ET-CEM-MWM

Maarten Krol is an associate professor in integrated water modelling, with Ius Promovendi, and Programme Director of the BSc programme Civil Engineering and the MSc programmes Civil Engineering and Management and Construction Management and Engineering.

He holds a MSc and PhD in mathematical physics from Utrecht University, and has worked as a researcher at the National Institute of Public Health and the Environment (RIVM, Bilthoven, Netherlands), the Potsdam Institute for Climate Impact Research (PIK, Potsdam, Germany) and the Universidade Federal do Ceará (UFC, Fortaleza, Brazil). He joined the University of Twente in 2003 and since contributed to research and education of Civil Engineering and Management.

Water management is about matching natural physical processes and societal aspiration that go along with claims on water systems. From his background in integrated assessment modelling and mathematical physics, Krol is interested in using simulation approaches and scenario analysis to gain insights in this match. At RIVM, he was a core contributer to the IMAGE model on global and climate change; at PIK and UFC, he was principal investigator in a large bilateral German-Brazilian programme on drought in Northeastern Brazil in the context of climate change, giving to policy advice to the State Government of Ceará on drought management. At UT he was principal investigator in, among others, European projects on water savings in irrigation and on the water-land-energy-food nexus in EU policies, and currently on drought resilience in German-Dutch transboundary regions in the context of climate change.
