Zusammenfassung:PROBLEM TO BE SOLVED: To provide an underwater soil sedimentation state detecting sensor capable of saving the time and the manpower. SOLUTION: An optical fiber capable of measuring the temperature distribution is provided under water and the underwater soil sedimentation state is detected by the temperature distribution measured by the optical fiber. The temperature difference is generated by difference in the heat conduction between in the water and the soil so that the optical fiber is detected to be buried in the soil.
