Unrealistic velocity pattern

Hello Everyone,

I am trying to simulate flow over a model hill according to a paper. My velocities are good with the paper, however, when I check my pattern, I dont find it realistic. It is also same for turbulent kinetic energy. Could you also comment about it ?
Boundaries:
Top = Inlet, (U,k,epsion abl)
Inlet = Log velocity profile
Bottom = Wall
Outlet = Pressure outlet
K-epsilon solver, standart wall functions, y+ is in valid interval.
