Direct methods are used in literature, dealing with abutments-scour problems, such as placed rocks, riprap or flexible mattresses around the abutment foundation. This studies an indirect one that examines the effect of using submerged panels around the abutment. Experiments conducted in clear-water conditions. The angle of the panel is 135°, the width of the panel is 63 cm, the distance between panel and abutment equal to 0 cm, depth of panel with the submerged water is 1 cm. They can reduce scour depth as much as 99% in final equilibrium.
