Expertise

  • Remote sensing, Earth Observation and Geo-Information Science
  • Coastal, estuarine & delta systems
  • Geomorphology, biogeomorphology, biophysical interactions & benthic ecology
  • Nature based flood defence & ecosystem based solutions
  • Aquatic systems and water quality

Specialisation & Current positions

I am a physical geographer, specialized in coastal processes (PhD 1999, University of Amsterdam; postdoctoral research fellow 1999 up to 2002 at Royal Holloway, University of London). 

In 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 the University of Twente, Faculty of Geo-Information Science and Earth Observation (ITC).

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. 

Current research topics

  • Saltmarsh development
  • Solutions for nature-based flood defence
  • Dynamics and management of (intertidal) sediment
  • Structuring and functioning of benthic fauna communities
  • Primary production of tidal flats and waters
  • Benthic-pelagic interactions in tidal systems

Methods & techniques

  • forward and inverse modelling with remote sensing data (radar/SAR, optical and TIR satellite data, hyperspectral and LIDAR airborne data, near-surface and field measurements), 
  • spatial analyses in Geographical Information Systems (GIS)
  • combination of earth observation with field surveys and experiments, and (hydrodynamic) models

Feature EU FAST:

Foreshore Assessment using Space Technology

 

FAST is developing services to help design nature-based flood risk strategies in foreshores, based on earth observation data and big data analysis capabilities.
