low velocities in coastal lagoon

[flcastej]

Hi,

I am using ROMS in a shallow coastal lagoon, and forcing it with real wind data from a meteorological station near the place where a current meter was deployed.

I am getting low velocities in the E-W axis, comparing the model result with the current data registered. In the N-S axis it works ok. Someone could help me? or give me any sugestion about it. I have atached a file showing the coast and the model node nearest. to the position of the currentmeter.

I am using 10 sigma layers, and the node size is 40m. The grid orientation is N-S.
The parameter values are:


THETA_S, THETA_B, Hc (m)
4 1.0d0 1.0d0
rho0:
1030.d0
lateral_visc: VISC2, VISC4 [m^2/sec for all]
0.0242 0
tracer_diff2: TNU2(1:NT) [m^2/sec for all]
30*0.d0
vertical_mixing: Akv_bak, Akt_bak [m^2/sec]
1.0d-6 1.0d-5
bottom_drag: RDRG [m/s], RDRG2, Zob [m], Cdb_min, Cdb_max
0 0 0.001 1.d-4 1.d-1
sponge: X_SPONGE [m], V_SPONGE [m^2/sec]
60 0
gamma2:
1.d0
nudg_cof: TauT_in, TauT_out, TauM_in, TauM_out [days for all]
1. 360. 1. 360.
