As presently used, the immersed weight rate, I sub l, is the volume rate, Q, of longshore transport, multiplied by a constant. For use in engineering problems, I sub l must be converted back to the equivalent Q. The I sub l formulation may be important where the unit weight of sand differs significantly from the unit weight of sand at the open-coast sites contributing data to the design curve. Increase in void ratio may result in a 10- to 20-percent increase in actual (as compared to predicted) shoaling volumes where sand accumulates in protected water. Void ratio should be measured in field studies of longshore transport.
