One of the urgent challenges of our time is to prepare for the inevitable effects of global climate change. In densely populated deltas around the globe, hard structures such as dikes covered with asphalt are commonly used as coastal protection measure. Such structures are static and will not withstand the rising sea levels and increased storminess. In the Netherlands alone, it would cost billions of Euros to heighten these dikes in the coming years. Instead, soft solutions – coastal wetlands – could be placed in front of the dikes and the asphalt could be replaced with grass. Such systems are climate-adaptive as they capture sediments and grow with rising sea level and resilient as they buffer coast against storms by reducing wave-loading. Within the NWO funded research project “Living Dikes”, we aim to develop the know-how and the design tools for realising these living dikes.
In this PhD project, which is embedded in Living Dikes, you will focus on the erosion and stability of living dikes under extreme storms. First, tests will be performed in the TUDelft wave flume (1 m deep, 40 m long) to obtain crucial knowledge on wave damping, pressures, bed shear stresses and run-up on scaled living dikes. The vegetation will be modelled with individual plastic plants made of low-density polyethylene (LDPE). The results will help to design the layout of the Delta Flume experiment. For this Delta Flume experiment, we will grow and transplant wetland and dike vegetation into large basins to mimic a range of field conditions. Vegetation and soil from various locations will be transplanted into the Delta Flume (300 m long, 5 m wide and 9 m high) to create a natural wetland and transition area between wetland and dike. This wetland will be tested under extreme conditions (storms occurring once every 10,000 years). These will be the first tests that specifically address living-dike stability under such extreme environmental conditions. We aim to test man-made living dikes with contrasting characteristics (i.e. soil mixture, vegetation type, presence/absence of wave-breakers). This will yield a clear understanding of the main failure mechanisms that affect the stability of the living dike. Moreover, a comprehensive dataset will result on the basis of which models can be developed to assess the reliability of living dikes impacted by severe storms.
The Living Dikes project is a collaboration between the Marine and Fluvial Systems (MFS) group at the Department of Civil Engineering of the Faculty of Engineering Technology, the Faculty of Technology, Policy & Management at TU Delft, the Faculty of Civil Engineering at TU Delft, and the Royal Netherlands Institute for Sea Research (NIOZ). In this PhD-project you will be supervised by a team from the University of Twente, with close collaboration with the involved partners.Your profile
We are looking for a talented, enthusiastic researcher with an active attitude and broad interests covering coastal dynamics, modelling, biogeomorphological interaction, hydraulic engineering and an affinity with flume experiments. Your MSc is in Civil Engineering, Geosciences (e.g. Physical Geography or Geophysics), Environmental studies or a related field. We consider it important that the candidate is able to view his/her research from a broader perspective (within Living Dikes project, the scientific world and towards the practical application) and that he/she is willing and able to collaborate closely with other researchers in the project and involved users in the team. Therefore, we welcome entrepreneurial candidates with an open mind, strong communicative skills and excellent comprehension of English, in both spoken language and writing (IELTS >= 6.5 or equivalent). Some of the desired skills can be acquired during an individual training program of 840 hours that is part of the PhD project.Our offer
