A new wave of extreme heat is hitting the heart of the European continent, and the consequences go far beyond the records in thermometers or the fact to see raised tram tracks. The Rhine River, Western Europe’s most important river highway, is seeing its water levels plummet and the result is that a logistical bottleneck is being generated that threatens the supply of fuel and fundamental raw materials for Europe.
The worry. The alarm has begun to be raised when it has been detected that the barges that navigate the river can barely carry half of their capacity, putting the supply of an important part of Europe in check. And all because of these heat waves that we are experiencing in Europe.
To understand the magnitude of the problem, you have to look at how inland navigation works, since the Rhine is not limited to water crossing Germany, France, Switzerland and the Netherlands, but is an industrial artery. Literally, coal for thermal power plants, chemicals for industrial giants, oil or automotive components are transported through this river.
The drought. When the flow of the river begins to decrease, its depth also decreases, and this collides with vessels that have a critical threshold. This means that if the water drops below a certain level at key points such as the famous Kaub bottleneck in Germany, captains are forced to drastically reduce their load to avoid running aground on the river bottom.
This makes load 50 or even 30% of the boat’s capacity It is not an exaggeration, but a physical necessity. This triggers a domino effect that means that, if a ship carries half the load, it takes a second to do the same work. And since there are no infinite ships, transportation prices skyrocket and goods either do not arrive on time or become very expensive.
It’s not just the Rhine. Although the exact impact figures should always be taken with caution because they vary greatly depending on the stretch of the river and the type of vessel, the general diagnosis is incontestable. Here the Joint Research Center of the European Commission has studied in-depth how limitations due to low water levels impact European rivers.
Its scientific framework perfectly explains the current collapse, since low levels not only reduce cargo capacity, but completely alter continental logistics flows, drastically increasing operating costs.
The reasons. Here the different institutions are clear that the problem lies in the lack of rain in spring and the lower amount of snow accumulated in the Alps during the winter, which causes the river to lose its natural “reserve” for the summer.
But also, the Rhine is clearly warming. This not only has clear economic effects, but also serious ecological impacts on the river’s fauna, which in turn forces additional restrictions to be imposed.
The new normal. What we are seeing this year does not seem like an event that remains a simple anecdote to tell our grandchildren, but rather the different evidence indicates that seeing low flow will be increasingly frequent due to climate change.
The proposed solution involves the use of AI to predict exactly when we will see these very low flows to optimize the supply chain, or simply build flat-bottomed boats with better drafts to be able to continue transporting cargo when the river is at even lower levels of flow.
