C *==========================================================* |

C | SUBROUTINE INI_DEPTHS |
| 14 |
C | o define R_position of Lower and Surface Boundaries |
| 15 |
C *==========================================================* |
| 16 |
C |atmosphere orography: |
| 17 |
C | define either in term of P_topo or converted from Z_topo |
| 18 |
C |ocean bathymetry: |
| 19 |
C | The depths of the bottom of the model is specified in |
| 20 |
C | terms of an XY map with one depth for each column of |
| 21 |
C | grid cells. Depths do not have to coincide with the |
| 22 |
C | model levels. The model lopping algorithm makes it |
| 23 |
C | possible to represent arbitrary depths. |
| 24 |
C | The mode depths map also influences the models topology |
| 25 |
C | By default the model domain wraps around in X and Y. |
| 26 |
C | This default doubly periodic topology is "supressed" |
| 27 |
C | if a depth map is defined which closes off all wrap |
| 28 |
C | around flow. |
