The productive embankments on the watercourse bottomland disturb the water-sediment lateral exchange between bottomland and main flume,which have great influence on the riverbed evolution.

Analyzes the effect of linking pipe velocity head and the momentum exchange between flow to and from the surge tank and that in the draft tunnel on the stable sectional area of the downstream surge tank with linking pipe by using the head loss coefficient obtained from Gardel s empirical equations for T-junction flow.

This paper analyses the factors influencing on the intensity of turbulent flow with suspended particles and establishes a turbulent intensity model of suspended particle flow based on the theory of momentum exchange.

Using the new method the contributions of the azimuthal correlations of particles distribution and the correlations of transverse momentum magnitude of final state particles to high order collective flow correlations are analyz.

A new simulative method of phenomenological collective flow events is proposed, which involves both the azimuthal correlations of distribution and the correlations of transverse momentum magnitude of particles.

1A GeV Ne+NaF collisions at the Bevalac streamer chambe,the transverse motion correlations arising from collective flow are studied include azimuthal correlations and correlations of transverse momentum magnitude.
