TRIAL VISUALIZATION IN EMBANKMENT BREACHING PROCESS USING TRANSPARENT SOIL

Abstract

 Levee breaching occurs recently during floods in torrential rain and causes severe damages in landside area. For disaster mitigation, it is of great importance to understand the mechanism of flows and sediment transport in the breaching process and consider countermeasures. In this study, to obtain spatial distribution of saturation and examine the breaching process, hydraulic experiment of levee breaching due to overtopping flows is carried out, using transparent soil. Then, conducting image analysis, visualization of saturation in the embankment body is shown, which cannot be obtained in the case of sand.
