Extracts the Manning velocity calculation into a dedicated, reusable function

to improve modularity.

Introduces the option to specify the Manning friction coefficient 'n' or
the Strickler coefficient 'M' (M = 1/n), providing more flexibility for
model configuration.

Simplifies the channel bed slope definition by replacing separate inlet and
outlet bed elevations with a single total elevation difference 'H'.
