Understanding Coastal Dynamics: Waves, Currents, and Lighthouse Insights

DESCRIPTION

This chapter explores the intricacies of coastal environments, comparing active and passive margins. With a focus on Morris Island Lighthouse in South Carolina, it highlights the significance of coastlines where 53% of the U.S. population resides in coastal counties. The chapter delves into deep-water wave forms, factors controlling wave dynamics like wind speed and fetch, and the characteristics of different wave types such as plunging and spilling breakers. This knowledge is essential for understanding coastal erosion, human impact, and infrastructure resilience.
