This report describes the Brahmani-Baitarani river basins and their
flood risks, and proposes plans for reducing flood risks using a mixture
of structural and non-structural measures. It begins by describing the
geophysical and hydrological characteristics as well as recent flood
history. Importantly, it does so from a macro-perspective as well as
from the perspective of communities living in the flood-prone areas. A
flood risk assessment is given of the current situation as well as under
potential climate change conditions for the years 2040 and 2080.
Subsequent chapters elaborate the gamut of existing and possible future
flood mitigation measures. As well as embankments, dams and river
offtakes, non-structural elements such as flood forecasting, land use
management, community level measures, agricultural adaptations and
reservoir optimization techniques are discussed. The urban environment
is also taken into consideration, for which drainage designs and
costings are described. The economic and environmental considerations of
all these interventions are presented. Finally the report spells out the
necessity of improvements in institutional and community activities in
order to create a better enabling environment for flood management.
This report makes no decisions, but gives choices and options, which
will work best when implemented in harmony. Not all options may be
economically or socially feasible. This requires further study and
discussions between stakeholders. It is hoped that this report may
assist in these discussions, leading to an integrated approach that will
help mitigate the recurrent flood problems in the Brahmani-Baitarani
basins, for the benefit of millions of people living in these fertile
but yet hazardous environments.
