Abstract
Recently, natural disasters, which are hard to predict and prevent, are rapidly increasing due to climate change worldwide. Particularly the damage scale of urban areas is increasing because of local torrential rainfall. In urban areas, the rain water cannot flow to pipes well due to the high percentage of impervious areas by the indiscriminate development. As a result, the inundation damage is getting higher in urban areas. So we need to characterize the interception of the grate inlets to ensure good drainage in impervious areas. But Korean installation criteria of grate inlets does not reflect road and drainage sector characteristics so the grate inlets do not function properly in many areas. In this study, we suggest the interception capacity equations about grate inlets through hydraulic experiments in various conditions. Therefore, the interception capacity changes are analyzed according to bearing bar slopes of grate inlets, grate inlet sizes and shapes and connecting pipe numbers. Though this, we developed the interception capacity equations about domestic grate inlets.
