Most members of these communities are laborers, peasants and artisans belonging to backward
or scheduled castes. Many of them work on meager daily wages and debt bondage is their way of
life. When affected by the floods, they lost employment or their most valuable and often only
asset, the household.
Moreover, the disaster had a stark impact on the children, many of whom lost parents and other
family members. They were in a very fragile environment that negatively impacted their
physical, mental, and psychosocial development, and existing resources did not adequately meet
their needs. Also there were no such sincere efforts to comprehend the position life of flood
victims. No comprehensive study has been done in the above aspect generally human settlement
development and its future expansion. Very little effort is made to plan for the probable floods;
most of the studies are in disaster management and after flood emergency effort planning. Which
involves the immediate disposal of budget and implementation of measures unscientifically? 4

Hence a systematic approach is needed to understand the causes and consequence s of flood and
formulate effective measures against flood hazards.
STUDY AREA
In general most of the human settlements in Karnataka were established very near to the main
river course and other water bodies with less knowledge of probable disasters. This study will
investigate in a designated area of recent floods experienced in flood affected villages in Raichur
district of northern part of Karnataka under Krishna and Tungabhadra river basin.
In the recent devastating floods of October 2009 almost swept away 13 Districts of Karnataka
state i.e. Belgaum, Bijapur, Dharwad, Gadag, Haveri, Karwar, Gulgarga, Bidar, Raichur, Bellary,
Koppala, Bagalkote and Davangere. These floods created immense destruction of human life,
property and crops. It left a trial of death and destruction with lakhs of people losing their
belongings and their lives severely disrupted. The most destructive floods washed out several
villages on the river banks, 6.55 lakh houses were devastated and crops in over 22 lakh hectares
were inundated. 229 peoples lost their lives and 7882 live stocks perished. A total of 4292
villages were affected in various degree have caused a loss of over an estimated amount in
rupees 18,500 crores that include both public and privately- owned properties. In the post flood
