Abstract

Recent research studies revealed that most bridge piers and other hydraulic structures such
as levees and embankments adopted in flood protection schemes in maritime environment have
collapsed due to the failures attributed to scour associated with a soil–hydrodynamic interaction
phenomenon (e.g. Shirole and Holt, 1991). Though erosion characteristics of coarse sands and gravels
are relatively well known, soil-hydrodynamics interaction for finer sands such as silts and clays is not
fully investigated. A series of small-scale laboratory experiments were conducted in a moveable
sediment tank to investigate scour characteristics under various flow and soil conditions. The present
paper discusses preliminary experimental observations and the analysis of hydrodynamic erosion of
soils in line with the extensive research project „Mathematical and Physical Modelling of
Hydrodynamic Erosion of Soils (HES)‟ carried out under the „UEL Promising Researcher Fellowship
2009-2010‟ funded by the University of East London (UEL).
