Transverse distribution of flow velocity in compound channel and its effects on floodplains levees

3-D Micro acoustic Doppler velocity(ADV) was used to test the round jets in cross flow in unsymmetrical compound channel.

Generally, many natural rivers have compound channels, possessing a main channel, and one or two floodplains.

Experimental study of flow characteristics in compound cross section channel;

Aiming at this problem,application of compound cross section is put forward and the method that determines the optimal hydraulic condition of compound cross section by using computer program is concluded.

Hydraulic characteristics of water flow at “Y”-shaped junction of river channel with compound cross-section;

This paper presents an efficient numerical method by using preissmann implicit scheme to diseretize the De saint-venan equations,which is based on the characteristics of the rivers with compound cross-section.

This paper discusses the calculation error of traditional dividing section method in complex section channel by theoretical analysis,and produces a new dividing section method which the velocity of dividing section is equal.

Flow pattern of compound section river bend;

The predictions of the secondary currents in the asymmetric compound open-channels with different depth of the floodplain were carried out using the Launder & Ying algebraic stress model.
