Abstract: Sediment threshold experiments were conducted in two types of rigid boundary Vshaped drainage channels, commonly used in bridge kerbside drainage units. Sand and gravel particles were used and the slope-discharge relationships found for threshold conditions. Comparisons were made with the Shields (1936) threshold criterion and the Ackers& White (1973) total load function. The latter equation was found to be more appropriate for design purposes.
