Random waves are the most important constituent of the sea environment, as they make the design of maritime structures quite different from that of structures on land. In this book, the concept of random waves for the design of breakwaters, seawalls, and harbor structures is fully explored for easy comprehension by practicing engineers. Theoretical aspects are also discussed in detail for further studies by graduate students and researchers. Contents: Random Sea Waves and Engineering Applications: Introduction; Statistical Properties and Spectral of Sea Waves; Generation, Transformation and Deformation of Random Sea Waves; Design of Vertical Breakwaters; Design of Coastal Dikes and Seawalls; Probabilities Design of Breakwaters; Harbor Tranquility; Hydraulic Model Tests with Random Waves. Statistical Theories of Random Sea Waves: Description of Random Sea Waves; Statistical Theory of Irregular Waves; Techniques of Irregular Wave Analysis; 2-D Computation of Wave Transformation with Random Breaking and Nearshore Currents. Statistical Analysis of Extreme Waves: Statistical Analysis of Extreme Waves. Waves and Beach Morphology: Coastline Change and Coastal Reconnaissance; Prediction and Control of Shoreline Evolution.
