| Summary: | Scour is the erosion of stream bed or bank material from bridge foundations due to flowing
of
water. Data
logging from sens
or and electronic communication
systems can mo
nitor scour in real
-
time to
ensu
re the integrity
of
bridge structure.
A number of parameters are associated with scour, thus different types of sensor are required
to measure the individual affecting factor. A simple capacitive type direct scour sensor system is proposed and
validated by
simulation. The result shows that any change of the river bed dielectric property is a direct
indication of scour. Due to simple capacitive structure of the sensor system
,
it is highly robust and easy to
implement. The system can easily
be
implement
ed
wit
h an existing bridge structure
. A
wireless telemetry
system
can be used to send the real
-
time data from the proposed sensor to a desktop computer at the monitoring lab
