Alster Meander Bends

A beautiful river course in the middle of nature, just as the river wanted it. Rarely beautiful.

A nice section of the trail. At one point you are very close to the meandering Alster, the meandering arches. Over the years (centuries), the meandering river itself will develop into an oxbow lake. A meander hlas is broken and the river course is then shortened, thus straightening itself.

Meander is the designation of a river meander in a sequence of other river meanders, as it forms naturally in unpaved river sections with a very low bed gradient and at the same time transported, fine-grained bed load. Corresponding river sections are called meandering rivers.
Over time, meanders continue to spread laterally due to erosion on the outside of the curve (impact slope) and sedimentation on the inside of the curve (slip slope) until a breakthrough occurs at the ends of the loop.
After that, the meander becomes an oxbow lake and finally silts up.
The intensity of the meandering of a river depends on the nature of the subsoil and the flow rate.
The ratio of the length of the body of water to the linear distance, known as sinuosity, serves as a simple measure.(Source: Wikipedia)
