Abstract:Scour, an engineering term for erosion, is
the result of the erosive action of flowing
water excavating and carrying away
material from the bed and banks of
streams and from around the piers and
abutments of bridges. For analysis
purposes, total scour at a bridge
foundation consists of three independent
components: (1) long-term aggradations
or degradations of the river/stream bed,
(2) general scour (including contraction
scour) at the bridge, and (3) local scour at
the piers or abutments of the bridge.
