STABILISATION OF THE TIDAL ENTRANCE AT HORNAFJORDUR, ICELAND

[摘要] Hornafjordur is a tidal entrance on the south-east coast of Iceland, a shore with a heavy littoral drift. An extreme storm hit the coast in January 1990. It caused large shoaling to encroach upon the entrance channel from both sides, and a breakthrough occurred between the rock headland Hvanney and the South Barrier. The inlet was closed for several weeks. A rubble mound shore protection was built on its west side in 1991 to restore the South Barrier. A curved breakwater of berm type was constructed during the summer 1995. Due to severe wave action and strong current a berm structure with toe protection was chosen. The paper presents the experiences gained on the tidal inlet based on hydrodynamic and hydraulic models, both calibrated to the field data.
