Every year a large number of bridges flooding in the river just when they most need them there destroy all born. Carried out. In this study, the four fulcrum forms a semi-circular, trapezoidal, rectangular edges rounded rectangle 90 degrees at 70 degrees in Sagittarius with four different discharges depth of constant scouring around the abutment in pure water were examined. For material of flume natural sand with uniform grain size was 1.59. The results showed support by forming a semi-circular and rectangle 90 degrees was significantly minimum and maximum the scour hole around them. In all abutments with increasing Froude number, scour around them also increased.
