| Attribute name | Unit | Description | Default behavior (when attribute is missing) |
|---|---|---|---|
| WATER_DEPTH | m + datum | The maximum water depth across the polygon. | First, the average surface elevation of the polygon is determined. Then, the maximum depth of the water is set equal to the WATER_DEPTH_M attribute of the used water terrain type. |
| ANGLE OF REPOSE | ° (degrees) | The angle, relative to a horizontal plane, at which the water should be "carved" into the terrain. If the sides do not meet before the WATER_DEPTH is reached, the remainder of the bottom of the waterway will be flat. | The default angle is 90°, so the carving will run vertically downward until the WATER_DEPTH is reached. |
