| Summary: | Wave is a natural phenomena occured in the ocean. The waves carry energy that gives effect to the coastal areas. The impact can be positive or negative effects. A sample of negative impact is the phenomena of abrasion. Abrasion is caused by the energy carried by the waves over time that will erode the coast. An area that have an abrasion impact of coastal wave is Muara Gembong District. To overcome the negative impact of the waves required a research about waves that caused the abrasion. An answer to these problems is the calculation of wave climate using wind data. Calculations performed with the wave characteristics in the area can be seen as an initial step to determine ways to overcome them. In this study will be used several methods of calculations, such as JONSWAP, SMB, Ozeren, and Donelan. Wave climate calculations carried out at 15 points spread along the coast of Muara Gembong District. The calculations of all observations points show that 11,04% wave come from the North, 7,98% from the Northeast, 11,65% from the East, 9,8% from the Southeast, 4,2% from the South, 4,14% from the Southwest, 16,55% from the West, and 34,64% is from the Northwest. The important factors in the occurence of these waves are the magnitude of wind speed and fetch. |
