However, the influence of hand versus mechanicalshaking methods has not yet been studied. Herein, samples were taken from inside the hopper ofa trailing suction dredger and sieved by hand with sieves of 10 and 20 cm diameters on board thedredger. Afterwards, these same samples were sieved with a mechanical shaker in the laboratory onland. The results showed di erences for the main size parameters D50, standard deviation, skewness,and kurtosis. Amongst the main results, it should be noted that the highest values for D50 andkurtosis were given by the small sieves method. On the other hand, the lowest values were given bythe mechanical shaker method in the laboratory. Furthermore, standard deviation and skewness didnot seem to be a ected by the sieving method which means that all the grainsize distribution wasshifted but the shape remained unchanged. The few samples that do not follow these patterns have ahigher percentage of shells. Finally and definitely, the small sieves should be rejected as a sievingmethod aboard.
