Achievement in Flood Management

Floods being a natural phenomena, total elimination or control of floods is neither practically possible nor economically viable. Hence, flood management aims at providing a reasonable degree of protection against flood damage at economic costs.

In India, systematic planning for flood management commenced with the Five Year Plans, particularly with the launching of National Programme of Flood Management in 1954. During the last 48 years, different methods of flood protection structural as well as non-structural have been adopted in different states depending upon the nature of the problem and local conditions. Structural measures include storage reservoirs, flood embankments, drainage channels, anti-erosion works, channel improvement works, detention basins etc. and non-structural measures include flood forecasting, flood plain zoning, flood proofing, disaster preparedness etc.

The various flood management measures undertaken through the successive five year plans are summarized below :-

1.

Flood embankments

34397.61 km

2.

Drainage channels

51317.50 km

3.

Towns protection works

2400 Nos.

4.

Villages raised

4721 Nos.

 

Reservoirs constructed with exclusive flood control storage include Maithon, Panchet, Tilaiya and Konar in Damodar Valley; Chandil dam on Subarnarekha river and Rengali dam on Brahmani river. In addition, a live storage of 177 billion cubic meter created so far in the various reservoirs for irrigation, hydropower generation, drinking water etc. also help in reducing flood intensity by storing part of the flood waters in them.
