  2. River - Wikipedia

    en.wikipedia.org/wiki/River

    The Lena river delta in Russia is formed from the river's sediment. While rivers may flow into lakes or man-made features such as reservoirs, the water they contain will always tend to flow down toward the ocean. [3] However, if human activity siphons too much water away from a river for other uses, the riverbed may run dry before reaching the ...

  3. Channel pattern - Wikipedia

    en.wikipedia.org/wiki/Channel_pattern

    Whether formed by chance or necessity, by headward erosion or downslope convergence, whether inherited or newly formed. [1] Depending on different geological factors such as weathering, erosion, depositional environment, and sediment type, different types of channel patterns can form.

  4. Channel (geography) - Wikipedia

    en.wikipedia.org/wiki/Channel_(geography)

    In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While channel typically refers to a natural formation, the cognate term canal denotes a similar artificial structure.

  5. Channel types - Wikipedia

    en.wikipedia.org/wiki/Channel_types

    A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.

  6. Stream - Wikipedia

    en.wikipedia.org/wiki/Stream

    A distributary, or a distributary channel, is a stream that branches off and flows away from a main stream channel, and the phenomenon is known as river bifurcation. Distributaries are common features of river deltas , and are often found where a valleyed stream enters wide flatlands or approaches the coastal plains around a lake or an ocean .

  7. Tributary - Wikipedia

    en.wikipedia.org/wiki/Tributary

    The water basin of the Wabash River; the other rivers (not including the Ohio River) are tributaries of the Wabash River. The Vermillion River (and its forks) is a highlighted example of a tributary of the Wabash River. The Wabash River is also a tributary of the Ohio River, which in turn is a tributary of the Mississippi River.

  8. River morphology - Wikipedia

    en.wikipedia.org/wiki/River_morphology

    The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...

  9. Bedrock river - Wikipedia

    en.wikipedia.org/wiki/Bedrock_river

    A bedrock river is a river that has little to no alluvium mantling the bedrock over which it flows. However, most bedrock rivers are not pure forms; they are a combination of a bedrock channel and an alluvial channel. The way one can distinguish between bedrock rivers and alluvial rivers is through the extent of sediment cover. [1]
