Mr Steijn is a civil engineer (Technical University Delft) specialized in river and coastal morphodynamics. Within ARCADIS, he holds the position of Director River, Coast & Sea and has nearly 30 years of experience in coastal research (river mouths and tidal inlets), river and coastal engineering (restoration, development and protection), and coastal policy (Integrated Coastal Zone Management, ICZM). As a coastal engineer he has designed coastal protection schemes in many countries across the globe, and as an ICZM expert he managed for instance the European Commission’s initiative on ICZM, called OURCOAST. In his capacity as river and coastal expert he has carried out many specialist assignments with the aim of early assessment into the causes of coastal and fluvial problems and the identification of possible solution strategies. For the Government of the Netherlands Rob holds a separate position as Dutch Water Representative. An important element in his work is the integration of various sciences and approaches, such as the development and application of eco-engineering design principles, based on the Building with Nature philosophy, the integration of coastal and marine techniques with spatial planning in light of climate change (coastal cities – Integrated Coastal Solutions), and increasingly the integration of technical sciences and approaches in often political driven, complex decision making processes (engineering – governance). Rob has been involved in the development of multi-functional tidal power generation schemes since the 1990s and is one of the discoverers of Dynamic tidal Power (DTP): the third way to harness ocean power.
