Abstract


Wind is a major energy induce wave and sea surface current; the worst impact known as storm surges. Measurements related to the wind patterns may indirectly reflect the condition of waves and the sea surface current. The aim of this research was to discover the correlation between wind direction and sea surface current in Brebes and Kendal Coastal Area, focusing on the nearshore zone. Sea surface current measured by a simple measuring instrument that was constructed to determine the direction and speed of sea surface current. The results showed 100o-300o differences between wind direction and sea surface current direction. However, the results showed that the existence of river mouth is the main factor that influences the different pattern of the sea surface current and wind direction. It was shown by the linearly of the water mass and major movement of sea surface current direction. The substantial role of the stream also proofed by the accidence of disappearing of some people in the river mouth, which means the energy of the stream, as subsurface current, took a huge amount of the kinetic energy in the coastal area and as evidence of the outlet current.
