2. CLASSIFICATION OF RESERVOIR

•Single Purpose Reservoirs

•Multi- Purpose Reservoirs

•System of Reservoirs


Reservoir Operation Schedule (ROS) is a scientific tool which helps to maintain the storage in reservoir and at the same time, avoids the risk of flood at down stream.

3. INTRODUCTION TO ROS, GOS

Gate Operation Schedule (GOS) is the sequence in which gates are operated so that required discharge is released safely.PPT Downloaded from http://www.pravinkolhe.com/

Emergency Action Plan (EAP) is a pre-decided procedure in which preventive measures are undertaken in case of emergency.

4. INTRODUCTION TO EAP

In short, ROS, GOS and EAP helps in safely release of flood without damage to structure, life and property on down stream of dam.

CONCLUDING REMARKS

The GOS for designed capacity is not yet tested. Although ROS is generally prepared in case of Flood

situations, it might be useful in case of water deficiency. It is observed that the ROS is prepared by referring the past

data which is based on the old methods of analysis. Now a days rainfall prediction is possible with help of

satellite observations and by performing rigorous analysis of meteorological data, using high speed computer, accurate prediction is of yield possible. Such techniques should be preferred for ROS and GOS.
