Statistics

Statistics by country and year

Yearly summaries computed from the daily readings of every station: how many station-days were spent below the low-water level (LDC) or above the high-water level (HDC) — as a count and as a share of the station-days with thresholds. Useful for agriculture (irrigation seasons with low water) and navigation (days with restricted draught).

• Agriculture: station-days below LDC mark the low-water periods when irrigation intakes and water availability are under pressure.
• Navigation: days below LDC mean draught restrictions on that sector; days above HDC mean suspended traffic.
