Some advanced equipments,such as River CAT,Mini Echo Sounder and Laser Particle Analyzer are used to measure the velocity field,water depth,and suspended sediment particle size distribution on eight typical cross-sections of continuous curves in Shapotou in the Yellow River.

Numerical simulation of bank discharge of the meandering channel by Finite Analytic Method;

The flow field and concentration of discharge both along bank and in the centerline of the meandering channel in laboratory are calculated, and the calculating .

The quasi two dimensional mathematical model of flow is used to simulate the movement of the rapid flow in the continuous bends with a total length of 6 km in the Taohe river which goes through Yangquan City.

A two-dimensional numerical model,which is in the curve coordinate,was applied to simulate the problem of warm water drainage in continuous bends.

In order to study the relations of section longitudinal gradient,ramp length on traffic accident rate in continuous downgrade road,traffic accident data and longitudinal parameters were collected from six continuous downgrade road sections.
