Verhagen, H.J. (author), Struik, P. (author)Tegenwoordig is bijna elk probleem bij de versterking van dijken op te lossen door een kunstwerk te maken in plaats van de traditionele grondconstructie. Soms wordt bij de afweging te weinig rekening gehouden met de lange levensduur en de bijzondere aard van' de waterkering'. Dat kan toekomstige generaties met grote problemen opzadelen.journal article 1993

Het primaire doel van iedere waterkering is het keren van water.

(author)In the Netherlands today much attention is paid to the effect of coastal structures on the environment.
