Through the physical modelling test of low-resistance upright plate, we studied the characteristics of resistance varying along longitudinal and transverse sections The result shows that the transverse section method has obvious advantages in deltecting the sliding fault.

Under these new conditions, new fluvial trends haveshown on the plain morphology、longitudinal section and cross section in thelower Yellow River.

Numerical simulation study on longitudinal profile of scouring funnel;

Analysis on longitudinal profile evolution of mid-reach of Huaihe River from Honghekou to Fushan

Based on the flume experiment of the clear water scouring at the sandy bed,the observation and analysis are carried out about the longitudinal profile adjustment,the scale of sand wave,the thickness of the bed materials armoring layer,the relationship between armoring bed materials layer and sand wave migration,the graduation of the bed materials armoring layer,bed load graduation etc.
