Directional spectrum, also known as wave directional distribution, refers to the distribution of wave energy as a function of direction. In oceanography, it is a crucial tool for understanding the behavior of waves in the ocean and plays a significant role in coastal and offshore engineering. Understanding directional spectrum helps in predicting wave characteristics, wave-induced forces, and sediment transport. In the field of remote sensing, directional spectrum is used to analyze radar and satellite data to study ocean waves and currents. Additionally, directional spectrum is utilized in the design of offshore structures and the development of wave energy converters. Overall, the study of directional spectrum provides valuable insights into the complex behavior of waves and their impact on the environment and infrastructure.
