Dr. Lal Muthuwatta is a hydrologist by training with a specialization in numerical modeling for water resources management. His research and professional background include over 20 years of experience in the fields of GIS, remote sensing, and numerical modeling. He has worked in multiple river basins across Asia and Africa, including Ganges, Salween, multiple river basins in Sri Lanka, and Karkheh in Asia; and Volta, Tana, Nile, and Naiwasha in Africa. He has worked on issues related to hydrological assessments, climate change impacts, and water resource management with a focus on the agriculture sector. He has contributed to more than 40 research articles published in various scientific journals. In 2010, 2014, 2015 and 2018 he was awarded the prestigious Sri Lanka presidential award for his research work. He has been a visiting lecturer at various universities in Sri Lanka. Lal holds a PhD in water resources management and hydrological modeling from the University of Twente, The Netherlands. As part of the PhD research, he has developed a numerical model to assess the spatial and temporal water availability in the Karkheh river basin in Iran. His research interests are to work with remote sensing and numerical modeling to study climate change impacts on water resources in river basins/regions.
