Abstract:
Monsoon is the major source of water for agriculture,
drinking water as well as other sectors of water demand
in INDIA. But on the other hand, it also causes the
problems for Indian megacities due to urban flooding.
Urban flooding is a type of flood which flooded the
urban areas. There are many factors which are
responsible for the urban flooding such as low-lying
topography, heavy rainfall, unplanned urbanization and
improper drainage system. Among these improper drainage
systems play a crucial role for creating havoc situation
of flooding in the megacities. Drainage systems are the
major source of conducting waste water and also rain
water. But, due to sedimentation, siltation and poor
management, these systems fail. Therefore, in the
monsoon period, drainage system overflows and the
surrounding areas become flooded. The present study is
an attempt to describe the role of drainage system in
creating and mitigating the problem of urban flooding in
the Lucknow city. Lucknow is the most populated
metropolitan city of Uttar Pradesh. River Gomati is the
major source of water for the city. There are total 28
drains meet with river Gomati at different places. The
severe flooding in Lucknow city is believed to originate
from insufficient drainage capacity and blockages of the
drainage system due to huge volumes of garbage and
polyethylene bags. Out of the 28 drains about 20 drains
are choked and silted. Many of old drains and
waterbodies have been turned into urbanized area. All
these factors trigger the problem of flooding in the
city. Therefore, the need of the time is to generate
strategy which includes proper planning, guideline and
management for drainage system. In the present study we
collect information of all old drains and waterbodies
through Survey of India toposheet and compare this data
from present satellite data. In this way we have a
complete scenario of drainage system of the city which
indicates that there are many waterbodies and drains
have been choked. Thus desiltation and rejuvenation of
waterbodies and drain would be remedial measures for
tackling of urban flooding problem.
