PhD Position Hydraulic Boundary Conditions and Loads on Dutch Storm Surge Barriers

Do you want to study the iconic Dutch Storm Surge Barriers, and help to keep them operational for future generation(s)?

Job description
SSB-Delta is a multi-disciplinary project to assess the technical and functional lifetime of the Storm Surge Barriers (SSB)’s and to develop barrier- and delta adaptation pathways as a basis for adaptive decision-making. The project is a collaboration with Universities (TU Delft, Utrecht, Rotterdam) Universities of Applied Sciences (Rotterdam, Vlissingen), Technological institutes (Deltares, TNO) and stakeholders (governmental organisations and industry). The project includes 9 new positions covering a variety of topics. The project will be embedded in ongoing research in the Netherlands and Texas, and strongly linked to international networks like I-STORMS. This position will be hosted by the Hydraulic Engineering Department, a department that stood at the basis of the design of the storm surge barriers and coastal management of the Netherlands. We combine expertise on hydraulic structures as well as on estuarine system dynamics, using numerical models, probabilistic methods, Machine Learning techniques, field measurements, etc.

In this PhD project the hydraulic boundary conditions for the barriers will be studied. This study will go beyond the state of the art, determining the extreme loads on the two major Storm Surge Barriers. This will be done in several separate tasks. First the extreme conditions in both the present and future climates will be described. To this end long duration (thousands of years) synthetic weather patterns of climatic data sets will be analyzed. Machine learning will be used to identify storm patterns of extreme storms. These storm patters can then be used to find the probability of occurrence of certain failure mechanisms (joint probability of governing parameters). For the Maeslant barrier these conditions are mainly dependent on water levels (including long waves and seiches), while for the Eastern Scheldt barrier they are also dependent on the wind wave loading. Next, the load models for the latter wind wave loads on flood gates will also be extended, validated and/or optimised, and the influence of non-linear effects will be determined more exactly. Lastly, a detailed description of the extreme loads on the separate gates of the barriers will be obtained using the outcomes of the preceding tasks, combined with a detailed nearshore wave model that takes into account wave-current interactions in instationary calculations. This will be input for other studies within the research programme.

The maintenance and operation of storm surge barriers is a very interdisciplinary team effort. Therefore, in this project you will have to interact and cooperate with many other researchers, and people from Rijkswaterstaat and the many other (industry) partners.
