Tjeerd Bouma (NIOO-CEME)

Tjeerd Bouma (for detailed information see )

Dr. Tjeerd J. Bouma studies at the NIOO-CEME department of Spatial Ecology the capacities of organisms (e.g., plant species) to modify their environment by changing physical conditions of currents, waves and sediment transport (i.e., ecological engineering), and vice versa, the effect of physical conditions on plant growth. In 2002, he coordinated a large field campaign on hydrodynamic conditions on mudflats and salt marshes (Bouma et al. 2005a). Related experiments were done both in a flow flume and a wave flume, to link plant traits to the ecosystem engineering ability (Bouma et al. 2005b). In 2003 he coordinated a field campaign on seagrasses in East Kalimantan (Evrard et al. 2005). He is currently involved in a MC-fellowship granted to Dr. F. Brun and supervises 2 national grants on the interaction of vegetations and hydrodynamics, and is one of the principle investigators in the responsive mode 17 on “The role of native and/or invasive ecosystem engineers in explaining biodiversity“ within the EU network of excellence MARBEF.

Geologist, Leiden univ., PhD on taphonomy of molluscs 1968. Since 1967 at (Royal) Neth. Inst. for Sea Research to work on phytoplankton (resulted i.a. in long term Marsdiep time series). Became interested in bioturbation during his work on microphytobenthos, which can grow only in the top millimeters of the tidal flat but occurs down to 35 cm! This resulted in quantitative field-measurements on sediment reworking by worms Arenicola (1976) and Heteromastus (1979) and birds (1990) and review papers in 1998 and 2001. Since 2003 retired guest researcher at Royal NIOZ.

Alessandra Crosato (IHE)

Dr. Crosato graduated in Hydraulic Engineering from the University of Padua in 1986. Since then she gained a wide experience from projects dealing with the morphological changes of alluvial systems. Her expertise covers the entire river system, from the source to the sea, including the coast adjacent to the river mouth and the submarine canyon. In the Netherlands, Dr. Crosato worked in projects regarding the Westerscheldt, the Oosterscheldt, the Grevelingen, the Waddenzee, the Nieuwe Waterweg, the Rhine and Meuse Rivers. In Italy, she dealt with the optimization of reservoir operations taking into account environmental flows and stress, as well as flood hazards from rivers and contributed to several studies related to the works in defense of the city of Venice.
As a researcher, Dr. Crosato developed numerical models simulating the river morphological evolution and aquatic habitats. Her research experience includes laboratory experiments on sediment transport and morphology of alluvial systems under current and waves. River meander migration research has led to the development of a state-of-the art computer model for the prediction of river planimetric changes. Current research topics mainly deal with the development of bars inside river channels, bank erosion and accretion and the effects of floodplain vegetation as well as of large floating debris on the short- and long-term river morphological developments, with emphasis on the effectiveness and impact of river engineering and rehabilitation projects. Dr. Crosato obtained the doctoral degree from the Delft University of Technology (TUDelft) in 2008. She is now a member of the UNESCO-IHE staff, where she teaches graduate courses on River Morphodynamics, River Training and Rehabilitation, the River System, Environmental Flows. She also contributes to the course Biogeomorphology of TUDelft. She currently supervises several MSc and PhD students.

Maarten Kleinhans (UU)

Maarten Kleinhans, Ph.D. Utrecht University, studies the relation between benthos and sediment dynamics in measurements on the Dutch shoreface. In specific, the transport processes of sand and mud are measured, the bedforms and concurrent sedimentary stratification are mapped from boxcore profiles, and the mud content of the bed surface and lower layers are measured. The active layer thickness is determined by bedform activity and benthos activity.
In turn, the mud entrainment and inmixing is determined by the active layer thickness during storm and calm conditions, respectively.

Cristian Picioreanu (TUD)

Associate professor at TU Delft, Dept. of Biotechnology, Environmental Biotechnology group (since 2004), Ph.D. TU Delft (1999, “Multidimensional modeling of biofilm structure”), M.Sc. University Politehnica of Bucharest, Romania (1990, Chemical Engineering). Broadly, his research explores by computational methods (numerical modelling) complex interactions between physical, chemical and biological processes in microbiological systems. In particular, the work on modelling the development of microbial biofilms has received wide international recognition. Multidisciplinary biofilm models integrate microbial growth/ decay/ detachment/ motility, solute transport/ reactions, hydrodynamics, mechanics or electrochemistry. Models have been applied mainly in environmental (bio)engineering (wastewater treatment, aerobic/anaerobic granular sludge, microbial fuel cells, biocorrosion, biofouling, soil biocementation/ biogrouting), but also in microbial ecology (phototrophic mats) and medicine (dental biofilms, antimicrobial action). Current activities on biofilm modelling include an NWO/VIDI project and teaching in several international courses. More detailed information at:

Stijn Temmerman (U-Antwerp)

Stijn Temmerman is working at the University of Antwerpen (Belgium) as a teacher-researcher. His research focusses on the interactions between plant growth, water flow and sedimentation/erosion, and how these interactions lead to spatial self-organisation of both geomorphic and vegetation patterns. This is studied in tidal marsh landscapes. New research is planned in sub-polar regions.

