Phosphorus mobilisation and transport within a long-restored floodplain wetland

► Phosphorus mobilisation following inundation of a restored floodplain is examined. ► In situ monitoring used within a floodplain that has been restored for over 20 years. ► Phosphorus release to surface water and porewater following sediment inundation. ► Magnitude of phosphorus release predicted based on sediment geochemistry. ► Hydrological pulses transport mobilised phosphorus into floodplain drainage network.
