To quantify the effect of a current on the height of a wave’s run-up and overtopping combined with an oblique wave approach, the “FlowDike” hydraulic research project was carried out. Tests were performed on two dike slopes of 1:3 and 1:6. Waves were generated across (perpendicular to) the physical model and also inclined in-plane to the stream axi...
Article
Under the scope of the HYDRALAB+ transnational access project, the so-called RODBreak experiment was conducted in the multidirectional wave basin at the Marienwerden facilities of the Leibniz University Hannover (LUH). A stretch of a rubble-mound breakwater was built in the wave basin with a very gentle slope. Its armour layer was made of Antifer c...

The existing data gaps triggered the interest in developing the present experimental work, whose main goal is to contribute to a new whole understanding of the phenomena to mitigate future sea level rise impacts in European coastal structures, including the run-up and overtopping characterization on rough and permeable slopes. The key point is to e...

A set of scale-model tests carried out to enlarge the range of wave steepness values analysed in run-up, overtopping and armour layer stability studies, focusing on oblique extreme wave conditions and on their effects on a gentler slope breakwater’s trunk armour and roundhead, is presented in this paper. A stretch of a rubble mound breakwater (head...

Although dams are very safe structures a residual risk remains. This should be minimized by means of technical and organizational measures. This paper outlines the status quo of dam safety in Germany focusing on medium and small dams. Often, the owners and operators of these structures are not experts. The establishment of a register for small and...

Dam break wave simulation provides data for emergency management. The calculation results should be as accurate as possible. The modeler has to deal with different sources of uncertainty. The paper presents dam break calculation for three different dams in order to assess the uncertainty due to the chosen model (1D or 2D), different terrain models...
Article
Implementing new concepts and measures for flood risk management may be restricted by hydromechanical processes. These processes govern the movement of water masses within rivers and their floodplains. Different hydraulic processes are still not fully understood or cannot be described satisfactorily by hydro-numerical models due to uncertainty in i...
Article

Der Wellenauflauf von Windwellen ist eine der maßgebenden Größen in der Freibordberechnung. Obgleich bereits eine Vielzahl an Ergebnissen zum Wellenauflauf aus langjährigen Versuchen veröffentlicht worden sind, gibt es immer wieder Fragestellungen bei speziellen Randbedingungen, die oft nur mit Hilfe von Modellversuchen beantwortet werden können. I...

Article
Full-text available
Flow processes like flow depths and flow velocities give important information about erosion and infiltration processes, which can lead to an unstable dike structure and consequently to dike failure. Up to now several physical model tests on wave run-up and wave overtopping are available to adjust and improve design formula for different dike struc...

In den 10 Jahren, die seit dem Extremhochwasser in Sachsen vergangen sind, wurde viel für den Hochwasserschutz getan: die Vorhersage, die Kommunikation sowie die Hochwasserschutzanlagen wurden verbessert und es wurden neue Deiche sowie Hochwasserrückhaltebecken errichtet oder angepasst. Eine wichtige Frage ist aber, wie sich das Hochwasserbewusstse...

Since the extreme flood in Saxony in 2002 much has been done for flood protection during the last decade: prediction, communication and flood protection have been improved. New levees, protection works and flood retaining reservoirs have been built or upgraded. But a very important question is how the flood awareness of the people at risk has devel...

Wave run-up on Levees under Complex Boundary Conditions The wave run-up height is, along the predominant water level, a decisive factor in the design of the crest height of levees and dams. Although various results about wave run-up already had been published, questions with specific boundary conditions regularly occur. Most of them can only be ans...

Intention of the project FlowDike-D is to quantify the impacts of current and wind on wave run-up and wave overtopping and to consider these processes in existing design formulae for estuarine, river and sea dikes. Physical model tests were carried out in the shallow water basin at DHI (Hørsholm/Denmark) for two different dike geometries (1:3 and 1...
Conference Paper
Full-text available
Based on the analysis of former dam break case studies a method will be established to estimate the maximum discharge downstream a broken dam. The method uses dimensionless parameters standardized with the peak discharge, the reservoir water level before dam break and the outflow volume. Results are the possible maximum water level at a certain poi...

Owners and operators of facilities with a high risk potential are obliged to inform the appropriate authority of possible consequences of a failure. For the unlikely event of a dam break information concerning this matter can be acquired.
Article
Eigentümer und Betreiber von Anlagen mit einem großen Gefahrenpotenzial sind gehalten, den zuständigen Behörden Auskunft über mögliche Folgen eines Störfalles zu erteilen. Für den unwahrscheinlichen Fall des Bruches eines Absperrbauwerkes können diesbezügliche Informationen erarbeitet werden.
Article
Owners and Operators of installations and plants with a high hazard potential including dams are due to inform about possible risks. This will help to detect hazards and to take measures if necessary. For operators of reservoirs and dams this means to provide inundation maps not only about the consequences of natural floods but also about the flood...

Das Versagen einer Talsperre mit einer sich anschließenden Entleerung des Stauraumes ist sehr selten. Jedoch zogen solche Ereignisse in der Vergangenheit immer große Schäden nach sich, so dass trotz der geringen Eintrittswahrscheinlichkeit das Risiko als hoch einzuschätzen ist. Der Beitrag behandelt die Erstellung von Gefahrenkarten, die Auskunft d...
