I must analize this situation for a river.
EHQ Full liquid [m3/s]: 9
Magnitude event [m3]: 820
Porosity material: 0.3
Actual magnitude (effettiva): 1200
Ks debris flow [m1/3 / s]: 12
Qmax debris flow [m3 / s]: 45
Hydrograph to be included
T (seconds - Q):
0 - 0.0
30 - 45.0
120 - 11.3
600 - 0.0

What Voellmy's coefficients should I put in the software to analyze this situation?
