Gualbert Oude Essink

Dr. Gualbert Oude Essink is an Associate Professor at the Faculty of Geosciences, Department of Physical Geography at Utrecht University. He is also a senior hydrogeologist at Deltares, specializing in coastal groundwater systems, saltwater intrusion, and delta sustainability. His work focuses on improving freshwater availability in vulnerable coastal zones under climate change, subsidence, and anthropogenic pressures.

Dr. Essink holds a PhD in Civil Engineering from Delft University of Technology and has extensive experience in applied hydrogeology. He leads research projects globally, including in the Netherlands, Egypt (Nile Delta), Bangladesh (Kulna region), Singapore, and Vietnam (Mekong Delta). Key initiatives include GO-FRESH (Aquifer Storage and Recovery) and Rise and Fall (Mekong Delta subsidence strategies).

His research integrates modeling, geophysical surveys, and stakeholder engagement. Notable areas include variable-density groundwater flow, airborne electromagnetic surveys for salinity mapping, and sustainable groundwater management. He supervises multiple PhD candidates and teaches at IHE Delft, contributing to global water education.

Dr. Essink has authored over 100 peer-reviewed articles, focusing on delta sustainability, climate impacts, and groundwater systems. His work bridges academia and practice, addressing freshwater security challenges in coastal regions through innovative solutions like managed aquifer recharge and saltwater intrusion mitigation.
