The great variation in velocity of the moving water in the swash and backwash causes extensive sorting of the beach material. As a result there are considerable differences in the rate at which beach sediments of various sizes are transported. Mechanical analyses were made of the beach sands to show the amount and character of the sorting. Also the behavior of suspended sediments in the swash and backwash were observed to determine the peculiarities of transportation. The conclusion is reached that it is the sediments of medium size that are transported most rapidly by beach drifting.
