Abstract
A specifying system according to the present disclosure includes an optical fiber (30) laid along a levee (20) of a river (10), a communication unit (41) configured to receive, from the optical fiber (30), an optical signal containing a pattern that changes according to a state of the levee (20), and a specifying unit (51) configured to specify a water level of the river (10) based on the pattern that changes according to the state of the levee (20).
Claims12
A specifying system comprising:
- an optical fiber laid along a levee of a river;
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- receive, from the optical fiber, an optical signal containing a pattern that changes according to a state of the levee;
- specify a water level of the river based on the pattern;
- and
- specify the water level of the river based on a pattern that changes according to a vibration state or a temperature state of the levee, contained in the optical signal.
