도로 노면의 형상과 강우의 임계 지속시간을 고려한 적정 우수 유출량 산정 및 영향분석 = The Effects of Road Surface Geometry and Critical Rainfall Duration on Storm Runoff

다국어 초록 (Multilingual Abstract)

When calculating the storm runoff from road surface, it is recommendable to introduce the critical duration of rainfall by means of the RUNOFF(SWMM) model,or the Rational method with the travel time values of the kinematic wave` or Kerby`s equation modified by multiplying the correction factor of 2.3 or 1.1, respectively. But the travel time of 5∼10 minutes suggested in the Guide Manual for Sewer Design is too long to use for calculating road surface runoff. The peak runoff rate increases as the road sectional slope increases, whereas it shows the opposite results for an increase in the longitudinal slope. Also, the effects of the width and length of the road on the surface runoff rates increases greatly, as their values increase.
