Deltas are under pressure due to climate change and increasing human activities, resulting in gradual or rapid changes in their abiotic and biotic systems. Especially when these pressures exceed certain thresholds these changes may be abrupt or even irreversible (i.e. regime shifts). The transitions of deltas are complex as human impacts operate on a wide range of spatial and temporal scales, while internal buffers and processes in the systems also set specific reaction time scales. Identifying how relevant physical and biological processes interact at different spatial scales, and thereby shape the resilience of estuarine systems, is crucial for understanding and optimizing the adaptive capacity of estuaries.
An extensive research program is set up to identify and determine the relevant thresholds, regimes and time scales, and to explore measures for coping with the transitions. Delft University of Technology is intensively collaborating with State Key Laboratory for Estuaries and Coasts (SKLEC) in Shanghai and Dutch partner Netherlands Institute for Sea Research (NIOZ) in Yerseke.
This PhD project focuses on large-scale regime shifts in estuarine morphology. The focus will be on the Yangtze, Scheldt and Ems estuaries, which are all highly impacted by human interferences. The aim of this study is to identify and explain the complex relationship between human interventions and large-scale morphological changes. This will be done by applying and developing idealized models, applying detailed process-based numerical simulations and analysis of field data.
We are looking for a highly motivated candidate with a Master's degree in the field of Coastal Engineering, Physical Geography, Environmental Engineering or related field, with a solid background in the dynamics of tides, waves and morphology. The ideal candidate would: (1) have a keen interest in doing fundamental research, which can be translated into applicable knowledge; (2) be highly motivated to collaborate with the Chinese and Dutch partners, implying staying (short) periods in Shanghai and Yerseke; (3) be skilled to apply and improve numerical models; (4) be capable of unravelling physical and biological mechanisms from large datasets. Communication skills and an open, collaborative attitude are essential in this multidisciplinary project. Good English speaking and writing skills are demanded.
