Abstract
Recently, there have been a lot of numerical models for prediction of urban inundation damage due to the climate change and heavy rainfall by using the combined drainage system. However, it is very difficult to estimate how much of discharge on the ground surface is drained hrough storm drains. Also,discharge coefficient of each formula is different depending on research groups. Hence in this study,laboratory scale experiments which can be fundamental experiments to measure the inlet discharge coefficients of weir and orifice into the storm drain are carried out and they could be divided into submerged and non-submerged cases. From the comparison between experimental and simulation data,each coefficients show good agreement in all the cases of steady state.
