jäännösvetien
Jäännösvetien refers to relic or abandoned river channels in a landscape, where historical rivers have shifted course or ceased to flow on the surface. In geomorphology, they are remnants of former fluvial networks that persist as dry valleys, buried channels, or sediment-filled trenches. Jäännösvetien are important for reconstructing past hydrology, climate, and tectonic forcing, and can influence groundwater systems and land use patterns today.
Formation and morphology: They form when active rivers incise and abandon parts of their channels after changes
Detection and classification: Researchers identify jäännösvetien through geomorphological mapping, aerial photography, LiDAR, and geophysical surveys, complemented
Significance: Jäännösvetien provide records of past hydrological regimes and landscapes, aiding paleohydrology, archaeology, and groundwater resource
