| Abstract: | The laboratory calibration were used to determine the relationship between backscattered signal strength and sediment concentration.A non-intrusively way of concentration measurement was introduced, and the inner fluctuation of concentration was analyzed rudimentarily.Finally,according to the fluctuation concentration acquired by MicroADV,the equilibrium of upward flux and downward flux were compared quantificationaly. |
