Prof. Dr. Leo van Rijn
Prof. dr. Leo van Rijn is an independent consultant since his retirement in 2011 from Delft Hydraulics/Deltares and the University of Utrecht and has over 40 years experience in basic hydraulics (river, tidal and coastal flows), sediment transport and morphology of rivers, estuaries and coasts. He has participated as a team member and as project manager in many hydraulic and morphological studies in the Netherlands and abroad, using both physical and mathematical models. Various mathematical models have been developed to compute the sedimentation of channels and basins. Another activity has been the development of instruments for measuring in-situ velocity and sediment transport in rivers, estuaries and coastal seas.
He has written five books about fluid mechanics, morphology and sediment transport:
- Principles of fluid flow and surface waves in rivers, estuaries, seas and oceans (1990,2011);
- Principles of sediment transport in rivers, estuaries and coastal seas (1993, 2012);
- Principles of coastal morphology (1998);
- Principles of sedimentation and erosion engineering in rivers, estuaries, coastal seas (2005, 2012);
- Manual of sediment transport measurements (1986, 2007).
Michel van Staveren
After graduating from technical college (electronics, electrical engineering and computer science), Michel van Staveren worked in the process industry, the semiconductor industry and as a RD&E software developer. He founded Jato Cleanroom Supplies in 2007. Due to his activities as a RD&E software developer, he has extensive experience in all aspects of innovative control systems, measurement sensors and their applications. Since 2015, he collaborates with WaterProof on the development of the prototype buoy JaT01. This prototype is a scalable platform with a wide choice in components. Depending on the application, different forms of sensors, energy supply (batteries, with or without solar panels) and various communication options (Lora, GPRS or satellite) can be chosen.

Dr. Ir. Hessel Voortman
Dr. ir. Hessel Voortman (Hessel Voortman Engineering Consultancy) is an independent expert specializing in hydraulic engineering structures, such as locks, weirs and storm surge barriers, as well as water safety. Hessel has more than 25 years of international experience as consultant, designer and project manager in planning studies, tendering (both on the public and private side) and execution of large projects. He has worked on the Merwedebrug A27 (tender), “Brouwersdam” culvert (planning study), structures in the “Afsluitdijk” structures (tender and implementation design), the sea locks in IJmuiden and Terneuzen (tender and implementation design), widening of Twente canals (planning study) and expansion of Afsluitdijk sluice gates (planning study). Aside from numerous Dutch projects, Hessel has worked in among others Belgium, Sweden, the United States and South Korea.
Hessel’s approach is “theory in practice”. He operates on the basis of content at the interface of design, implementation and science. He translates the information requirements of the design into work programmes for hydraulic modelling. Often, existing models turn out to be inappropriate. In those situations, Hessel initiates the development of customised models or he builds them himself. He regularly acts as intermediary for knowledge institutes to ensure that knowledge and practice are well connected in view of project goals. Hessel is author or co-author of more than thirty scientific publications and conference contributions.
