Welcome to Guna Hewa's homepage! Guna is a Civil Engineer and a Hydrologist. Dr Guna Hewa was raised and educated in Sri Lanka, completing her Civil Engineering degree there in 1994. Guna's introduction to the field of hydrology commenced when she completed her Masters in Hydrology in 1996, for which she won a prestigious Irish government Fellowship. The next step in Guna's career was moving to Melbourne to undertake a PhD at the University of Melbourne, which Guna completed in 2001.

Guna joined UniSA in 2003, and since then, she has been educating both undergraduate and postgraduate students in Hydrology & Water Resources Engineering. She has also been the Program Director for Masters of Water Resources Management, delivered through... Read more
