Field Application and Analysis to Levee Leakage Monitoring Method
Introduction

Study Period : Mar. 29, 2011 ~ Mar. 4, 2013

Research necessity :

- Recently, the world is faced with disaster due to global climate change, therefore, climate forecasting has be being more and more difficult

- Levee is important hydraulic structure due to protecting us from flood, and if this would be collapse, huge hazard will be occurred

- For these, continuous monitoring in levee is necessary in order to prevent from huge hazard

Levee Failure Hazard Increase the Hydro Disaster Levee Failure

Results of the study

In this project, we did develop the optical fiber sensor, which is economical and sensitive, and install this sensors to Yul-ji levee to observe the seepage, the displacement, and so on. We did successfully get many data such as soil temperature, pore water pressure, groundwater fluctuation from installed sensors in the levee. These monitoring data would be fully used for conducting the simulation and the observation in the mechanism of levee seepage. Besides, if we faced with huge flood event, we can easily know the timing of evacuation by using this monitoring system.
