Hans Middelkoop, Utrecht University
Hans is full professor in Global Change Geomorphology at the Department of Physical Geography, Faculty of Geosciences of Utrecht University. He is scientific director of the UU research programme ‘Water, Climate & Future Deltas’, that contributes to the development of management strategies and pathways to sustainable deltas worldwide under global change. His main research interests are the evolution and dynamics of rivers and deltas under changing climate and human interaction. His work on deltas focuses on understanding the natural and human subsystems, and how these determine present-day and future functioning of deltas worldwide. Key issues are flooding, land subsidence and access to fresh water in sinking deltas.
