Yes, I agree with you @Subin. But angle should be between 60-75 degree.

All the above.
Attracting groynes point downstream, serving to attract the stream flow toward themselves and not repel the flow toward the opposite bank. They tend to maintain deep current close to the bank.
Deflecting groynes change the direction of flow without repelling it. They are generally short and used for limited, local protection.
Repelling groynes point upstream; they force the flow away from themselves. A single groyne may have one section, for example, attracting, and another section deflecting.
