Model layout The existing causeway and revetment adjacent to Nome Harbor, as well as the proposed jetties and breakwaters, are rubble-mound structures. Experience and experimental research have shown that considerable wave energy passes through the interstices of this type structure; thus, the transmission, reflection, and absorption of wave energy became a matter of concern in the design of a 1:90-scale model. In small-scale hydraulic models, rubble-mound structures reflect relatively more and absorb or dissipate relatively less wave energy than geometrically similar prototype structures (LeMehaute 1965). Also, the transmission of wave energy through a rubble-mound structure is relatively less for the small-scale model than for the prototype. Consequently, small-scale model rubble-mound structures must be adusted somewhat to ensure satisfactory reproduction of wave-reflection and wave- transmission characteristics. In past investigations (Dai and Jackson 1966, Brasfeild and Ball 1967) at WES, this adjustment was made by determining wave- Chapter 2 The Model.
