The study of bioturbation effects by burrowing animals on seepage from a river embankment
River embankments are subjected to bioturbation by river burrowing animals,which destabilizes the embankment during flood transit,potentially leading to river embankment failure.To investigate the effects of burrowing animal bioturbation on seepage from river embankments,field investigations were conducted in the Renwen Trunk Canal channel in Hebei Province to assess the density and geometry of internal burrows excavated by burrowing animals such as river crabs and crayfish.Based on the field observations and indoor experiments,three-dimensional numerical simulations of the seepage process inside the embankment were carried out.The results showed that the burrows significantly shortened the relative damage time of the embankment under the hydraulic gradient during the high water level of the river during the abundant water period.
