河道展寬 的英文怎麼說
中文拼音 [hédàozhǎnkuān]
河道展寬
英文
channel widening-
Then river width increased and the intensity of deep point lowing and bed material coarsening decreased and water level lowed continuously. so the bed form changed toward to u type. the bed regulation is realized through sediment silting in different parts in cross section during silting period and the deformation of bed form changed from broad u type channel to narrow and deep v type channel
研究表明，河道在持續沖刷前期深泓點及水位下降與河床粗化同步發展，河床向v型發展；沖刷後期深泓點下降、河床粗化減弱，河道展寬增大，水位繼續下降，河床向u型發展；在以淤積為主時期的調整，是通過斷面不同部位的淤積來實現的，但都是由u型較大河槽向v型窄深小槽發展。Northeast faults control the spread of the anhui riverway, and eastwest faults resulted in the widening of the river and the occurrence of nodes, then the stream raised and the riverway turn into goose pattern braided river. northwest faults and northsouth faults influence the evolvement of partial riverway, for example, the northwest lujiang - zhongming fault influence the evolvement of tongning shoals, and the northsouth faults passing through zongyang - digang make the riverway ' s direction from north - east to north - south
北東向斷裂構造控制了皖江河型的展布；東西向斷裂構造影響河道的拓寬，形成磯頭，磯頭挑流進一步使河道形成穩定的鵝頭型；北西、南北向斷裂影響局部河道的發育演變，如北西向廬江-鐘鳴斷裂影響銅陵沙洲的發育演變，南北向斷裂影響樅陽、銅陵、獲港河道使其延伸方向由北東轉向南北向。This text is by way of would rather analyses the yellow river hydrology silt characteristic, river course property of ningmeng as well as after the long liu reservoir application to the influence of meng heduan, the importance would rather to have expounded that train in the ning meng river course. by way of analysing the present situation of the ningmeng course river course management and father, and puts forward the major problem that exists, and carries on corresponding countermeasure research be dead against these problems. according to property and the engineering present situation of river course, engineering experience and the correlation theory are used, to renovates the principle and renovates the scheme and the measure has carried on the analysis research of overall system
