10     C |==========================================================|
11     C | The depths of the bottom of the model is specified in |
12     C | terms of an XY map with one depth for each column of |
13     C | grid cells. Depths do not have to coincide with the |
14     C | model levels. The model lopping algorithm makes it |
15     C | possible to represent arbitrary depths. |
16     C | The mode depths map also influences the models topology |
17     C | By default the model domain wraps around in X and Y. |
18     C | This default doubly periodic topology is "supressed" |
19     C | if a depth map is defined which closes off all wrap |
20     C | around flow. |
