ABSTRACT
Flood protection works like levees, floodwalls and demountable elements (mobile floodwalls) have to protect people and assets in the hinterland. Freeboard design is an important part of the proper design of these structures. The relevant German standards and technical guidelines for levees are setting the frame for the freeboard allowance but the real procedure is usually adopted from a former technical guideline for lakes and reservoirs, i.e. for still waters. Preparing the update of the freeboard guideline, investigations have been made concerning the special situation at fluvial levees and the potential wind wave run-up and overtopping under these boundary conditions. This paper presents pertinent results of the related laboratory experiments and its influence on the freeboard design.
