Dr. Hannu Marttila has 12 years’ experience from studies of catchment management related issues. Main research topics are related to hydrology, land use and water quality issues. He have broad experience from various environmental engineering fields focusing on catchment hydrology and management, stream hydraulics, water protection issues and ecological connections.

The research has been published in more than 40 international peer-reviewed journal publications (ISI) and currently co-supervise 4 PhD students. He has done intensive co-operation with various research institutes and been visiting researcher in New Zealand, Canada and Spain. Marttila has been participating and managed several Academy of Finland, EU and foundation based projects. He is a chairman in Hydrology division at Finnish Water Association and hydrology subject editor for Boreal Environmental Research -journal.
