Question velocity distribution in a channel

Hi,
I was modeling a flow field in a channel with groynes with a cfd program,
But velocity distribution is not similar with the experimental results.
My model has a very negative velocity between the groynes but the experiments show less negative velocity.
What can I do to solve this problem?
I think I must change the roughness around the groynes but I don't know increase it or decrease it because I don't know the mean of negative velocity!!!
Please help me.
Thanks
