Lastflusses
Lastflusses refers to residual, post-flood flow pathways that persist in a river basin after major discharge events. These channels may remain wetted when the broader river network has contracted, creating a mosaic of surface and shallow subsurface routes that convey water and sediment at low discharge levels for extended periods. Their existence reflects the dynamic reorganization of river networks following floods.
The term was coined by researchers studying flood-memory and channel reorganization in temperate floodplains in the
Formation and characteristics: Lastflusses form as sediment is redistributed, banks adjust, and connections to aquifers are
Impacts and uses: Lastflusses affect groundwater recharge, nutrient transport, and habitat connectivity for aquatic and semi-aquatic
Distribution and study: Documented in several temperate basins worldwide with variability tied to geology, soil permeability,
