Runoff estimation can be done by Rational Method and empirical formulae like Lacy's Method, Khosla's Method etc. and also with the help of modern softwares like HEC-HMS, Storm Water Management Model (SWMM). Widely used method for runoff estimation and drainage modelling is SWMM; using SWMM ...

However, this statistical method for designing runoff control is different from IDF sampling method applied for Rational Method. Therefore, the goals of this study are: (1) to move towards RM 2.0 by developing a new method that takes into account runoff control effects at the catchment scale, ...
SOME OBSERVATIONS ON THE RATIONAL METHOD FOR PEAK FLOW PREDICTION ON FLAT RURAL WATERSHEDS IN QUEBEC However, the applicability of the rational method to this region has never been previously tested. Rainfall and runoff measurements from a small, flat rural watershed in western Quebec were therefore...
Method The Rational equation is the simplest method to determine peak discharge from drainage basin runoff. It is not as sophisticated as theSCS TR-55 method, but is the most common method used for sizing sewer systems. Rational Equation: Q=ciA ...

WMS:Rational Method WMS includes an interface to the rational method which can be used for computing peak flows on small urban and rural watersheds. The interface includes the capability to combine runoff from multiple basins. Two different methods for determining peak flows/hydrographs at downstream...
WMS:Rational Method Outlet Data跳到导航跳到搜索 Some of the information for outlet points is automatically determined from the contributing area upstream, while other parameters are entered separately. The area is determined by summing the area of all upstream sub-basins. The runoff coefficient is...
This paper first examines the similarities and differences between the probabilistic rational method (PRM) (the currently recommended method for Victoria and eastern NSW in Australian Rainfall and Runoff) and the generalised least squares (GLS) based quantile regression technique (QRT). It then uses ...
