Example figures: Duration of low water

Explanations

Period of time during which the water level lies below a given threshold.

• left top: result for threshold -1.875 m.
• right top: result for threshold -0.875 m.
• left bottom: result threshold 0.125 m.
• right bottom: result for threshold 1.125 m.

Examples

water levels below -1.875 m	water levels below -0.875 m

water levels below 0.125 m	water levels below 1.125 m
