Peter-Jules was one of the founders of Mobile Water Management and associate professor at Delft University of Technology teaching the master course Operational Water Management. In 2015 he died unexpectedly. He was our great inspirator and motivator. We miss him as a friend and colleague.
Since 15 years he worked on modeling and control of drainage and irrigation canals. His main interest was canal automation and more recently the application of smart-phones as device to improved water management practice. We continue his scientific work together with students and colleagues!
