Abstract

This paper highlights the probable causes of failure of existing bank protection works of the River Surma for safety of Sylhet, the northeastern city of Bangladesh. In this study, eight places were selected where the concerned authority implemented bank protection works. Observation shows that the soil particle of the embankment carries significant amount of clay, fine silt and fine dust, indicating that the soil of such areas is subjected to be eroded, which poses a great risk to the safety of this city. Moreover, the grain size analysis of all the selected locations shows that the effective diameter (d10) of the soil sample is much lower than the value used in the design calculation of the authority. In consequence of this the scour depth would be more than the calculated one. However, the study will give a better understanding of those factors causing deterioration to the protective structures.
