The perpose of the present investigation is to evolve a present measure the scour around a circuler cylinder. The down flows from horse shoe voltex have a important role on the scocr around a circuler cylinder. It is indicate the posibility of the prevent of scour around a circuler cylinder from control tbe horse shoe voltex by a horizontal rectanguler groove at vicinity of river bed. We describe an experimental study on the scour around a circuler cylinder with a horizontal rectangular groove and discussed them in this paper. It became clear after examining the experimental results that a horizontal rectanguler groove is very useful method to prevent the scotar around a circuler cylinder an the scour depth around a circuler cyliader decreased approxiaately 20~50% by set up a horizontal rectangular groove around a surface of circuler cylinder at vicinity of river bed.
