Are you interested in innovative, nature-based solutions to enhance flood protection of coastal areas around the world? At the Water Engineering & Management department we have an active and dynamic group of researchers pioneering in nature-based engineering.
In this position you will study the resilience of coastal mangrove systems and their contribution to coastal safety. Mangrove ecosystems are known to significantly reduce flood risks in low-elevation coastal areas, well-known hotspots for population growth and economic development. Mangroves’ capacity to attenuate hydrodynamic forces and to accumulate sediments also provides them with a natural resilience to buffer the impacts of flood events and to adapt to changes in environmental conditions. Nevertheless, mangroves are increasingly stressed by decreasing sediment supplies, accelerated sea-level rise and other anthropogenic impacts. Critical thresholds to mangrove resilience may be reached and quantitative insights into how such factors affect biophysical interactions in mangroves are required to develop predictive models to help assess mangrove shorelines’ vulnerability as well as their contribution to coastal safety.
Assessing and predicting mangrove resilience is challenging because of the disparity between short-term and longer-term biophysical dynamics in these ecosystems. The aim of this PhD position will be to bridge the gap between short-term and long-term morphodynamics in mangroves ecosystems, by combining field observations with numerical simulations. Field observations will be instrumental in obtaining a mechanistic understanding of the morphological development of mangroves. You will then use these insights to develop a numerical model able to predict both the short-term and long-term biomorphodynamic development of mangroves and its sensitivity to the effects of climate change and other anthropogenic impacts. The aim is to quantify mangrove resilience, thus enabling the assessment of mangroves’ integrity and contributions to coastal safety, now and in the future.
This PhD position is part of the Mangrove-RESCUE program, ‘Mangrove Resilience for Enhanced Safety of Coastal Urbanisations and Environments’. Within this program, you will collaborate with a wide range of partners in the Netherlands and overseas.
