The mechanism of sediment control of side weir is investigated with attention focussed on bed load and bed variation, using a rectangular flume with main and side weirs.
Discussions are made on the energy-loss due to local flow around the weir, the relation between the sediment rating curve and bed variation, the diversion ratio of sediment and the dividing discharge ratio. Such sediment phenomena can be evaluated roughly in terms of one dimensional analysis.
