| In this study, a realtime bridge scour monitoring system was installed and operated to measure the real scour depths in relatively hard and rocky bottom. And riverbed change at before and after flood was investigated by GPR(Ground Penetrating Radar) to check the rationality of measured values. As the result of this study, it was revealed the inaccuracy of equilibrium scour depth estimation through the bridge scout equations because most of the equations do not reflect the differences of geological characteristics, evaluated the real scour depths considering both bed and flow conditions. |
