With 40% of the world's population living within 100 kilometers of the coast, and with extreme weather conditions intensifying as the average global temperature increases, coastlines are in danger of eroding, leaving many communities vulnerable to damage by waves and flooding. This project focused on the effectiveness of flexible vegetation as a non-invasive, sustainable, and resilient shoreline protection alternative. An ideal model was developed through meta-analysis and subjected to multiple wave conditions, at two different water depths, to determine the effect of vegetation emergence and submergence on wave attenuation. Emergent vegetation resulted in smaller average and significant transmission coefficients (Kt,mean=0.598-0.697 and Kt,significant=0.332-0.393) and greater wave height percent differences due to interruption of the entire wave velocity profile.
