the frozen process
本文通過原型觀測、資料分析、理論分析、室內試驗對北引渠道變形的成因和發生機理進行了較為深入的分析研究，給出了造成北引渠道變形的八大原因：流水引起的變形、滲透引起的沖刷、地表徑流引起的沖刷、滑坡變形、乾燥作用、人類和動物活動的影響、風浪引起的沖刷、凍融侵蝕，並著重闡述了凍融侵蝕的機理。分享友人
