Problems with surface elevations

[fanzhongya]

Hi everyone,

I’m trying to simulate tide currents in Yangtze River Estuary with ROMS. I only used harmonic constants without currents as open boundary forcing, which were calculated from a big domain model. My colleges have run the model well using these harmonic constants with FVCOM and DELDT3D. However, surface elevations were overestimated in my model (Zob = 0.0003) (see Figure 1 ).

The open boundary options I used were shown below:

/*Open boundary options using only harmnic constant from sklec*/
#define RAMP_TIDES

#define SSH_TIDES

#define EAST_FSCHAPMAN
#define SOUTH_FSCHAPMAN
#define NORTH_FSCHAPMAN
#define EAST_FSOBC
#define SOUTH_FSOBC
#define NORTH_FSOBC

#define EAST_M2REDUCED
#define SOUTH_M2REDUCED
#define NORTH_M2REDUCED

#define FSOBC_REDUCED
#define ANA_FSOBC
#define ANA_M2OBC

Any suggestion is appreciated!
