Basement v.3.2.0 - Vegetation

Hello everyone,

i am testing the vegetation's module implemented into the latest Basement release and i have any question about it.
 
  > into the "System_Manual_v3-2-0.pdf", page 185, it is specify that "vegetation should be used in combination with a “MPM_like” formula
     for bedload transport..." but into the tutorial file model.json of "Alpine_Rhine_vegetation_tutorial" it is selected only "MPM", which one is
     correct?

  > into the "System_Manual_v3-2-0.pdf", page 147, it is specify that "θcr,v (> θcr,g)" but the "theta_critical_value" used into MPM_like
     formula is 0.047 for bedload and the "veg_theta_critical_fact" is 0.02. So, what is the "veg_theta_critical_fact"?

  > when i set the Strickler value for a vegetation_region into hydraulics module i need to reduce it due to the presence of vegetation or
     should i consider the Strickler value for bare bad and set the correct value into "veg_strickler_fact" ?

Thanks in advance.
