Natural dam discovery system, natural dam discovery method, and program

摘要

PROBLEM TO BE SOLVED: To provide a system for quickly detecting the formation of a natural dam. SOLUTION: This is a natural dam discovery system 1 for predicting the occurrence of a natural dam, and acquires a predicted water level acquisition unit 12 for acquiring predicted water level data indicating a predicted water level of a river and a measured water level data indicating a water level of a river. A natural dam discovery system 1 including a measured water level acquisition unit 14 and an analysis unit 16 that predicts a natural dam by analyzing the difference between the predicted water level data and the measured water level data. The natural dam discovery system 1 determines that a natural dam has been formed, for example, when the difference between the predicted water level data and the measured water level data exceeds a predetermined threshold value.
