A series of mobile bed model tests of a prototype circular sand island was performed to determine scale effects. It was found that scale effect was largely a function of mobility number with some secondary effects of Reynolds number, bedform and critical profile depth. It was concluded that a model series using prototype sand grain size is necessary at this time to effect successful extrapolation to prototype.
