Simplified rational method

Webb31 juli 2006 · Craig and Rankl (1978) developed a Modified Rational Method, which is an extension of the Rational Method for rainfalls that lasts longer than the time of concentration. As a result, a trapezoidal hydrograph was produced. A trapezoidal hydrograph assumes homogenous watershed and equilibrium limbs as shown in Fig. 1 … WebbThe Rational Method is widely publicised as a simple and effective method for use in hydrological calculations. Published data exist that cover a wide range of applicability, and it appears as a published method in many guideline and regulatory documents.

WebbThis work is for examining a simplified equation based on the rational formula, which can easily decide storm-water detention volume in small urban catchments. The storm-water detention volume is determined by the inflow hydrograph flowing to detention basin and the outflow hydrograph discharged from the detention basin. The ratio of average … The Rational Method is traditionally a peak flow method used for storm sewer sizing. It predicts peak flows using the formula Q=CIA, where the intensity I is taken from an Intensity-Duration-Frequency (IDF) curve using the time of concentration of each drainage area. Bentley's StormCAD product uses this methodology … Visa mer The purpose of this technote is to clarify how the Modified Rational Method works, how it differs from the Rational Method (Used in Bentley StormCAD) and the differences in its implementation between Bentley PondPack and … Visa mer In CivilStorm, SewerGEMS, and SewerCAD, storm information and catchment input are the same as with the traditional Rational Method (StormCAD) - the user must enter an IDF … Visa mer What if this is an existing system where the pre/post conditions are the same, or what if I don't care about the predevelopment peak flow?
