  • Figure  1.  Area of study. Red circles indicate the deploy location of the ADCPs, and the dashed blue line represents Xuliujing Section.

    Figure  2.  Time series of the discharges at Datong station (thumbnail image in Fig. 1) in 2011. Datong is the last permanent hydrometric station with long discharge records on the main Changjiang River, and the discharge is difficult to observe owing to the tidal influence. So the discharge in Datong is commonly regarded as the net discharge into the East China Sea.

    Figure  3.  Shapes of Xuliujing section on three different dates of 2011. A boat-mounted single-beam echo sounder transducer (sonar) was used for bathymetric surveying at Xuliujing Section (Fig. 1) once a month. The echo sounder was a 208 kHz HY1600, 8 degree transducer, with a depth accuracy of 0.01 m+0.1%D (D is measured depth) and sampling rate of 5 Hz.

    Figure  4.  Energy partition of vertical-averaged currents at three ADCP stations. Area of pie chart (top-row) indicates total kinetic energy variance σ2KEdat, and the sector is the Kinetic energy variance ratio VE, which represent s relative contribution of the tidal component to the total flow in each season. The largest pie appears at C2 station in summer and it representing 0.67 m4/s4. Histogram bars indicate percent energy En in the individual constituents.

    Figure  5.  Vertical profiles of mean current for the three ADCP stations. Direction is counterclockwise angle from east.

    Figure  6.  M2 tidal constituent ellipses at different depths. Blue lines indicate measured data, red lines are solution of optimally fit frictional model with a constant eddy viscosity and corresponding value of cost function (detailed in Section 4.1).

    Figure  7.  Barotropic current (red line) and vertical distribution of baroclinic current (blue line) for M2 constituent at different stations.

    Figure  8.  The vertical distribution of M2 ellipse parameters and the frictional model for three stations. Dots indicate measured data, solid lines are optimally fit model solution with a constant eddy viscosity and corresponding value of cost function (detailed in Section 4.1). Horizontal lines denote the tidal-averaged water depth.

    Figure  9.  Frictional model solutions using four different eddy viscosity ω appropriate to the Station C2 in spring. Dashed line indicated ω=2×10−4 m2/s, dots line indicate ω=5×10−4 m2/s, solid line indicated ω=10×10−4 m2/s and thick solid line indicated ω=20×10−4 m2/s.

    Figure  10.  Seasonal variation of mean currents at upper, middle and lower layers (0.2D, 0.5D and 0.8D, D is water depth) for three ADCP stations.

    Figure  11.  Seasonal variation of M2 ellipses at upper, middle and lower layers (0.2D, 0.5D and 0.8D, D is water depth) for three ADCP stations.

    A1.  Tidal current ellipse can be thought as the combination of two circles.
