Short summary
The paper proposes a dimensionless framework to investigate the impact of the rainfall event structure on the runoff peak. A set of analytical expressions are derived from a constant hyetograph to assess the maximum runoff peak for a given event structure irrespective of the specific catchment. A catchment application is discussed to point out the dimensionless procedure implications and to provide some numerical examples of the rainfall structures with respect to observed rainfall events.
