Two kinds of sands and three sizes of circular piers were used in this experiment, and 16 runs were performed under different flow conditions. Some equations found by other investigators are discussed in relative to the results obtained from this study and finally a design criterion for estimating the likely scour depth of the circular pier for the case of scour with continuous sediment motion is established. 0aScour and fill (Geomorphology) 0aBridgesxFoundations and piers1 aOverbeek, Henk Jen, eChairperson0 aTawatchai Tingsanchali, eExamination Committee0 aPrida Thimakorn, eExamination Committee1 aChian-Min, Wu, eExamination Committee2 aCarl Duisberg-Gesellschaft, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
