Tag:waterway=security_lock

A security lock (also known as flood barrier, surge barrier or storm surge barrier) is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier.

It can also be an automatically controlled safety gate. This is a structure for safely closing a shipping canal in the area of a dam section or a canal bridge, i.e. sections where the water level is above the surrounding terrain.

This feature is not intended for mapping lock inspection locks that are closed manually (with a crane) during maintenance/repair of a lock.

How to map

• Draw a line for the security lock and add waterway=security_lock.
