dendritic drainage. oxford. views updated. dendritic drainage A drainage pattern that may develop on homogeneous rock, which has a shape resembling the pattern made by the branches of a tree or the veins of a leaf. A Dictionary of Ecology.
Also asked, what is a dendritic pattern?
Dendritic refers to a shape that resembles a branch tree. It is a pattern that is associated with growth or movement. Consider how the main trunk of a oak forks into large limbs that form again and again into smaller branches and twigs.
Secondly, why do dendritic drainage patterns form? Dendritic drainage pattern They develop where the river channel follows the slope of the terrain. Dendritic systems form in V-shaped valleys; as a result, the rock types must be impervious and non-porous.
Similarly, it is asked, what is radial drainage?
Definition of radial drainage pattern. A drainage pattern in which consequent streams radiate or diverge outward, like the spokes of a wheel, from a high central area; it is best developed on the slopes of a young, unbreached domal structure or of a volcanic cone.
What are the four types of drainage?

Where are dendritic drainage pattern found?
Dendritic patterns, which are by far the most common, develop in areas where the rock (or unconsolidated material) beneath the stream has no particular fabric or structure and can be eroded equally easily in all directions. Examples would be granite, gneiss, volcanic rock, and sedimentary rock that has not been folded.
What is barbed drainage pattern?
Barbed Drainage Pattern is a drainage pattern wherein tributaries form obtuse angles with the main stream; they appear to point up-river. This is due capture that has caused the main stream to flow in a direction opposite to its original one.
What do you mean by drainage?
Drainage is the process in which water leaches downward from the upper soil layers to lower layers, or how surface water is removed. In nature certain minerals such as sand provide rapid drainage, while heavy minerals like clay can restrict drainage.
What is rectangular drainage?
Definition of rectangular drainage pattern. A drainage pattern in which the main streams and their tributaries display many right-angle bends and exhibit sections of approx. the same length; it is indicative of streams following prominent fault or joint systems that break the rocks into rectangular blocks.
What is river pattern Class 9?
Drainage Patterns: The stream and its tributaries resemble the branches of a tree. Hence, it is called dendritic pattern. Radial Drainage Pattern: When the streams flow in different directions from a central peak or dome like structure, a radial pattern is developed.
What are the functions of drainage?
The function of the field drainage system is to control the water table, whereas the function of the main drainage system is to collect, transport, and dispose of the water through an outfall or outlet. In some instances one makes an additional distinction between collector and main drainage systems.
Which is the most common type of drainage pattern?
What are drainage features?
Natural drainage features include lakes, rivers, swamps, sea, rapids, water falls, cataracts, springs, deltas, fjords, sand or mud, and bays.
What is the difference between a radial and centripetal drainage pattern?
Distinguish between Radial and Centripetal drainage. Radial drainage : When the rivers radiats from a hill, the pattern is called radial. Centripetal drainage : The rivers flowing into a depression or a lake, is called a centripetal drainage. An area drained by a river and its tributaries is called a drainage basin.
What is the meaning of radial pattern?
Radial refers to the pattern that you get when straight lines are drawn from the centre of a circle to a number of points round the edge.
What is drainage network?
Drainage Network. a network of channels and drains constructed on marshy or excessively wet land. It is the key element of a drainage system and consists of regulating, protecting, and conducting networks with drainage outlets, manholes, overfalls, chutes, bridges, pipe crossings, and other such structures.
What is the meaning of drainage system?
In geomorphology, a drainage system is the pattern formed by the streams, rivers, and lakes in a particular drainage basin. A watershed represents all of the stream tributaries that flow to some location along the stream channel.
Which of the following is an example of radial drainage pattern?
Radial Drainage Pattern Kilimanjaro. A good example of a radial drainage pattern is provided by the rivers originating from the Amarkantak Mountain. Rivers like Narmada, Son and Mahanadi originating from Amarkantak Hills flow in different directions and are good examples of radial pattern.
What is surface drainage?
Surface drainage is the removal of water that collects on the land surface. A surface drainage system consists of shallow ditches and should include land smoothing or land grading. This type of system is suitable for all slowly permeable soils and for soils with fragipans or clay subsoils.
