The relation between the scour depth (R) and Regime scour depth (Re) for an alluvial river having regime width (W) and contracted width (B) is given by ______
The relation between the scour depth (R) and Regime scour depth (Re) for an alluvial river having regime width (W) and contracted width (B) is given by ______ Correct Answer R = Re (W/B)0.61
For purely alluvial streams, the Lacey’s scour depth (R) is given by R = 1.35 (q2/f)1/3 where q is the discharge intensity per unit width of the stream at the bridge site. The value of Lacey’s regime scour depth (Re) is given by R = Re (W/B)0.61.
