In the study the effect of collars on scour for spill-through abutments under clear-water conditions was investigated. Total of 70 experiments were conducted. Two abutments were placed on the opposite sides of a straight rectangular channel. Collars with different widths were placed at different depths around these abutments and reduction on scour was investigated for each case. Using different abutment lengths allowed investigation of collars at different contraction ratios and hence optimum collar configuration and depth was defined for abutments with various contraction ratios. It is concluded that collars are effective in reducing scour and protecting spill-through abutments against scour.
