چکیده
Settling velocity is an important parameter affecting the characteristics of sediment transport. Especially for cohesive in estuarine or mangrove areas, determination settling extremely complex. The study focuses on anlalyzing relationship between and concentration. Based empirical formulas Hwang (1989) experimental data Mehta Li (2003), by concentration considered with variation four parameters a, b, m n. method applied to calculate Can Gio Biosphere Reserve, Ho Chi Minh city. From collected samples fieldwork, column test used determine velocities. With 38 velocity, semi-empirical curve determined. results show that free about 0.28 × 10-5 m/s; maximum 0.99 10-3 m/s corresponding 4.7 kg/m3. resulting values n are 0.05; 3.5; 3 3.2, respectively. reliable real applications.
