Two Types of sediment

Hello, I'd want to simulate two different types of non-cohesive sediments (different sediment sizes) using different transport formulas. Is it possible to use a transport formula for each sediment type?

Yes, it is possible. E.g. of sed-file input:

1
[Sediment]
2
   Name             = #Sediment1#                   Name of sediment fraction
3
   SedTyp           = bedload                       Must be "sand", "mud" or "bedload"
4
   IniSedThick      =  1.0000000e+000      [m]      Initial sediment layer thickness at bed (overuled if IniComp is prescribed)
5
   RhoSol           =  2.6500000e+003      [kg/m3]  Specific density
6
   TraFrm           = 1                            Integer selecting the transport formula
7
   CDryB            =  1.5900000e+003      [kg/m3]  Dry bed density
8
   SedDia           =  1.4142136e-03      [m]      sediment diameter (D50)
9
   ACal             = 1                                Calibration coefficient                
10
   RouKs            =  0.000 
11
   SusFac           = 0.000    
12
[Sediment]
13
   Name             = #Sediment9#                   Name of sediment fraction
14
   SedTyp           = bedload                       Must be "sand", "mud" or "bedload"
15
   IniSedThick      =  1.0000000e+000      [m]      Initial sediment layer thickness at bed (overuled if IniComp is prescribed)
16
   RhoSol           =  2.6500000e+003      [kg/m3]  Specific density
17
   TraFrm           = 4                            Integer selecting the transport formula
18
   CDryB            =  1.5900000e+003      [kg/m3]  Dry bed density
19
   SedDia           =  2.3664319e-03      [m]      sediment diameter (D50)
20
   ACal                  = 8                                Calibration coefficient                
21
   PowerB                = 0.000000                                Power b                                
22
   PowerC                = 1.500000                                Power c                                
23
   RipFac                = 1.000000                                Ripple factor or efficiency factor     
24
   ThetaC                = 0.025000                                Critical mobility factor
