Reflection and Transmission Characteristics of Porous Rubble-Mound Breakwaters offers practical methods for coastal engineers to predict how waves interact with porous breakwaters.
This non-fiction study examines how porous rubble-mound structures reflect and transmit wave energy. It presents a self-contained approach by introducing empirical relationships for the hydraulic behavior of the porous material and an empirical friction factor to express energy dissipation on the seaward slope. The work aims to help engineers assess how much wave energy will transmit through a breakwater and how much is reflected back toward the sea.
The content includes procedures for predicting both reflection and transmission coefficients, accounts for energy losses due to bottom friction, and discusses how runup relates to these predictions. It also covers rough and smooth slope behavior and provides guidance on applying the results to trapezoidal, multilayered breakwaters and equivalent rectangular representations. The material emphasizes the limitations of the models and where the empirical relationships are valid.
