Rhine Flood Peak Predictions and Impact on Navigation and Flood Measures
Expectations suggest that the Rhine's winter floods peaked over the weekend. As per forecasts, the water levels in North Rhine-Westphalia should start declining from Sunday. Surprisingly, Cologne's water level stood at 7.37 meters above flood level I of 6.20 meters as of Saturday afternoon. At flood level I, vessels are limited to a maximum speed of 20 kilometers per hour.
Interestingly, Cologne reached its first high water mark for shipping of 6.20 meters on Tuesday morning. However, the current water levels across the country still fall short of a navigation ban due to high water mark II. In Düsseldorf, high water mark I of 7.10 meters might be reached by Sunday, followed by a falling water level. As of midday Saturday, the water level in Düsseldorf was 6.93 meters.
Weather forecasts and water level predictions are vital for cities along the Rhine, including Cologne, Bonn, Emmerich, and Duisburg. Authorities in Cologne, specifically, are making active efforts to implement flood measures.

Predicted peak levels of winter Rhine floods primarily rely on forecasts that emphasize the impact of climate change on precipitation and snowmelt. For instance, the Zhabay River Basin under climate change denotates that river discharge is projected to increase, necessitating long-term water resource management planning. Rhine River's specific trends are not detailed, but climate change is expected to intensify flood events.
For effective navigation and flood management, accurate weather and water level forecasts are indispensable. Early warning systems like the Extreme Forecast Index (EFI) and the Shift of Tails (SOT) have proven their worth, providing accurate warnings several days ahead.
Cities along the Rhine need to continuously monitor and prepare for potential flooding scenarios. Budapest, Hungary, and Serbia have implemented flood defense measures executed over multiple kilometers like the Danube embankment and the hydroelectric power system structures to minimize flood risks in the region.
