Abstract:
Flooding is one of the natural disasters generated by human activities which
constitute a threat to human life, property, and the built environment with high
impacts. Rapid urbanization and the growth of cities, especially in developing
countries like Sri Lanka, have led to the emergence of highly vulnerable semiurban
communities, particularly through informal settlements and inadequate
land management. Therefore, it is necessary to study how effected the flood
for sustainable development. The main objective of this research is, to
investigate the impact of flooding on sustainable development. The study is
carried out in Thekkawatta GN Division in the Kalutara Divisional Secretariat.
The mix method was used for this research. The primary data were collected
from 60 persons using a pre-tested questionnaire under the random sampling
methods. Apart from that 08 resources persons have been interviewed and
field observation was done to clarify the information. The data were analyzed
by using qualitative and quantitative methods. According to the analyzed lack
of construction of the canal, irregular construction of retaining wall of kalu
ganga, the growth of invasive plants, and sand mining was identified as threats
for the sustainable development of this area also, blocking the canal system by
peoples was an another weakness. Damaging roads, houses, furniture, and the
vehicles directly harm for the daily activity of the resident people of this area.
As an opportunity to flood the fertility rate of soil has developed and the
dumping site has cleared up. Therefore, the research suggests is the take action
to control the above problems with establishing the preparedness plan for
mitigating the flood in this area.
