River and drainage system of Nagaland

<<–2/”>a >em>River and Drainage System of Nagaland

Nagaland, the smallest hilly state situated at the extreme north-eastern end of India, lies between 25° 6′ and 27° 4′ latitude, North of Equator and between the Longitudinal line 93° 20’ E and 95° 15’E.
The state Shares its boundary with Assam on the West, Myanmar on the East, Arunachal Pradesh and parts of Assam on the North and Manipur on the South.
The major rivers of Nagaland are Doyang, Dikhu, Dhansiri, Tizu, Tsurong, Nanung, Tsurang or Disai, Tsumok, Menung, Dzu, Langlong, Zunki, Likimro, Lanye, Dzuza and Manglu.
All these rivers are dendritic in nature.
As a river flows, it carries along material or debris, called its load.
A river’s load includes rocks, stones and other large particles, which are washed along the river bed. Finer particles float in the water.
A river grows larger as it collects water from more tributaries along its course. The river ends at a mouth.
In larger rivers there is often also a wider floodplain shaped by flood waters over-topping the channel.
Floodplains may be very wide in relation to the size of the river channel.
Nagaland is dissected by a number of seasonal and perennial rivers and rivulets.
Of the rivers, Dhansiri, Doyang and Dikhu flow westward into the Brahmaputra.
The Tizu River, on the other hand, flows towards east and joins the Chindwin River in Burma.

DOYANG

It is the longest river in the state originating from the Japfü Hill near the Southern slope of Mao in Manipur and moves in a south west direction passing through Kohima district and flows northward into Zunheboto and Wokha District.
It passes through a great part of Wokha District and flows south westerly into Dhansiri in Sibsagar, District of Assam.
The main tributaries of Doyang are Chubi River which flows southward from Mokokchung District and Nzhu River, originating from Nerhema area of Kohima district and flows through Miphong in Tseminyu area and finally pours itself to Doyang.

DIKHU

River Dikhu, which has a total length of about 160 km, originates from Nuroto Hill area in Zunheboto district.
The river traverses towards north along the border of Mokokchung and Tuensang districts.
The main tributaries of river Dikhu are Yangyu of Tuensang district and Nanung in the Langpangkong range in Mokokchung district.
The river flows further northward and leaves the hill near Naginimora and finally merges with the Brahmaputra River in the plains of Assam.

DHANSIRI

Dhansiri flows through the southwestern part of the state through Rangapahar-Dimapur Plains of Dimapur District.
This river receives almost all the western and southern drainages of Nagaland.
Its main tributaries are river Dzuza and Diphu.
At the extreme southwest of the state, it assumes a northwardly course forming a natural boundary with North Cachar Hills of Assam which finally drains into the Brahmaputra.

TIZU

The Tizu River forms an important drainage system in the eastern part of the state.
It originates from the central part of the state and runs through a northeast direction flows through Zunheboto, Phek district and empties itself in the Chindwin River of Myanmar.
The main tributaries of River Tizu are river Zunki, Lanye and Likimro.

MILAK

Milak is another important river which flows through Mokokchung District.
One of its main tributary is Tsurong.

ZUNGKI

The Zunki River which is the biggest tributary of Tizu, starts from the northeastern part of Changdong forest in the south of Teku and flows in southernly direction towards Noklak, Shamator and Kiphire and finally joins Tizu below Kiphire.

River and drainage system of Nagaland

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 the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land.

River is the biggest source of water.
Rivers provide water to drink, Irrigation, electricity, cook, clean things and easy & cheap transportation.
It is also a source of fresh water that flowing naturally towards an ocean, lake, sea or another river.
Rivers flow in channels.
The bottom of channel is called the bed and sides of the channel are called the banks.
Sometimes a river flows into the ground and becomes dry at the end of its course without reaching another body of water.
Rivers begin at their source in higher ground such as Mountains or hills, where rain water or melting snow collects and forms tiny streams.
When one stream meets another and they merge together, the smaller steam is known as a tributary.
It takes many tributary streams to form a river.

