SEDIMENT MOVEMENT OBSERVATION SYSTEM
To provide a sediment movement observation system having such a structure as to prevent erroneous detection and erroneous notification.SOLUTION: There is provided a sediment movement observation system 1 for observing inflow or approach of sediment to a preservation object. The system includes a movable body 4 embedded inside the sediment of an observation object 3, a transmitter which can transmit a low frequency electromagnetic field signal incorporated in the movable body, and a receiver which detects the low frequency electromagnetic field signal transmitted from the transmitter. The size of the movable body is set to be transported while floating when the sediment of the observation object flows down.SELECTED DRAWING: Figure 4
【課題】誤検知や誤報知の起き難い構成の土砂移動観測システムを提供する。【解決手段】保全対象物への土砂の流入又は接近を観測するための土砂移動観測システム１である。そして、観測対象３となる土砂の内部に埋設された移動体４と、移動体に内蔵された低周波電磁界信号の発信が可能な発信装置と、発信装置から発信された低周波電磁界信号を検知する受信装置とを備えている。ここで、移動体の大きさは、観測対象となる土砂の流下が生じた際に浮上して輸送されるように設定されている。【選択図】図４
