Exchange of Young Researchers within the THESEUS project
Siddharth Narayan is a THESEUS-funded PhD student at the University of Southampton, under the supervision of Prof. Robert Nicholls and Dr. Derek Clarke. His PhD topic is "Development of A 2D Modelling Framework for Quantitative and Qualitative Risk Assessments of Coastal Floodplain Systems." As part of his PhD, Siddharth spent one month at KULeuven under the supervision of Prof. Patrick Willems and Prof. Jaak Monbaliu investigating the application and effectiveness of the 2D Source-Pathway-Receptor (SPR) model in the Dendermonde region of the Scheldt-Dender basin in Belgium.
He says: "I am extremely grateful to Prof Patrick Willems, Prof Jaak Monbaliu, Prof Robert Nicholls, Dr. Derek Clarke, and the THESEUS project for this unique opportunity to test and extend my PhD work in KU Leuven. I am very grateful to my research colleagues Duc Anh Nguyen, Vincent Wolfs, Qilong Bi and others at KU Leuven for their extensive help and cooperation during my stay there.
The aim of my work here was to use the 2D SPR model to capture and assess relationships between land-use and flood risk levels for the Dendermonde region of the Scheldt-Dender river basin using a systems approach. This work is an extension of previous collaboration with KU Leuven on applying the conceptual 2D SPR model for the Scheldt basin and the Dendermonde region. The conceptual model highlighted the advantages of the 2D SPR approach as a truly integrative and comprehensive method of studying complex floodplains. This is now being extended to a simplified quantitative modelling framework to assess dynamic changes to floodplain system characteristics. The main objectives of the work are as follows:
Source-Pathway-Receptor (SPR) maps for the Dendermonde estuary
It is expected that the results from this work will provide a novel rapid, robust and scalable method for assessing the effects of land-use changes on floodplain flood risk levels. The work done at KU Leuven has also been very helpful towards achievement of my PhD objectives and will hopefully lead to further collaboration in the area in the near future."
