Refers to the river system of an area. If we look at any natural map, we will find that many small streams come from different directions and together form a main river, they flow into large parts of water like lake, sea or ocean, the amount of rainfall and relief. Forms of the drainage system. (The water area through which the river flows with its tributaries and forms the natural composition of that region, it is called the drainage system (basin) or drainage area of that river. Rivers are formed by erosion, flow and deposition of various shapes.
Rivers flow in different types of drainage patterns according to the structure of the land. On observing the river map of India, it is found that any high area such as mountain or high ground separates two neighboring drainage basins from each other. This type of high land is called water divider. Shiva joins the water area of one river to another river, then it is called river abduction. In the given map, see the flow sequence of the rivers of India, which river Where does it originate from and where does it fall into the sea?
Indian drainage system
Due to the difference in the surface composition of India, differences are visible in the drainage system. On this basis, Indian rivers can be divided into two classes,
- Himalayan rivers
- peninsular rivers
main rivers of the Himalaya Mountains The special thing is that water remains in them throughout the year. Apart from rain water to the rivers of this region, water is supplied to them due to melting of snow of high mountains. Coming from the mountainous regions, these rivers form deep gorges, gorges and springs and accumulate in the plains along with their mature stage. In the middle and lower parts, these rivers form the Visarpa, the Gokhur lake and the flood plain. Three major rivers originate from the Himalayas.
Indus River System
This system includes the Indus and its tributaries. The total length of the Indus river is about 2900 km. Is. Indus river flows forming a beautiful scenic gorge 500 meters high in the Ladakh district of Tibet. From here it flows south-west and enters Pakistan and finally joins the Arabian Sea. The five tributaries of the Indus are Jhelum, Chenab, Ravi, Km. Is. These are Sutlej and Beas, this region of five rivers is called Punjab. The amount of water flow is not the same throughout the year.
Ganga river system
The length of the river Ganga is 2500 km. More than. It is from Gangotri glacier. Near Haridwar, the Ganges leaves the mountainous part and enters the plains. It has other tributaries. These rivers form fertile silt plains. In these, river bend and Govar lakes are found, near Ambala, by a divider, the flow area of Ganga and Indus rivers. The Chambal Ken Betwa, Son and Damodar rivers flowing through the hard lands of peninsular India are also part of the Ganges system. Big dams have been built on these, from which hydroelectricity and irrigation are done. Flowing further south, the Ganges joins the Bay of Bengal forming a delta. The Ganges enters the main part of Bangladesh and after meeting with the Brahmaputra river, it is called Meghna. Brahmaputra River System The
Brahmaputra river system
has its origin near Mount Kailash and Lake Mansarovar. Flowing parallel to the Himalayan Mountains, it enters Arunachal Pradesh. Its flow in India is 1400 km. Is. Its tributaries are the Sohit Dhanshree Kalang etc. Due to the flow of more rainfall in the area, there are more depressions in it than comes later every year. The flow of rivers varies. River islands are also formed. In Bath it is known as snakes Brahmaputra in India and Padma and Meghna in Bangladesh. It flows into the Bay of Bengal forming a huge delta.
Rivers of Peninsular India
The specialty of the rivers of the Indian peninsula is that they are seasonal. Flows through arid region. Their length is also less than the rivers originating from the Himalayas. It does not form deep deposition grounds. The main water divide in peninsular India is formed by the Western Ghats, which lie from north to south near the west coast. Most of the rivers of the peninsular part like Mahanadi, Godavari, Krishna and Kaveri drain eastwards into the Bay of Bengal. This forms the delta. The rivers that flow west from the Western Ghats are small. Narmada and Tapi are the only two major rivers which flow westwards in the rift valley and join the Arabian Sea after forming the estuary.
originates from Amarkantak hill in Madhya Pradesh in a deep fault valley for 1312 km. It flows and falls into the Arabian Sea. Its flow area is in Madhya Pradesh and Gujarat, it forms Dhundhar Falls at Bhedaghat in marble rocks near Jabalpur, its tributaries are very small. All Types of River 2022
The Tapi river
originates in the Satpura mountain ranges in Madhya Pradesh from a place called Multai in Betul district, its length is 724 km. Is. Flowing in Madhya Pradesh, Maharashtra and Gujarat, it falls in the Gulf of Khambhat
It originates from the Western Ghats near Nashik for 1500 km. Flowing in Orissa and Andhra Pradesh, it falls into the Bay of Bengal. Its main tributaries are Wardha, Manjra, Ven Ganga and Pen Ganga. It has the largest drainage system among the peninsular rivers. Due to its large size and extent, it is also called Dakshin Ganga.
originates from a place called Sihawa in the highlands of Chhattisgarh. Its length is 858 km. Its drainage area is in Maharashtra, Chhattisgarh, Jharkhand and Orissa. Hirakud Dam has been built on this river.
The origin of this river is near Mahabaleshwar in Maharashtra. Its length is 1400 km. Is. It flows through Maharashtra, Karnataka and Andhra Pradesh. Its tributaries are Koyna, Panchganga, Malaprabha, Ghatprabha, Bhima, Musi and Tungabhadra. Almaty and Nagarjunasagar dams have been built on this.
originates from the Brahmagiri hill range of Coorg. Its length is 760 km. Is. Its tributaries are Hemavati, Amravati, Bhavani etc. Shivasamudram is its main waterfall. Hydroelectricity and irrigation are done from this river.
India is a peninsula which is surrounded by seas on three sides. The Indian Ocean extends to the south of India, to the west of the west coast is the Arabian Sea and to the east of the east coast is the Bay of Bengal. To the east of the Andaman and Nicobar Islands is the Andaman Sea. The Gulf of Mannar is situated between India and Sri Lanka. In the coastal part of Gujarat there are Gulfs of Khambhat and Kutch.
Role of rivers in the
country’s economy Rivers play an important role in the country’s economy. Agriculture takes place in the plains formed by the river. They supply clean drinking water. Earlier villages and towns were situated on their banks. Religious and cultural centers are located on its banks. By building dams, hydropower and irrigation are done from them. 4.6 River Pollution and Control
On the one hand we consider rivers to be holy, on the other hand we are polluting them. Waste from industries, dirty water from homes, throw dead animals into rivers. This increases pollution. The expansion of the hyacinth has also polluted the rivers. Rivers are the basis of our economy. Laws have been made by the government to solve the problem of pollution. Due to this, the flow of industrial waste into the rivers has been banned. Water from sewage lines is treated. Campaigns for cleaning the rivers have also been launched. People are also being made aware of this problem.
