OverFlood is a powerful software application
specifically developed for flood wave control
by automatic operation of the dam outlet
works.
Because of the high level calculations required
and for security reasons the software runs on a
dedicated PC connected on line to a server
where two other specific pieces of software –
OverDam and SQL DB – are located.
The OverFlood package is made of the three
following applications:
1. CCP – Flood Prediction Centre (or CCP 1st
phase)
2. CLP – Flood Control Centre (or CCP 2nd
phase)
3. FloodMan
1 CCP Software calculates the flood wave approaching the dam as a function of acquired
pluviometric data and interacts with a specifically developed mathematical model,
which takes into account essential parameters such as reservoir shape and soil characteristics. He control panel for the CCP process
is always activated (for configuration of
threshold, rain-meter and alarm parameters),

whereas interrogation of rain-stations takes
place at predetermined intervals (e.g. 1
hour). Whenever the rain-meter parameters
are exceeded, rainfall data enters the mathematical model, is processed, stored in the database and then displayed as a diagram,
flow versus time.

CLP software is always ready and active to
process the flood wave predicted by the
CCP. Depending on the type and shape of
outlet works, reliable predictions of controlled flood waves can be made. By generating alternative flood wave configurations
the software can predict the optimal settings
for the dam floodway works in order to offer
the engineer viable options for flood control.

3 FloodMan Software was developed as a
training tool to simulate a virtual flood wave
to be controlled by opening the outlet works.
This exercise for the dam engineer, being offline, does not take into account such vital
parameters as rainfalls, reservoir conditions,
outlet works, and the dam’s overall conditions. However it does provide excellent
practical instruction in flood control in a safe
environment.
