Dr. Sarker has more than 37 years of experience in River, Coastal and Delta Morphology and research. He has participated as a team member and as a project manager in a number of various research, study and consultancy work related with morphology at home and abroad. He has been serving CEGIS as a Deputy Executive Director (Development) since 2009. Before that, he was the Director and Head of River Delta and Coastal Morphology Division. His administrative responsibilities cover managing, monitoring and guiding the professionals of Research & Development, Remote Sensing, GIS, Database and IT divisions. His professional responsibilities cover working in fluvial morphology and relevant fields, especially in the field of river, delta and coastal morphology, predictions of river planform, monitoring the morphological development, environment impact analysis (EIA), tidal river management (TRM), subsidence, coastal morphology, planning and execution in the main rivers of Bangladesh; also in other civil and hydraulic engineering works.
In 2009, he obtained a PhD-degree at University of Nottingham, UK, based on a thesis on Morphological Response of the Brahmaputra-Padma-Lower Meghna River System to the Assam Earthquake of 1950. He did his M.Sc. in Hydraulic Engineering at IHE, the Netherlands, in 1996, and B.Sc in Civil Engineering, Bangladesh University of Engineering & Technology (BUET), in 1980. He has a list of publications in international journals and conference proceedings, along with book chapters. He is also author book title “Inland Navigation and Intregated Water Resources Management published by Acamadic Foundation, New Delhi, India”. He has participated in several special training courses on river morphology, EIA, project management, proposal preparation, GIS and Remote Sensing.
Dr. Sarker led a number of research to assess the dynamics of the Bengal deltas, evolution of the rivers in the subsiding Sylhet haor basin, morphological evaluation and developing prediction tools for predicting the morphological changes of the Ganges, Jamuna/Brahmaputra, and Padma rivers, along with the Koshi River in India. He has been actively engaged in many studies as Team Leader and his major responsibilities include morphological assessments and process of the river system and assess the responses of the rivers to human interventions, and climate change to assist in determining the design parameters for potential river training works and bank protection.
He is experienced to led many international projects such as to identify vulnerable reaches of the Kosi River, Bihar, India, morphological processes of the Brahmaputra River in Assam, India and worked as International Panel of Expert nominated by the World Bank, where major task includes assessing the impact of the Gorai flow on the salinity and morphology.
Dr. Sarker has long experience of working with ministries, departments, national and international development partners. He was a Member of the National River Conservation Commission (NRCC), People's Republic of Bangladesh.
