problem in SSIIM

hi,
i am a SSIIM user.
i have a problem in SSIIM please help me.
for F 16 dataset roughness in meter must be entered or n (manning coefficient roughness)
my model has a fixed bed and without sediment.(the iron channel.)
thanks

F 16 is the roughness ks in meters. In W 1 the roughness is given as Strickler's number. When F 16 is given, W 1 will be overwritten and only used for the initialization of the water level.

dear valgrinda,
thanks a lot for your answer.
are you a professional SSIIM user?
i need help for modelling in this software.

hi
i think if i use bedrough file for the bed cells in my model in ssiim and also use f 16 and w 1 dataset,the roughness in f 16 will be used for wall roughness and strickler number in w1 will be used for initialization the water level.is it correct?
thanks
