Waterway Information least leveled depths (lines)

Least leveled Depth. Indication of the location of the ground plane relative to NAP or target level. For some waterways, a value of plus NAP may therefore be entered here. Due to the rapidly changing ground position of trenches in tide areas, the depth of these waterways recorded in Vin may differ from the current situation. This also applies to a number of rivers whose soil position changes almost continuously after a high water period. For the current depth data of these waterways, please contact the waterway managers. Notation: If there is a summer and winter level then the depth is always given up compared to the win at the level
