Abstract

In this research a suspended solid transport experiment was conducted in the river experiment center to find the characteristics and dispersion of the material. Modeling by the particle dispersion model was also executed to reproduce the suspended solid transport. The suspended solid was consisted of a mixture of silica and water using a mixing equipment, which was then introduced into a real-scale flume and measured with the laser-diffraction based particle size analyzer(LISST) to find the concentration of the material. The comparison between the measured suspended solid concentration using drone images and particle size analyzers, with the model showed a good match overall, which proved the applicability of the model. Along with finding the model applicability, the research showed the potential for suspended solid estimation in high flow situations with high rainfall.

본 연구에서는 하천실험센터에서 부유 물질 실험을 수행하여 부유 물질의 거동 및 확산을 관찰하고 이를 입자분산모형을 통하여 그 이동을 구현하고자 하였다. 규사를 물과 믹서기를 이용하여 혼합한 후 실규모 크기의 실험수로에 인위적으로 투입하고 레이저부유사측정기(LISST)를 이용하여 부유 물질의 농도를 측정하였다. 실험에서 드론 이미지 및 부유사 측정기 관측 데이터와 입자 분산 모형을 통해 부유 물질의 거동을 모의하여 비교한 결과, 비교적 실험 결과가 구현이 잘 된 것을 확인할 수 있었다. 이를 통하여 입자 분산 모형의 적용성은 물론, 높은 강우량으로 인한 유량 발생 시 부유 물질 예측 활용성을 기대할 수 있게 되었다.
