We are sad to report that Ben Engelen, a prominent representative of IAH’s Regional Groundwater Flow Commission (RGFC), passed away on 10 June 2018. He is the author of two very well-known books: Developments in the analysis of groundwater flow system and Hydrological systems analysis: Methods and Applications. In 2013 Ben presented a lecture about energy systems, and groundwater flow systems being a part of energy systems, during RGFC’s Xi’an international symposium. Apart from hydrogeology, Ben was interested in a large range of fields: the systematic approach, number theory, atomic physics and soil erosion.
