Schematic of the streamer trap rack streamer trap in intersecting oscillatory and quasi-steady uniform flow in the surf zone is not known, but qualitative observation in the field indicates that surf zone efficiencies may be approximated by efficiencies determined in the uniform flow tank under sheet flow conditions. 25. To measure the transport rate, the traps (denoted by symbols Tl to T7 in Figure 2) were carried to predetermined positions defined by reference to the photopole line and an additional line of survey marker

To measure the transport rate, the traps (denoted by symbols Tl to T7 in Figure 2) were carried to predetermined positions defined by reference to the photopole line and an additional line of survey marker poles placed parallel to the photopole line. Typically, one person carried and operated one trap; however, two operators were sometimes necessary near the breaker line. At a signal, the racks were simultaneously thrust into the bed with the 20
