What is it about?
This paper examines the sudden and powerful forces generated when a wave (like the ones you see on a beach) strikes a solid wall, such as a seawall, a ship's hull, or an offshore platform. Rather than using a simplified model, the author applies advanced mathematics (nonlinear potential flow theory) to calculate the forces striking the wall; predict the shape of the water surface during the collision; and focus on the first few moments after the wave impact, when the forces are strongest and most unpredictable. This approach avoids assumptions and more accurately describes how energy is transferred from the wave to the wall.

Why is it important?
Real-World Relevance: Breaking waves can cause severe damage to ships, oil rigs, and coastal defenses. These impacts, while brief, are incredibly powerful. Engineering Safety: Conventional wave models often underestimate these forces. This paper aims to help engineers design structures that are better able to withstand wave impacts. Scientific Advancement: It deepens our understanding of wave behavior during collisions, which is crucial for both civil and marine engineering.
Perspectives
Engineering Applications: These findings have direct implications for designing safer marine and coastal structures. Scientific Contribution: This paper eliminates the guesswork involved in determining wave shape and addresses the problem analytically. Future Research: The method could be extended to study waves impacting at angles, moving walls, or more complex fluid interactions, bringing us closer to simulating real-world ocean conditions.