Stefan Talke (UU)

Stefan Talke recently received his PhD from the University of California, Berkeley for research that concentrated on the hydrodynamics and sediment dynamics of an intertidal mudflat. Currently he is working with Huib de Swart on a LOICZ funded project in the IMAU institute at the University of Utrecht. The goal of the project is to investigate biological and hydrodynamic processes and feedbacks at the Estuary turbidity maximum of the Ems river, from both an experimental and numerical modeling standpoint. Both short term change on the scale of the tidal cycle and longer term change (years) due to increased dredging are being investigated.

Daphne van der Wal (NIOO-CEME)

Dr. Daphne van der Wal (1969) studied Physical Geography at the University of Amsterdam, and specialised in geomorphological processes of coastal systems, and in Geographical Information Systems (GIS). Between 1992 and 1996, she carried out several scientific projects for Rijkswaterstaat, including a study on the effects of sand-drift on the vigour of marram grass in coastal dunes, and a study on the ecological effects of beach nourishment, in co-operation with NIOO-CTE. Her PhD research was on aeolian transport of nourishment sand in beach-dune environments and was sponsored by the Cornelis Lely Stichting. She obtained her PhD degree from the University of Amsterdam in 1999.


Between 1999 and 2002, she worked as a post-doctoral research fellow at Royal Holloway, University of London, studying British estuaries and salt marshes. Her research focused on the development of tools to assess and predict likely effects of changes in environmental forcing factors (such as sea level rise) and human activities (such as channel dredging) on estuarine morphology and saltmarsh development. The research was part of a grant from the Leverhulme Trust, and part of the UK Estuaries Research Programme.


In March 2002, she joined the NIOO-Centre for Estuarine and Marine Ecology, to introduce GIS and remote sensing to the Spatial Ecology department. Research themes include the use of remote sensing (i.e., satellite radar, optical, near infrared and thermal infrared remote sensing, as supported through projects with ESA and NASA, and airborne hyperspectral remote sensing) for the physical characterisation of intertidal flats as a basis for macrobenthos mapping and prediction, and the use of remote sensing and GIS to assess the development of pioneer salt marsh and its causes.

Short c.v.

Jérôme Fournier (France)

I am a Research Scientist at the CNRS (National Centre for Scientific Research) since 2001 and I am working in a Marine Research Unit of the MNHN (National Museum for Natural History) based in Dinard (Brittany, France). I completed my Ph.D. at the University of Rennes (2000) and a Post-doc position at the EPHE (Practical School of High Studies) of Paris (2001).


I am involved in several international, european and national projects related with the biosedimentology and the biogeomorphology of tube-dwelling worms and worm reefs in several areas of the world. The main models are Lanice conchilega,Sabellaria alveolata and Phragmatopoma caudata. The aim of the research is to understand the interactions between polychaetes and sediment and the morpho-sedimentary characteristics of reef-building tubeworms.



Zehao Shen (China)

Doctor and associate professor in the Department of Ecology, Peking University in China. Most of my work was about the relationship between vegetation and its environment, especially at the scale of community to region. I am fond of the effects of topography and geomorphological processes on the spatial pattern of vegetation and species distribution, and the maintenance of biodiversity. I am now studying the topography effects on the spatial of ecological processes, such as forest disturbance, seed dispersal, and the impacts of soil erosion on the land use and ecosystem management in a watershed. I am anticipating and contributing to the coming of a new era for the long-existing but underestimated paradigm in understanding of the relationship between biotic and the abiotic world.

Jinyong Zhao (China)

After I graduated from university in the major of riverbank collapse treatment, I worked mainly about riverbank protection, ecological riverbank protection and river restoration in China Institute of Water Resources and Hydropower Research. Now, I am involved in several projects related with river restoration in China. The methodology of these projects include data collection, digital simulation and pilot projects, etc.


Tony Stallins (USA)

I am currently an Assistant Professor at Florida State University in the Department of Geography.  I completed my Ph.D. at the University of Georgia in August 2000.  

I am investigating how biogeomorphic interactions mold patterns of plant species composition and diversity in coastal and riparian systems. The overarching goal of this research is to articulate and test hypotheses about how complex systems interactions shape biogeographic patterns.
