1·As a result of fluvial scouring and aggrading the riverbed, the alluvial layer is fluid-saturated porous medium.
由于河流冲刷和河床加积，沉积层多饱和多孔。
2·The research in fluvial sedimentology is significant not only for theory but also for practice of mine production and flood controlling.
河流沉积学的研究不但具有重要的理论意义，而且对生产实践和洪灾防治具有重要的指导作用。
3·The surface erosion and fluvial silt in upper reaches of Changjiang River were analyzed systematically.
本文系统的分析研究了长江上游地面侵蚀和河流泥沙两个系统。
4·It is also not suitable for the deposits formed in sedimentary environments such as firths, tidal zones and fluvial deltas.
在河口湾、潮间带和河流三角洲前缘环境中形成的沉积体也不适合进行构型单元分析。
5·Abundant in natural gas sources, Jurassic Shaximiao Formation in west Sichuan Basin is a red sandstone and shale mainly deposited in fluvial, deltaic shoal faces.
四川盆地西部侏罗系沙溪庙组是河流—三角洲—滨浅湖沉积为主的红色砂泥岩系，天然气资源相当丰富。
