The Rational Formula Interpreted Using a Physically-Based Mathematical Model
Rational Formula Physically-Based Mathematical Model
2009/10/27
A new interpretation is given for the rational formula in view of a mathematical model founded on the kinematic overland flow and Green and Ampt infiltration equations. The potential variability of th...
An Improved Rational Method for Urban Runoff Application
Improved Rational Method Urban Runoff Application
2009/10/26
In the initial stages of drainage systems planning and for independent tests of
advanced runoff model performance there is a need for a simple point flow
model. In these cases a method is proposed w...

Rational Method Design Complex Urban Basins
2009/10/23
Because of its simplicity the rational method is still frequently used in urban
planning and design. In this paper using the time-area method and statistically
derived design storms, the design peak...
Towards a rational definition of potential evaporation
