Understanding Hydrological Processes in an Ungauged Catchment in sub-Saharan Africa

Marloes Mul received her MSc in Civil Engineeringfrom Delft University in 2007. Between 2004 and 2007 she worked in Africa (Zimbabwe, Tanzania) on her PhD for UNESCO-IHE. As of January 2008 Marloes returned to UNESCO-IHE in The Netherlands as lecturer Water Resources Management, where she is now coordinating the MSc programme Water Management.
