An Introduction to Advanced Fluid Dynamics and Fluvial Processes

Professor B. S. Mazumder is a former Visiting Professor at the Department of Civil Engineering, Indian Institute of Technology (IIT), Bombay. After his retirement from Indian Statistical Institute (ISI), Kolkata, as a Professor and Head of the Physics and Applied Mathematics Unit, and In-Charge of Fluvial Mechanics Laboratory, Professor Mazumder joined as an Emeritus Fellow at the Department of Aerospace Engineering and Applied Mechanics, IIEST, Shibpur, and as a Visiting Professor at the Civil Engineering Department of at IIT Bombay. Soon after his Ph.D. Degree (1976) from the Indian Institute of Technology (IIT), Kharagpur in Applied Mathematics (Fluid Mechanics), B. S. Mazumder joined as a Post-doctoral Fellow at the Indian Statistical Institute (ISI), Kolkata, to work on the problems of Applied Fluid Mechanics with Professor Supriya Sengupta, Geologist and Professor J. K. Ghosh, Statistician. Since then, he has been working on various problems of inter-disciplinary nature, in the areas of Turbulence, Fluvial sediment transport, Particle-size distributions, Combined wave-current flows over bedforms, Convection-diffusion process, Flow visualization and image processing, Navigation hydraulics, Flow and heat transfer. He took initiatives and was instrumental to upgrade the existing laboratory, and named as Fluvial Mechanics Laboratory (FML) at ISI Kolkata with sophisticated equipment and excellent research facilities. A hi-tech laboratory is developed to elucidate various problems of statistical fluid mechanics related to turbulence and sediment transport. He received the financial supports from ISI, INSA, DST, DOD, NBHM and CSIR for several interdisciplinary projects. During the period 1989–1991, he worked as a Guest Scientist at the Illinois State Water Survey, UIUC, USA to work on turbulence generated due to navigation traffic in Mississippi and Illinois Rivers. During his tenure at ISI, Kolkata, he supervised nine Ph. D. Theses, seven Postdoctoral Fellows and ten Project Assistants.

As an Emeritus at IIEST Shibpur Prof. Mazumder was closely associated with the Hydraulics and Fluid Mechanics Laboratory. He was also involved as a Visiting Professor (2015–2021) in the Civil Engineering Department of IIT Bombay. During this period, he shared his innovative ideas in the development of the Hydraulics Laboratory in the department. He mentored 12 Ph. D. Scholars of different premier universities and institutes. He has more than 170 research papers to his credit in peer-reviewed journals, like JFM, Proc. Roy. Soc., Physics of Fluids-AIP, JGR, WRR, AWR, FDR, JHR (IAHR), JHE (ASCE), JFE (ASME), IJHMT, Sedimentology, Sedimentary Geology, SERRA, ESPL, etc. and many national and international Conference Proceedings. He visited several places in India and abroad, and delivered invited talks. He is a Fellow of Indian Society for Hydraulics (FISH). Prof. Mazumder was a Guest Scientist/Professor at different Universities, like the University of Illinois at Urbana-Champaign (UIUC), California Institute of Technology (Caltech), Stanford University, University of California-Davis (UC-Davis), UC-Santa Barbara (UCSB), Rensselaer Polytechnic Institute (RPI), New York, MITCambridge, University of Minnesota, Minneapolis, SUNY-Binghamton, USA, University of Western Ontario, Simon Fraser University (SFU)-Canada, Nottingham University, Sheffield University, UCL, King’s College, Cambridge University, UK, University of Stuttgart, University of Munich, University of Karlsruhe, Germany, ICTP-Italy, Technical University of Denmark, Tsinghua University, Beijing and many others. Prof. Mazumder is still deeply engrossed in his research domain.

Dr T. I. Eldho is a Professor & Former Head and Chair of the Department of Civil Engineering, IIT Bombay. He has more than 30 years of experience in the area of water resources and environmental engineering as a Scientist, Professor and Consultant. He works in the areas of Fluid Mechanics, Turbulence, Hydraulics Coastal Hydrodynamics, and Climate Change Impact on Water Resources, CFD, Groundwater Flow, and Contaminant transport. He got his Ph.D. from IIT Bombay in 1995 and worked as Postdoctoral Fellow at the Institute for Hydromechanics, University of Karlsruhe (currently Karlsruhe Institute of Technology), Germany during 1996–1998. During 1998–1999, he worked as Water Resources Modeler and Consultant at Mott MacDonald Company in Cambridge UK. Later Dr. Eldho worked as a Senior Research Fellow at Hydrotech Research Institute, National Taiwan University, Taipei during 1999–2000. In 2000, Dr. Eldho returned to India and joined at Department of Civil Engineering, IIT Kharagpur as a Faculty. Further Dr. Eldho joined IIT Bombay as a Faculty in 2001 and continued his teaching, research, and professional career. He has developed Hydraulics Laboratory of IIT Bombay with many sophisticated equipment and facilities.
