So for the Urban Flood Risk Mitigation model, the estimated runoff is calculated with the Curve Number method. Inside of this formula, the initial abstraction is defined as λ=0.2.
As far as I can tell, this number is probably based on the original SCS-CN method, and has, rightly so, been employed in many studies.
Now, more recent research comes to the conclusion that, also especially for urban environments, which this model is ultimately aiming for, the initial abstraction should be way smaller, around 0.05 as opposed to the original proposed 0.2 value (Woodward et al. (2003) Runoff Curve Number Method: Examination of the Initial Abstraction Ratio)
As the initial abstraction is not a user influenceable input value, I was wondering if there might be any plans for future versions where this more up to date initial abstraction value might be taken into consideration, or where the initial abstraction value might become a user influenceable value depending on local conditions (f.ex. proposed by Krajewski et al. (2020), Variability of the Initial Abstraction Ratio in an Urban and an Agroforested Catchment) in the user interface?
