Introduction to Dendritic Drainage Pattern

You will find different kinds of water bodies on the Earth and the origin of these bodies may be different and similarly the way they are drained, those patterns can also be different. If we talk about the Ganga river system that creates the world-famous plains, before draining into the Bay of Bengal, it follows a particular drainage pattern in its basin. There are different kinds of patterns or systems of drainage that can be found that water bodies usually follow. In this article, we will be discussing one of the most common patterns that are followed by the water bodies. This topic will help you to learn the river system and one of the most famous patterns. 


Introduction

If we talk about drainage, it is a process or a system or a way through which some liquid is being drained from one place to another. On the other hand, Geography or Geomorphology, if we talk about the drainage patterns or systems, they are a system followed by the rivers or streams or lakes etc. in a drainage basin. It is also called a river system as well and largely depends upon the irregularity of the tectonic plates or the rocks laying under the water body or the land gradient. Based on the Geology or topography of the region, the drainage patterns can be classified into several categories. One of them we're going to discuss below ie. dendritic drainage pattern, which is considered as one of the most important and common systems of drainage in Geomorphology.


Dendritic Drainage

It is one of the most common drainage patterns found in the world. It appears like branches of the roots of a tree and happens on that lithographic surface which has a uniform rock structure. It appears as a homogeneous structure and thus has a uniform and similar resistance towards the weathering and another phenomenon. In this kind of pattern, the tributaries usually join the larger stream at an acute angle which is less than 90°. The structure of the larger rivers along with their tributaries appears like branches of the tree and forms a V-shaped pattern.


The word " dendrites " has a Greek origin which simply means " of or like a tree ". It is also known as the Pinnate drainage pattern. There are a number of sub rivers that feed the main river and these sub rivers appear like branches. Sometimes, these tributaries also have further tributaries of their own. The rocks under the rivers have a particular structure and could be eroded equally in all directions. Dendrite rock is a kind of crystal that can be found in the regions where a tree-like structure is found.


The major examples of the rivers system that follows this dendritic drainage pattern are the Amazon river system which is found in South America, the Mississippi river system which is found in North America, the Ganga river system and the Indus river system which are found in Asia, etc. Besides these, mostly rivers found in Britain also follow this kind of pattern. The map of the Amazon river system is given below where you can see the Amazon River and its tributaries and also tributaries of the tributaries that combination makes this dendritic pattern.

Dendritic Drainage Pattern in India

India is known as a land of rivers where a number of large and small rivers are found and these follow different drainage patterns. Basically, all major types of drainage patterns can be found in India in different regions of the country. If we specifically talk about the Dendritic drainage pattern, it can be found in the Ganga Brahmaputra river system, Indus river system, Mahanadi or Godavari, etc. In the following map, the dendritic drainage pattern of the Ganga river can be observed.

Besides these, the rivers that follow antecedent drainage are the Indus, the Satluj, the Ganga, the Tista and the Brahmaputra. The rivers that follow the consequent system are Godavari, Krishna, and Kaveri. The examples of subsequent rivers are Chambal, Sind, Ken, Betwa etc whereas Damodar, Subarnarekha, Chambal, Bananas are examples of superinduced drainage. Besides these, trellis drainage, barbed pattern, rectangular drainage or radial pattern, annular and parallel drainage patterns are also found in India.


Conclusion

To sum up, the dendritic pattern is the system combinedly created by the major rivers and their tributaries and the formation of these rivers and their tributaries that appears like the branches of the tree and thus the name of the pattern is known as dendritic. We learned what is the meaning of the dendritic pattern of drainage and how it looks like and the various examples related to it that actually follow this pattern. This topic will not only increase your knowledge about one of the patterns of drainage followed by the rivers but will also help you in Geography or Geomorphology whenever you learn about rivers and the river systems or even whenever you study the maps. It will help you in identifying which particular river is following what kind of drainage patterns. 

FAQs (Frequently Asked Questions)

Question1. What do You Mean by Drainage? Define Dendritic Patterns. 

Answer. Drainage is basically a process or a system or a way through which some liquid is being drained whereas if we talk about the drainage patterns or systems, they are basically a system followed by the rivers or streams or lakes etc in a drainage basin and it is also called river system as well and largely depends upon the irregularity of the tectonic plates or the rocks laying under the water body or the land gradient. If we specifically talk about the dendritic pattern, it is one of the most common drainage patterns found in the world which appears like branches of the roots of a tree and happens on that lithographic surface that has uniform rock structure and thus has similar resistance towards the weathering and other phenomena. In this, the tributaries usually join the larger water body at an acute angle. The structure of the larger rivers along with their tributaries appears like branches of the tree and forms in a V-shaped pattern.

Question2. What Kind of Drainage Patterns are Found in India? Where is the Dendritic Pattern of the River Found in India?

Answer. If we talk about the drainage patterns or systems in Geography or Geomorphology, they are basically a system followed by the rivers or streams or lakes etc in a drainage basin. It is also called the river system. In India, there is a number of rivers found and these rivers follow different kinds of drainage patterns as per their Geology or topography such as antecedent drainage, consequent and subsequent rivers, epigenetic drainage, dendritic drainage, trellis, barbed, rectangular, radial, annular, parallel, and deranged drainage pattern. In India, if we talk about dendritic drainage patterns, the rivers which follow this system are the Ganga - Brahmaputra, the Indus river system, Mahanadi, Godavari, Krishna, etc. These rivers have different tributaries and form a structure that appears like branches of the tree.