Nagaland is a state in north-eastern India. It is bordered by Assam to the north and east, Manipur to the south, and Myanmar to the west. The state has a Population of over 1.9 million people and a land area of 16,579 square kilometers.

Nagaland is a mountainous state with a highland plateau in the centre and lower hills and valleys in the north and south. The state is drained by a number of rivers, including the Brahmaputra, the Chindwin, and the Barak.

The Brahmaputra is the largest river in Nagaland. It originates in the Himalayas and flows through Assam, Nagaland, and Arunachal Pradesh before entering Bangladesh. The Brahmaputra is a major source of water for irrigation and drinking water in Nagaland.

The Chindwin is a river that originates in the Himalayas and flows through Myanmar and Nagaland. It is a major tributary of the Irrawaddy River. The Chindwin is a major source of water for irrigation and drinking water in Nagaland.

The Barak is a river that originates in the Himalayas and flows through Manipur, Assam, and Nagaland. It is a major tributary of the Brahmaputra River. The Barak is a major source of water for irrigation and drinking water in Nagaland.

The rivers of Nagaland are important for the state’s economy and Environment. They are used for irrigation, drinking water, and transportation. The rivers are also home to a variety of fish and other aquatic life.

However, the rivers of Nagaland are facing a number of threats, including pollution, deforestation, and Climate change. Pollution from industries and agriculture is contaminating the rivers. Deforestation is leading to Soil erosion and sedimentation in the rivers. Climate Change is causing the rivers to become more erratic and flooding is becoming more common.

These threats are having a negative impact on the rivers and the people who depend on them. The government of Nagaland is taking steps to address these threats, but more needs to be done to protect the rivers of Nagaland.

One of the most important things that can be done to protect the rivers of Nagaland is to reduce pollution. This can be done by enforcing environmental regulations and by educating people about the importance of keeping the rivers clean.

Another important step is to protect the forests. Forests help to prevent soil erosion and sedimentation in the rivers. They also help to regulate the flow of water.

Finally, it is important to adapt to the effects of climate change. This includes building flood defences and developing drought-resistant crops.

By taking these steps, the government of Nagaland can help to protect the rivers of Nagaland and the people who depend on them.

What is a river?
A river is a natural watercourse, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers are called creeks or streams.

What is a drainage system?
A drainage system is a Network of rivers, streams, and other watercourses that collect and carry water from the land to the ocean or another body of water. The drainage system of a region is determined by the geology of the area, the climate, and the vegetation.

What are the different types of rivers?
There are three main types of rivers: perennial, ephemeral, and intermittent. Perennial rivers flow year-round, while ephemeral rivers only flow during the rainy season. Intermittent rivers flow only during certain times of the year, such as during the spring snowmelt.

What are the different types of drainage systems?
There are three main types of drainage systems: dendritic, radial, and trellis. Dendritic drainage systems are the most common type of drainage system. They are characterized by a branching network of rivers that resembles the branches of a tree. Radial drainage systems are found in areas with a central mountain range. The rivers in a radial drainage system radiate outward from the mountain range. Trellis drainage systems are found in areas with parallel mountain ranges. The rivers in a trellis drainage system flow parallel to the mountain ranges.

What are the benefits of a river?
Rivers provide many benefits to humans and the environment. They provide water for drinking, irrigation, and Industry. They also provide transportation, recreation, and habitat for wildlife.

What are the challenges of a river?
Rivers also face many challenges. They are often polluted by human activities, such as agriculture, industry, and sewage. They are also threatened by Dams, which can disrupt the flow of water and damage the river ecosystem.

What is the future of rivers?
The future of rivers is uncertain. They are facing many challenges, but they also provide many benefits. It is important to protect rivers and manage them sustainably so that they can continue to provide these benefits for future generations.
