Automated Wave Overtopping Calculator for Coastal Defence Design

The Challenge

Coastal and flood-defence engineers were calculating wave overtopping discharge by hand using the EurOtop empirical methods — slow and repetitive across many design permutations. Re-running the numbers for every change in wave height, water level or structure geometry made iteration painfully slow and risked transcription errors.

The Solution

We built an automated tool that takes the governing inputs — significant wave height and period, still water level, crest freeboard, slope and structure geometry, armour roughness and wave obliquity — and instantly returns the mean overtopping discharge, comparing it against tolerable limits for pedestrian, vehicle and structural safety. Engineers sweep through variants in seconds and converge on a compliant crest level with confidence.
