 This study focused on the alignment of spur dikes fixed on rigid-bed fields, and discussed the effect of angle of spur dikes on the characteristics of flow, sediment transport, and bed variation. The results show that acute-submerged spur dikes (30-degree) significantly produced sediment deposition areas between spur dikes, because the flow in the upstream area of acute-submerged spur dike was divided into two directions. One of the flow directs toward the main flow and transports sediment to the main flow from the spur dikes. While, another flow directs toward the joint between the spur dike and the fixed wall. The later flow transports bed load material into the upstream area of the acute-submerged spur dikes and the material deposits there or passes over the dike and deposits between spur dikes.
