EFFECTS OF DIURNAL VARIATION OF WAVES DRIVEN BY LAND AND SEA BREEZES ON SEDIMENT TRANSPORT AROUND THE NORTHWESTERN COAST OF JAVA ISLAND, INDONESIA

Abstract

 We carried out numerical simulations on waves and sediment transport aroud the Patimban coast, where is located in the northwestern part of Java Island, Indonesia, to investigate characteristics of waves driven by land and sea breezes and its effects on sediment transport aroud the study area. The simulated wave fields were strongly affected by diurnal variation of the sea surface winds due to the sea breezes. The simulated bed level changes at the depth of less than 10 m were different under only the land breeze, or both the land and sea breezes. The phase relationship between diurnal variations of the tidal currents and waves have an important roles on not only erosion and horizontal transport pattern of the suspended sediments.
