Hi,

I've tried to make a 2D hydrodynamic model with Fortran 77.

I used rectilinier finite difference Arakawa C-grid on it and Richardson Mesh.

The grid was simply illustrated like this...:

Code:
       +-----V(1,2)----+-----V(2,2)-----+
       |               |                |
       |               |                |
       |               |                |
    U(1,2)  Z(1,2)  U(2,2)  Z(2,2)  *U(3,2)
       |               |                |
       |               |                |
       |               |                |
       +-----V(1,1)----+-----V(2,1)-----+
       |               |                |
       |               |                |
       |               |                |
     U(1,1)  Z(1,1)  U(2,1)  Z(2,1)    *U(3,1)
       |               |                |
       |               |                |
       |               |                |
       +----*V(1,0)----+----*V(2,0)-----+
*  Not Used


I've used the model for simulate the region on shallow water. I've used Tide and Wind to generate the circulation.

Recently, i got the project on an Estuary... Of course there was discharge from the river that also generate the circulation.

I never got the situation like this and never learn from college.

So, could you anyone help me with the situation. What parameter that has to be changed on the filling the grid with Discharge from River?? I've heard that water Elevation must be changed?? Particularly on Continuity Equation must be changed also??

Thank You
Mujahid

Anyone else have this thread stuck as looking read with nothing to see? Now there's something to see.

Hmm, so this is for homework or something? Not ROMS at all? In ROMS, you would specify flux through one or more of the u,v points, which would change the elevation of the grids on either side (if there is water on both sides). This happens through the elevation equation for the center of the grid responding to net flux into the box. A "river" is usually flux through a wall separating land from water.
