C | The depths of the bottom of the model is specified in |

C | terms of an XY map with one depth for each column of |
| 20 |
|
|
C | grid cells. Depths do not have to coincide with the |
| 21 |
|
|
C | model levels. The model lopping algorithm makes it |
| 22 |
|
|
C | possible to represent arbitrary depths. |
| 23 |
|
|
C | The mode depths map also influences the models topology |
| 24 |
|
|
C | By default the model domain wraps around in X and Y. |
| 25 |

C | This default doubly periodic topology is "supressed" |
