In cold snowy regions, there are frequent heating oil spill incidents in winter. In addition, oil spill under river-ice cover and its process can hardly be observed. In this study, a series of hydraulic experiments using ice model is performed to investigate oil spill phenomena under ice cover. As the result, it is clarified that spilling speeds become slower and the oil layer becomes thicker compared with the cases with open channel. Moreover, simulation by one dimensional two-layer unsteady flow model is performed and consequently it is revealed that oil spill speed is reproducible with appropriate shear stress at the interface and upstream end conditions.}, pages = {I_1597--I_1602}, title = {結氷河川の油流出時における油流下速度の予測手法に関する研究}, volume = {70}, year = {2014} }
