Experimental study of density flow at the Yellow River Mouth

摘要

Physical model study was conducted on the density flow at the Yellow River mouth. Steady density flow occurs when sediment concentration reaches 5.0 kg/m~3. The hydraulic condition for the formation of density flow is in accordance with that in reservoirs. The density current moves at a higher speed and travels a longer distance as the concentration increases. Delta sand bar forms and advances due to sediment deposition. More than 30% of the incoming sediment was transported out of the measurement section with the help of density current.
