The weser estuary in germany, with broad beaches, lots of sand bars and many tributaries, is characterized with a great quantity of sediment transport due to tidal current ' s movement in the fluvial bed of fine sediment
摘要德國威悉河口灘地寬廣，有無數的沙洲和許多大的分流，潮流在主要為細沙的沖積河床中運動，泥沙輸移量極大。 -
It is suggested that the distribution of the depositional systems and the depositional facies have the clear characteristic that in the north of the research area, the alluvial fan sediment, the fluvial system and the delta system are the main styles of the depositional system, towards to the direction of basin the lacustrine, the barrier, the carbonate ramp system become the main depositional systems
受海平面升降變化控制，區內沉積體系和沉積相的分佈具有明顯的分帶性，北部靠近源區以沖積扇或河流及三角洲沉積為主，向盆地方向以湖泊或海岸障壁-瀉湖、碳酸鹽緩坡沉積為主。中二疊世北部源區發生構造抬升，當時古氣候逐漸乾燥，成煤環境結束，沉積物以陸相河流、湖泊三角洲占優勢。 -
It is suggested in this paper that the sediment of the high stand system tract is mainly composed of fine - grained sediment, hardly of the large scale of fluvial - delta because of the low dip of the ramp, low subsiding rate and low sedimentary rate in basin
研究表明，盆地基底沉降幅度小、坡度極為平緩、沉積速率很低，因此導致層序內的高位體系域多以細碎屑沉積為主，大型河流三角洲沉積基本不發育。 -
Based on the measured field data the interaction between water and sediment and river boundary in fluvial rivers was illuminated in this research. the understanding on the law of river variation and flooding in wide and shallow reach in the lower yellow river was improved. this research can direct the flood defense in the lower yellow river in some extent
本項研究以實測資料為基礎，闡明了沖積性河流水沙條件與河道邊界條件的相互影響和相互塑造，深化了對黃河下游寬河段河床演變及排洪規律的認識，對下游防洪具有較高的指導作用。 -
Pi formation is combination of thick sand body, because the sediment mode of reservoir in changyuan of daqing is mainly combined of great leaf delta and partly fluvial facies, about 500m thick, combined of 130 little sand or mud layers, which is typical heterogeneity reservoir, the reservoir ' s character is greatly distribute, high permeate and serious heterogeneity
Pi油層組是厚油層組合，由於大慶長垣儲層的沉積模式以大型葉狀三角洲及部分河流相為主，總厚度500多米，由130多個小砂層和泥巖交互而成，是一套典型的非均質砂巖儲層，該儲層具有分佈廣、厚度大、滲透率高和層內非均質性嚴重等特點。
