The recent Kosi floods have proved once again that inadequate control measures have been responsible for the recurring disasters. Typically flood control and riverine studies focus on hydrological information, whereas a much more integrated approach that pays attention to specific morphological factors is required. Since Kosi is a dynamic river with a unique morphology and because it is a river which has always carried high sediment loads, flood management strategies must be attuned to such specific parameters of the river, besides being much more than mere "river control" through embankments.
