New island in front of Langenargen: Start dredging work for lake drain!

Langenargen, Deutschland - A new island has formed in front of the Argen mouth, which has led to significant changes in the drainage of the ARGEN into Lake Constance. The port entrances of the BMK port in Langenargen and the port Ultramarin Kressbronn are now hardly navigable. The island, which was created in front of the landing, changed the direction of flow of the Argen to the west, which broke through a small headland that separated the argors and the port entrance at low water. Angela Mesmer, the port management in the BMK yachthafen Langenargen, said that the port facilities are related to the district offices and the regional council to clarify the situation.

From Monday, dredging work will begin to create a new gutter that is supposed to ensure the unhindered flow of water from the Argen into Lake Constance. This work was approved by the responsible authorities and is expected to continue until February. Such silencing is rare, since only a few rivers like the argene transport such quantities of beds.

The changed direction of flow has direct effects on the use of the lake. Ships with a larger depth can no longer drive in the port entrance. This has caused the water protection police to move their police boat out of the harbor because the water depth was no longer sufficient. In addition, those responsible for the Kressbronn Hafens Ultramarin have also observed sediment collections in their port entrance, although not to such a dramatic extent as in Langenargen.

The formation of islands is a fascinating geological phenomenon that is due to different processes. These include the elevation, which can occur through tectonic forces, volcanic activities or isostatic compensation processes. Such uplifting processes are crucial for the development of islands and their geological characteristics. Interdisciplinary approaches in geology, geophysics and oceanography help to better understand these mechanisms. In many cases, these uplifting processes also interact with erosion and volcanism, which influences the stability and expansion of islands.

island formation in the global context

A remarkable example of this geological process is the Canary Islands that have arisen from Hotspot volcanism. The creation of this volcanic archipelago in the Atlantic Ocean impressively shows how lifting events, how to climb hot materials from the ground mantle, can lead to the creation of new land masses. This type of volcanism can take place in several stages, which range from Underwater Vulcanic Activities to erosion and sedimentation.

The Canary Islands also illustrate the role of erosion and marine processes that form the coastal landscape. Volcanic activities not only produce new land masses, they also create a variety of rocks that contribute to the fertility of the soils. In the example of the Canary Islands, volcanic eruptions took place about 20 million years ago during the Miocene, which led to the impressive geological structures and landscapes that we can see today.
