Abstract

Local abutment scouring leads to the failure of highway bridges in extreme cases. In this research work, experiments were performed in order to estimate the effect of vegetation on local scouring around abutment under two different scenarios i.e. with and without channel bank vegetation. It was observed that vegetation on channel banks resulted in reduced local scouring around the abutments. The scour depth around abutments with vegetated bank was half of the scour depth as compared to that of non-vegetated banks. The time for attaining the equilibrium condition after sediment scouring in case of vegetated banks was reduced 42% as compared to that of non-vegetated banks.
