About Joost Delsman
Dr. Joost Delsman is an expert in the field of freshwater resources management. He focuses on groundwater – surface water interactions in coastal lowlands. Improving management of the adverse effects of salinisation of surface water is a key part of his work, as is the development of innovative solutions to improve local freshwater supply. Recent work includes assessing the long-term effects of sea level rise on groundwater salinity in the Netherlands using his developed national-scale groundwater salinity model.
He has worked on projects ranging from large scale groundwater and surface water modelling for regional to national policy consulting, to field scale process understanding through integration of measurements and modelling. In addition, dr. Delsman has also developed several innovative tools to facilitate stakeholder process understanding. He is currently involved in a number of international research projects, to develop operational freshwater management, to measure groundwater salinity using airborne geophysics, and to use late Pleistocene and Holocene landscape evolution to derive groundwater salinity in data-scarce areas.
Joost supervises MSc and PhD students, presents his work internationally and publishes in peer-reviewed journals.

Het Nederlandse grondwater wordt door zeespiegelstijging steeds zouter
De omvang en de gevolgen van zeespiegelstijging voor de zoetwatervoorziening, de waterkeringen en de ruimtelijke inrichting voor Nederland is onderzocht. Met de uitkomsten van dit onderzoek kan de Nederlandse samenleving zich beter voorbereiden. Het onderzoek door Deltares laat zien dat de verwachte verzilting van het Nederlandse grondwatersyst...
21 september 2022FRESHEM: Research into fresh water infiltration in Zeeland
FRESHEM Zeeland (FREsh Salt groundwater distribution by Helicopter ElectroMagnetic survey in the Province of Zeeland) looks at where fresh and salt water are located in Zeeland, and at what depth. This information can help farmers and market gardeners to meet their increasing need for fresh water.
