BRIDGE PIER SCOUR IN GRAVEL BED RIVERS

Kothyari, U. C. / Garde, R. J.

This paper presents a critical note on the practice being followed in India for estimating the design scour depth around bridge piers founded in the gravel bed rivers. Limitations of the provisions existing in the engineering codes of Indian practice are illustrated through examples and the methods recently developed through scientific investigations for estimation of the scour depth are described. A new relationship is proposed for the Lacey's silt factor estimation in gravel bed rivers. The discharge intensity based Lacey-Inglis procedure when used in conjunction with the relation for estimation of the silt factor proposed herein is expected to produce realistic estimates for the scour depth around bridge piers founded in the gravel bed rivers.
