Visualization and control of the flood protection system for underpasses in Istanbul, Turkey

December 3, 2013 | Bretislav Valek

Istanbul is the largest city in Turkey with a population of nearly 14 million. There are over 7.5 million cars registered in Istanbul, which results in many traffic jams. To overcome the traffic problems, 62 underpasses were built on Istanbul's major roads. The underpasses are mostly equipped with a system designed to automatically pump rainwater that leaks into the underpasses during rainy days.


In spring and fall, when Istanbul gets heavy rains, some of the underpasses get flooded. The reasons why the pumping systems fail are electricity problems, jammed pipes, broken pumps, etc. In situations when an underpass is flooded, it can be very dangerous for people in cars to go through it. All this is the result of the fact that there's no system for the remote control and monitoring of the underpasses.


To prevent such disasters from happening, the Istanbul Water Authority (ISKI) decided to install a remote control and alarm system to all critical underpasses and control them from one place via a dedicated automation system.
