In addition to various unit hydrograph transform methods and SWMM nonlinear reservoir runoff method, InfoWorks ICM also has a built-in rational routing model for rainfall-runoff process. To utilize the Modified…
HydroCAD and XPSWMM have the modified rational method built into the programs and it is very convenient to apply the method in either of the modeling tools. One or more…
For small drainage areas, the rational method is widely used to calculate peak flows of different drainage design levels to size storm sewer, inlets, culverts, and ditches. The rational method…
