The river is the rudimentary lifeline of the ecosystem and ultimately the important
facet of the prominent life forms of the land lock vicinities. Many successful
civilizations took place nearby the rivers like Nile. In the modern days too, cities like
London also flourished on the bank of river Thames.
A river has the potential to bring life with it and also create a whole new ecosystem at
its will. So, it becomes our obligation to care of the rivers. Unfortunately, many of the
contemporary urban places are evolving to make major perils to the rivers and its
The river Naika, passing through Tangla is currently suffering from the ominous
consequences of on going human activities in Tangla and its surrounding areas.
To find out the solution for
improvising the ailment of the
of Naika river with reference to
the biodiversity of the riverine
To up rise a balance between
the urban development and the
riverine ecosystem of Naika.
To encourage the people to
come up with ideas, techniques
and suggestions to diminish
waste disposal in Naika river.
With the continuous rise of population the need for resources also have increased
considerably. As a result, the production of waste has gone up to a large extent. This
has made it necessary to improvise and upgrade the waste management system to
get rid from this serious issue.
During monsoon, the river Naika is observed to be high on current and its water level
rises to about 8 feet flooding the adjacent streets and residential areas. This causes
the waste materials on its bank to flush away making the river dirty.
Flooding on the banks of the river causes erosion of soil and subsequently the river
bed is rising silently.
Due to the poor water quality, the local people who could earlier utilize the water from
this river for their daily uses, are now afraid of using the water as they reported to
suffer from itching and other skin infection in contact with this water.
Throwing waste materials into the
river has divested the water quality
of the river.
Faults and negligence of the
drainage system from the
residential areas outlets all the
wastes from homes directly into the
The jeopardized construction of
bridges and other infrastructures
along the river side has led to mix
huge amount of sand, cement and
other construction materials to the
Sewage, garbage and waste from households, shops etc. are dumped
into rivers at very large scale. These wastes contain many chemicals
and poisonous substances which are very harmful to plants and
animals dependent on the river water and living in it.

CHARACTERISTICS OF NAIKA RIVER
CHARACTERISTICS OF NAIKA RIVER
The river originates from Kachubil Tea Esate near Paneri
The river flows through Paneri, Sastrapara, Jalukbari, Tangla and
Tokankata covering a distance of approximately 16 kms.
At Tokankata river Naika recieves a tributary “Hurduma” (slightly
smaller in size than Naika) and finally flows to fall in to river Nonai,
which is roughly fouir times larger in size than Naika.
After that they move together towards south up to Mangladoi and fall in
to mighty Brahmaputra.
Digging down silt settled at the river bed.
Installing proper waste disposal system all across the residential areas near the
Setting up guard walls along the river laterals.
Improvisation and upgradation of the faulty drainage system.
Minimization of river bank erosion of Naika river is a prime need.
Protection of the surrounding residential area of the river Naika from
calamities like flood is necessary.
To protect the riverine ecosystem that presides in the Naika river.
To improve the water quality so that it becomes suitable for human use.
To keep the biodiversity of the river ecosystem in a manner so that the
aquatic life forms can survive in the river.
