Therefore it is important to evolve flood management technique so as to minimise loss of lives and property on account of release of water from the dam and also to store the flood water in the reservoir.
Two types of measures
[A] Structural measures:
[B] Non-structural measures
Flood plain zoning
Among the above measures, the non-structural measures particularly flood forecast is more important The need of hydrological forecasts is more and more felt and reliable forecast service becomes a necessity both for a means of flood damage reduction and reservoir regulations.

Duties of flood operator : Sitting in the chair of operation of flood, the followings are to be kept in mined. (i) P W L (ii) Present storage. (iii) Any warning from IMD, CWC or from other authority for rainfall, flood etc. (iv) Rule level of the particular day. (v) Cushion available in the dam w.r.t. rule level & F R L. (vi) Present inflow / outflow.
For effectively reservoir operation, the operation of flood shall keep the following details in mind.
Fully acquivant with the basin.
Size, type, extent.
General slope, vegetation cover.
Distance from the dam site.
Representation catchments area.
Communication of rainfall data to dam site, flood control cell.
River gauging station:
Correlate the gauge level and its river discharge.
Details of upstream dam (if any) w.r.f. its storages, max. release capacity, travel time of flood from U/S dam to our dam site, arrangement of communication of release of flood.
