In the eroding coast with strong wave,absent sand and bare rock,groyne or jetty and offshore submerged groin engineering are needed to support this nourishment against the waves in order to maintain the filled sand stability.

Test Research on Protection of Root Rocks of the Bank Using Iron Wire Net in the Lower Reaches of Yellow River;

Based on the basic assumptions of the shallow water equation and demands of research on engineering problems, in combination with the definition of momentum coefficient, a depth averaged mathematical model is developed theoretically for calculation of flow field over submerged dikes.

It also introduces that the method of dispersion consuming energy of twin submerged dikes is used to regulate the cell vortex flow and improve the navigation condition on Xiaomi shoal.

Structure design on pilot project of movable and unemergency submerged dam in Yellow River downstream

The deposits of mouth bar and lakeshore bar are found at the middle oil-bearing assemblage (Qingshankou and Yaojia formations) in southern and western depositional systems, Songliao basin, characterized by large thickness and wide extension.
