Abstract

The long-term physical existence of sandy shores critically depends on a balanced sediment budget. From the principles of Building with Nature it follows that a sustainable protection of sandy shores should employ some form of shore nourishment. In the spatial design process of urbanized sandy shores, where multiple functions must be integrated, the knowledge and the prediction of sediment dynamics and beach-dune morphology thus play an essential role. This expertise typically resides with coastal scientists who have condensed their knowledge in various types of morphological models that serve different purposes and rely on different assumptions, thus have their specific strengths and limitations. This paper identifies morphological information needs for the integrated spatial design of urbanized sandy shores using BwN principles, outlines capabilities of different types of morphological models to support this and identifies current gaps between the two. A clear mismatch arises from the absence of buildings and accompanying human activities in current numerical models simulating morphological developments in beach-dune environments.

Filipe Galiforni Silva, PhD, is a Brazilian oceanographer who has been studying coastal dynamics since 2010. Filipe completed his PhD in 2019 at the University of Twente, The Netherlands, where he studied the dynamics of beach-dune systems near inlets. His research interests lie in the area of coastal modelling, beach-dune dynamics and coastal oceanography.

Hulscher became Simon Stevin master (2016), highest award in the technical sciences. From 2017 Hulscher is member of the KNAW (Dutch academy of sciences).

Paran Pourteimouri, University of Twente

Paran Pourteimouri is doing a PhD in Water Engineering and Management at University of Twente. In her project, she is studying the impacts of buildings at the beach-dune interface on airflow patterns and aeolian sediment transport, using computational fluid dynamics. She is interested in buildings’ characteristics such as dimension, geometry, elevation, orientation and their positioning on the beach.
