Since 2001 Dr. Schellekens has been working for Deltares where he is involved in projects and research related to hydrological modelling, watershed management and flood forecasting. Dr. Schellekens has extensive experience in (forest) hydrology, the hydrological implications of land-use and climate change, hydrological modelling (with special reference to flood forecasting) and hydrometeorological measurement techniques. In addition, Dr. Schellekens has lead a number of large projects related to (probabilistic) flood forecasting and has advised a number of leading meteorological agencies on the implementation of the Delft-FEWS flood forecasting system. Currently he coordinates the eartH2Observe FP7 EU project on global Earth Observation for Integrated Water Resource Assessment. His work has been published in leading scientific journals.
