D.W.M.S.S.K. Dissanayaka – Hydrogeologist & Environmental Researcher D.W.M.S.S.K. Dissanayaka is a highly skilled Hydrogeologist and Environmental Geoscientist specializing in water resource management, hydrogeology, geophysics, and environmental geochemistry. With a strong foundation in geospatial analysis and geological engineering, their work focuses on sustainable groundwater management, disaster risk reduction, and the assessment of natural water resources. Currently serving as a Hydrogeologist at the Water Resources Board, Sri Lanka, Dissanayaka plays a pivotal role in long-term groundwater monitoring projects and international water regulation initiatives. Their expertise extends to GIS and remote sensing, facilitating data-driven decision-making in water resource planning and environmental conservation. Academically, Dissanayaka holds a Master’s degree in Water Resources and Management from the Postgraduate Institute of Science, University of Peradeniya, along with a BSc Special Degree in Geology from the same institution. Their research has significantly contributed to geochemical assessments of groundwater contamination, with notable investigations into metal distribution in groundwater and soil systems at critical dumpsites in Sri Lanka. Their professional experience encompasses both academia and applied geosciences. As a Research Assistant at the National Institute of Fundamental Studies and an Academic Demonstrator at the University of Peradeniya, Dissanayaka was actively involved in geological research, field studies, and student mentorship. Additionally, their involvement in the Japan International Cooperation Agency (JICA) landslide risk reduction project underscores their contributions to disaster resilience and environmental safety. Dissanayaka’s research portfolio includes publications on the economic potential of Sri Lanka’s granitic pegmatites, tectonic settings, and mineral resource assessments, with papers published in renowned geoscience journals. Their ability to integrate geophysical techniques with hydrogeological modeling has been instrumental in advancing sustainable water management solutions. With a strong foundation in environmental policy, geotechnical analysis, and groundwater sustainability, Dissanayaka continues to drive impactful research and innovation in hydrogeology and water resource engineering. Their expertise in spatial data analysis, environmental risk assessment, and geological surveying positions them as a key contributor to Sri Lanka’s geoscience and environmental research sectors.
