Item type:Publication, Access status: with files , Bank erosion in alluvial rivers with non-cohesive soil in unsteady flowSo far the theory of bank failure in non-cohesive soils is limited to the avalanche of loose, not compacted, fully saturated discrete grains, applicable mainly to gravel banks. However, the present field investigation indicated that undercutting of the riverbank, slip failure of the submerged zone of the bank, as well as cantilever failure of the overhang are the dominant processes in non-cohesive dense (sandy) soils under unsteady flow conditions. These processes have been modelled in the present work by an innovative method, which has been validated by field measurements. The results showed that the method enhanced the simulation accuracy up to six times in comparison to the earlier methods.Publicationtype: Doctoral Thesis1149 1949
