and Kalkalia, Bamutia, Fatikcherra along the
Lohar Nala will be highly vulnerable to flood
hazard. At that time the inundation depth will
increase up to 5 m which will affect 17–100
percent population of these mouzas (Table 15.3).
This level of inundation depth will overtop the
embankment of the right bank of the Haora River
and will spread in the Agartala town. Therefore,
the flood risk is high in these mouzas as well as
in Agartala in the 100 years return period.
This flood water level may take some days to
recede and after receding it will leave many
effects. Due to the damage of standing crops, as
well as agricultural land, it may cause food crisis
for many days and the price of the stored food
will be raised so much that it will become beyond
the ability of the people to purchase. On the other
hand, the people, whose houses will be fully
damaged, will become homeless for many days
and they will require more financial help to
rebuild their houses, as most of them belong to
extremely poor or poor category. They will suffer
from mental stress as well as financial crisis
because, on the one hand, they will lose their
standing crops which are their only source of
income, and on the other hand, flood water will
severely damage their houses which are their
only property. The owners of partly damaged
houses also require money to restore the damaged portions and thus, they will also remain
homeless until the renovation will be completed.
Due to the damage of roads, transport system will
be disrupted. So, it will be impossible to bring
necessary commodities from other states. There
