The Rational Method equation is designed to compute peak flows. However, a hydrograph, based on the peak flow and basin (or outlet) time of concentration, can be computed using one of five different unit hydrographs. Furthermore, there are two different methods (traditional and route by summing) hydrographs can be computed at confluence points.
The Rational Method Hydrographs dialog is used to specify the dimensionless unit hydrograph method, and the way hydrographs at outlets are computed. Options include:
- Traditional method
- Route by summing
- Hydrographaph computation method
