FlussoxbowLake

FlussoxbowLake is a hydrological term used to describe a class of oxbow lakes formed within river floodplains by the cutoff of meanders in flowing water systems. The name combines elements referring to river flow with the oxbow concept, and the term is encountered in regional geomorphology studies and in some hydrological glossaries.

Formation occurs when a river during high-flow periods creates a shorter route by breaching the neck of a meander. The main channel abandons the old bend, and sediment deposition along the abandoned neck gradually isolates the cutoff bend from the active channel. Over time, water becomes stagnant or slow-moving, forming a crescent-shaped lake that may evolve into a marsh or wetland. In some cases, FlussoxbowLakes remain connected to the river through a temporary channel that floods seasonally.

Morphology and ecology commonly describe FlussoxbowLakes as having crescent or U-shaped outlines, shallow depths, and variable water levels tied to seasonal discharge. They support wetland vegetation and provide habitat for waterfowl, amphibians, and aquatic plants. Nutrient-rich runoff can lead to eutrophic conditions and algal blooms in warm seasons, influencing productivity and species composition.

Distribution and significance: the concept applies to meandering rivers in temperate to tropical floodplains and is used to discuss river dynamics, sedimentation patterns, and wetland restoration planning. While the term FlussoxbowLake is not universally standardized, it serves as a descriptive label for oxbow lakes that originate and persist within active floodplain environments shaped by recurring fluvial reworking.
