Meuse

The Meuse, also known as the Maas, is a major European river.

It serves as a vital waterway through several different countries. The river rises in France on the Langres plateau. From there, it flows north through Belgium and the Netherlands. Finally, it drains into the North Sea. It is part of a massive system called the Rhine–Meuse–Scheldt delta.

This delta is where the river meets the sea along with other large rivers.

The river's path is shaped by many different landscapes and tributaries. It begins in the commune of Le Châtelet-sur-Meuse. It flows past Sedan, which marks the head of navigation. After passing Charleville-Mézières, it enters Belgium. At Namur, the Sambre river joins the Meuse.

The river then winds east past Liège.

In the Netherlands, the river flows through Venlo and Maastricht.

The river is joined by many smaller rivers, such as the Ourthe and the Semois.

Human engineering has significantly changed the river's course over time. During the late Middle Ages, a major flood changed its path. This flood connected the Meuse to the Merwede at Woudrichem. This event created the Afgedamde Maas, which became the main branch. Eventually, the original branch silted up and became the Oude Maasje. In the late 19th and early 20th centuries, engineers separated the Rhine and the Meuse. They created a new, artificial mouth called the Bergse Maas.

This separation reduced the risk of flooding. It is considered a massive achievement in Dutch hydraulic engineering.

In 1904, a dam was completed at the southern inlet of the Afgedamde Maas. This meant that the Afgedamde Maas no longer receives water from the main Meuse. The river is highly important for transportation and industry. It connects major port areas like Rotterdam, Amsterdam, and Antwerp.

Large barges use the river to move goods through Belgium and the Netherlands. However, some sections are not navigable for all vessels. For example, the Juliana Canal is used to bypass an unnavigable section between Maastricht and Maasbracht. In France, the river is canalized over a specific distance.

The Meuse has played a central role in many historical events. The river and its crossings were key objectives during the Battle of France. They were also important during the Battle of Sedan. In World War II, the river was involved in the Battle of the Bulge. This was the last major German counter-offensive on the Western Front. The river has also been a political boundary. Since 1301, the upper Meuse roughly marked the border between the Holy Roman Empire and France. This boundary remained relatively stable for many years.

There are many surprising facts connected to the river's name and history. The name Meuse comes from the Latin name Mosa. This likely comes from a Celtic name, *Mosā. This root may be related to the English word "maze," describing the river's twists. Interestingly, a famous sea reptile was named after this river. The Mosasaurus was named for the Meuse.

Scientists discovered the first fossils of this creature near Maastricht in 1780. The river has also inspired art. The landscape of the Mosan valley inspired the painter Joachim Patinir during the Renaissance.

Managing the river requires cooperation between many different nations. The Meuse basin covers approximately 36,000 square kilometers. This area is shared by France, Germany, Luxembourg, the Netherlands, Belgium, and the Brussels region. In 2002, these countries signed an international agreement in Ghent. They formed the International Commission on the Meuse to manage the river. Each country contributes to the costs based on how much of its territory is in the basin. For example, Wallonia and the Netherlands each contribute 30% of the costs. This teamwork helps manage the river and protect against floods, like the catastrophic flooding seen in July 2021.
