Abstract

Lave bølgebrydere anvendes ofte som erosionsbeskyttelse til sikring af kysten. Afhandlingen omhandler hvorledes stabiliteten af disse opnås gennem passende valg af stenmaterialer. Baseret på modelforsøg præsenteres designformler til fastlæggelse af tilstrækkelige stenstørrelser. Endvidere beskrives stenmaterialernes indvirkning på de lokale biologiske forhold.
