![]() The method used to sample deposited hopper sediment identified a bias in the percent fines that resulted from flow sheltering. Results showed that no statistical difference exists among the three methods used to sample the hopper weir overflow. This report focuses on laboratory experiments aimed at determining (1) suitable sampling methods on a dredge, (2) composite sampling techniques to reduce analysis cost, (3) associated sampling intervals to achieve suitable sediment representation of a hopper load, and (4) a hydraulic means of sample splitting. The degree of separation and the controlling factors are presently poorly known. Hopper dredging operations for beach and nearshore placement typically include periods of overflow, which produces some degree of separation between the size fractions of the dredged sediment.
