A comparative study on the performance characteristics of buffer blocks configurations as energy dissipators

This study examines the effectiveness of buffer blocks in dissipating the flow due to extreme events along the coasts using the numerical modelling approach. Initially, the study explores the effect of the number of rows of buffer blocks on the reduction of momentum flux. After establishing that the three rows configuration are the most efficient, subsequent analysis were carried out which include the understanding in the variations of block heights, including adjustments in height ratios between rows and by arranging blocks in increasing or decreasing height within the rows. Through a systematic examination of these configurations, the study aims to determine the most effective setup for maximizing energy dissipation of flow characteristics during extreme events such as tsunamis and storm surges.
