Coastal Breakwater + Seawall Designer — Ebora

🌊 Coastal Breakwater + Seawall Designer

Design coastal protection two ways: a rubble-mound breakwater with the Hudson formula (armor-unit weight, layer thickness, units per m², crest width, underlayer/core sizing), or a seawall from wave run-up (deep-water wavelength, surf-similarity number, required crest elevation). With a section sketch, worked steps, and a PDF.

Worked solution

⚠️ Indicative design. The Hudson K_D, layer coefficient k_Δ, porosity and run-up roughness γ_f come from SPM / Coastal Engineering Manual (CEM) tables and vary with armor type and damage level — verify against SPM/CEM and DPWH coastal criteria, and check newer methods (van der Meer) before design.
