Engineering /Structural Measures

The engineering measures for flood control which bring relief to the flood prone areas by reducing flood flows and thereby the flood levels are –

(a) an artificially created reservoir behind a dam across a river

(b) a natural depression suitably improved and regulated, if necessary or

(c) by diversion of a part of the peak flow to another river or basin, where such diversion would not cause appreciable damage.

(d) by constructing a parallel channel bye passing a particular town/reach of the river prone to flooding.

The engineering methods of flood protection, which do not reduce the flood flow but reduce spilling, are:

(a) embankments which artificially raise the effective river bank and thereby prevent spilling and

(b) channel and drainage improvement works, which artificially reduce the flood water level so as to keep the same, confined within the river banks and thus prevent spilling.
