Water controlling water

TL;DRAbstract

This project discusses the feasibility and effectiveness of emergency measures against river floods. The objective of the project is: To develop a method or system to temporarily increase the dike strength during flood wave conditions. Here, the dike strength in its broadest sense is meant. This means that besides the crest height also other properties are considered. Generally, the dike height is designed with respect to a certain normative water level. The protection level is herewith based on the overtopping and overflowing mechanism. Besides overtopping and overflowing other mechanisms, especially piping, could contribute to dike failure. The project further focuses on these two failure mechanisms. The proposed emergency measure against overtopping is the traditional temporary crest heightening. The proposed measure against piping is the creation of a water berm at the inner side of the dike. The latter decreases the head difference between the river and land side of the dike by in
