岸灘演變 的英文怎麼說
中文拼音 [àntānyǎnbiàn]
岸灘演變
英文
shore process-
According to the contrast between different maps and the dynamical conditions, the area of bohe lagoon had reduced by 45. 3 % from 1932 to 2000 and human activities in the coastal zone, such as inning, sand dredging and aquiculture, have brought great effects on the coastal system, which has accelerated the barrier erosion and lagoon evolvement
通過對比分析， 1932 ~ 2000年，博賀?湖面積減少45 . 3 % ，人類活動已成為影響該區海岸演變的主導因素；灘塗圍墾、海岸采沙與水產養殖等人類活動加劇了沙壩海岸的侵蝕後退，且使得?湖面積迅速減少，不斷淤淺萎縮，大大加快了海岸體系的演化進程。This paper presents a method of probability analysis in order to develop the general design and analysis methods for problems of the embankment stability under random storm wave actions as well as with random properties of the embankment medium. the major purpose of this study is carry out modellings of ( 1 ) probability analysis for the problem of seepage stability of levee projects ; ( 2 ) probability analysis for the problem of erosion due to washout sediments from the embankment ; ( 3 ) numerical analysis for coastal evolution due to beach erosion under energy actions of storm wave
本文根據598084號年浙江省自然科學基金項目和g59901號國家教育部回國留學人員科研啟動基金項目的部分研究目標和研究內容的要求應用概率分析方法研究了在隨機風浪荷載作用下和築堤材料隨機性影響下防護堤壩抗滲流、抗沖刷穩定性的分析計算模型；用數值分析方法研究了在浪潮能量作用下岸灘侵蝕造成海岸演變問題的數學分析模型。It is concluded that the phenomena of replacement of spatial and temporal process is typical in the erosion development, the coarsen of riverbeds, the sediment concentration and the change of river regime, etc
分析表明，河流再造床過程在沖刷延展、河床粗化、含沙量及其特徵、岸灘侵蝕以及河型變化等方面具有較典型的時空演替現象。
