View on the coast
Daphne van der Wal – physical geographer at NIOZ and professor at the University of Twente – observes deltas, coasts and estuaries from space and from the air. ‘That can be done via satellites but also with the help of drones. The use of these remote sensing techniques can teach us a lot about coastal defence, water quality and nature conservation.’
Protection against storms
‘Satellites have the advantage that, in many cases, they allow us to look back over several decades. This is because we have a long history of satellite images which have continually observed a piece of the Earth’s surface in the same way. For example, from satellite images, we can see where coastal vegetation, such as saltmarshes and mangroves, has expanded and where plants have disappeared or where their growth was hampered. We analyse satellite images in relation to coastal protection for the Dutch coast, but also for the coast of Louisiana, for example. Together with modellers, we are examining how vegetation attenuate the waves and trap sediments and can reduce the chance of the land becoming flooded during heavy storms. That allows us to learn what the ingredients are for sufficiently strong coastal defences. Such information is becoming increasingly relevant in light of the changing climate and expected increase in extreme weather.
Looking at muddy waters
‘Satellite images are also well suited for studying the quality of the water and the seabed. For example, we examine the interaction between sediment and the algae and animals that live in the water and seabed. This knowledge is important with respect to, for example, the dredging of estuaries for shipping.’
Radar seeks mussel reef
‘We also use radar images; these can observe, for example, the roughness of tidal mudflats. This way, radar can even be used to map mussel and oyster reefs on tidal mudflats. Now we can also make use of techniques like drones. These provide very detailed spatial information.
With all these forms of remote sensing, we are finding out how our coastal systems work and how they adapt to changing conditions and interventions. We are also learning how coastal processes help us, and how we can protect our coasts.’

Specialisation & Current positions
I am a physical geographer, specialized in coastal processes (PhD 1999, University of Amsterdam; postdoctoral research fellow from 1 Oct 1999 up to 1 Jan 2002 at Royal Holloway, University of London). In Mar 2002, I joined NIOO/NIOZ in Yerseke, focusing on remote sensing of tidal (eco)systems. Since Oct 2017, I am also part-time full professor at University of Twente, Faculty of Geo-Information Science and Earth Observation (ITC).
Publications can be found at my ORCID
Remote sensing of tidal (eco)systems
Theme
The central theme of my work is to assess interactions between organisms (such as saltmarshes, algae, shellfish) and their environment, shaping the estuarine, delta and coastal landscape, including both the bottom sediment and the water column. Topics also include the response of estuarine and delta systems to (climate) change and human impact, as well as risks (e.g., flooding) and services (e.g., nature-based flood risk reduction) of the coastal zone.
Current research topics
- Saltmarsh and mangrove development
- Solutions for nature-based flood defence
- Dynamics and management of (intertidal) sediments
- Structuring and functioning of benthic fauna communities
- Benthic-pelagic interactions in tidal systems
- Primary production of tidal flats and waters
- Suspended sediments and sediment transport in coastal waters
Methods & techniques
I use remote sensing techniques and geo-informatics to investigate coastal and estuarine systems and processes:
- statistical modelling, use of radiative transfer models, and big data analysis with remote sensing data (radar/SAR, optical and TIR satellite data, hyperspectral airborne/drone data and LIDAR airborne data, near-surface and field spectroscopy/measurements) for retrieval and forecasting
- spatial analyses in Geographical Information Systems (GIS)
- (time-series) analyses of remote sensing data using cloud platforms
- combination of earth observation with field surveys and experiments, and (hydrodynamic) models

Results from the EU FAST project
The EU FP7 project FAST (Foreshore Assessment using Space Technology), 2014-2018, has developed services to help design nature-based flood risk strategies in foreshores, based on earth observation data and big data analysis capabilities. The MI SAFE downstream service is currently not online anymore, but the data can be found here and the metadata can be found here.
