A riverscape [1] (also called river landscape) [2] comprises the features of the landscape which can be found on and along a river. Most features of riverscapes include natural landforms (such as meanders and oxbow lakes) but they can also include artificial landforms (such as man-made levees and river groynes). Riverscapes can be divided into ...
Landforms related to rivers and other watercourses include: Channel (geography) – Narrow body of water; Confluence – Meeting of two or more bodies of flowing water; Cut bank – Outside bank of a water channel, which is continually undergoing erosion; Crevasse splay – Sediment deposited on a floodplain by a stream which breaks its levees
Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type.Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains ...
A river delta is so named because the shape of the Nile Delta approximates the triangular uppercase Greek letter delta.The triangular shape of the Nile Delta was known to audiences of classical Athenian drama; the tragedy Prometheus Bound by Aeschylus refers to it as the "triangular Nilotic land", though not as a "delta".

Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is ...
The headwaters of a river are the smaller streams that feed a river, and make up the river's source. [4] These streams may be small and flow rapidly down the sides of mountains . [ 5 ] All of the land uphill of a river that feeds it with water in this way is in that river's drainage basin or watershed. [ 4 ]
[54] [55] Rivers are key links in the connectivity of different landscape elements. As rivers flow across the landscape, they generally increase in size, merging with other rivers. The network of rivers thus formed is a drainage system. These systems take on four general patterns: dendritic, radial, rectangular, and trellis.
The stream order or waterbody order is a positive whole number used in geomorphology and hydrology to indicate the level of branching in a river system.. There are various approaches [1] to the topological ordering of rivers or sections of rivers based on their distance from the source ("top down" [2]) or from the confluence (the point where two rivers merge) or river mouth ("bottom up" [3 ...
