河床河床riverbed河谷中平水期水流所占据的谷底部分。又称河槽。河床横剖面呈一低洼的槽形。纵剖面，在山区较陡，深槽与浅滩交替，多跌水、瀑布；平原区坡度较缓，微有起伏。平面形态：山区河床多狭窄顺直，岸线因山嘴突出而呈犬牙交错；平原区河床多弯曲或分汊。河床纵剖面是从河源到河口的河床最低点的连线。该纵剖面的发展，受河流侵蚀基准面的控制。河流的下切面是无止境的，往往受某一基面控制，河流下切到接近这一平面后即失去侵蚀能力，不再向下侵蚀，这一平面称为河流侵蚀基准面。影响河床纵剖面发展的因素有气候、构造、岩性及环境变迁等。河床河床的类型一般可分为4类：①顺直微弯型，河段顺直略有弯曲、深槽、浅滩交错分布。②弯曲型，具有曲折的外形和蜿蜒蠕动的动态特性，分布很广，任意两相邻浅滩的间距约为河宽的5～7倍。③分汊型，又称江心洲型河床，具有一个或几个江心洲，河身呈莲藕状，具两股以上的汊道，汊道交替消长。④游荡型，河身顺直宽浅，沙滩众多，汊道交织，河床变形迅速，主槽摆动不定，水流散乱。河床在水流作用下形成河床侵蚀地貌和堆积地貌。侵蚀地貌主要有深槽、壶穴、岩槛、深切曲流。当水流侵蚀能力增强，该段河床就被冲刷成深槽。在构造破碎带，节理发育与被湍急水流冲磨成的深穴称壶穴。可深达6～7米。横亘于河床底部上凸的坚硬岩石组成的坡坎称岩槛，常伴有瀑布或跌水。由于地壳抬升，深切到基岩之中的曲流称深切曲流。河床堆积地貌主要有河床展宽期间堆积的浅滩；布于岸边的边滩；布于河心的心滩，枯水位时露出水面，中水位以上出露的称江心洲。沿岸长条延伸的沙滩称沙嘴。边滩经生长，发育成河漫滩。河漫滩上随着动力作用的变化而发育多种类型的微地貌。（见河漫滩）
