The document discusses the Jayakwadi Project located in Paithan, Aurangabad. It provides details of the project such as its location, catchment area, gross storage, dam height and length, spillway details, submergence area, construction details, and power generation. It also discusses reservoir operation schedule (ROS), gate operation schedule (GOS), and emergency action plan (EAP) and how they help ensure safe release of flood waters without damage. The document concludes by noting areas for improvement in ROS and calling for use of modern rainfall prediction techniques.

7.  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.
7
 Gate Operation
Schedule (GOS) is
the sequence in
which gates are
operated so that
required discharge
is released safely.

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

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

 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.
