A computer glitch caused floodgates to open in Amsterdam during a storm, causing the water level in the canals to rise dramatically. Only thanks to the intervention of technicians, the city was saved from a severe flood.
Like many Dutch cities, Amsterdam is located below sea level, so protecting the city from water is an extremely important task. The water is controlled by a network of locks and canals. Any technical failure in this system can lead to disaster. Storm Ciaran, raging off the coast of North Holland, has caused water levels in the North Sea Channel to rise. Around 4 a.m., a computer glitch caused the locks to go into manual mode, allowing seawater to enter the city’s canal unchecked. In a few hours, the water level rose 32 cm above normal.
Fortunately, a technician from the local water management department noticed the abnormal water level and immediately informed his colleagues about it. Upon inspection, it was found that all 14 locks were open and seawater from the North Sea was moving uncontrollably towards Amsterdam. Thanks to the timely intervention of an engineer, the locks were manually closed and Amsterdam was saved from flooding.
Following this incident, it was decided to move the lock control post closer to the canal and install permanent monitoring and alarms to avoid similar incidents in the future. Automated systems can fail, and only timely human intervention can save from disaster.
